EVscope: BUSTED

a hundred times more powerful than a classical telescope well that's good scam written all over it so it is also easy to control with your smartphone thus making astronomy easier to share okay now I'm sure if you've ever looked through a telescope before there are a couple of things you never do never you'll never touch the telescope while you're looking through it especially something as flimsily mounted as this it just shoots the image way too much secondly are you seriously trying to astronomy from inside a brightly lit conservatory two million dollars raised as well look it's even got pictures of a normal telescope in the evey scope well I can't be right I ever a normal telescope and this is what a picture of the Eagle Nebula looks like through my telescope on m16a2 moves the exposure to a star is some insignificant fraction in the universe right our exposures finished of the Eagle Nebula there he is is the thing that's the eagle obviously this is the thing that Hubble took all pictures of they call the pillars of creation and the areas of star formation whether you but if you were like the Hubble telescope or something I could believe it but this ain't a hundred times better than any of my telescopes and none of my telescopes are particularly fancy look you're talking about what you can see through the eyepiece right yes later I thought of an instrument capable of accumulating light in a unique way accumulating light in a unique way what you mean like astrophotography is been doing for the last 100 plus years you just point the telescope at one point in space and accumulate more and more light and then you can display it on a computer screen or be aware somewhat I mean that's not what you're doing you've done something completely unique right capable of accumulating light in a unit quí so we could finally see those neighborly those galaxies all in a matter of seconds and directly through its lens loop they've just put an imager at the prime focus of the telescope damn this was nothing new when I was doing it about 10 years ago and even back then if I put a digital SLR at the prime focus of the telescope I could take pictures like this in about 10 seconds or like this in about two minutes so basically the evey scope doesn't have an eyepiece you can never look through the telescope and that fundamentally limits what it can do I think what you actually mean is you're gonna stick a gimmick viewer on your telescope which led to be honest if you're going to have a viewer don't put it on the telescope like it was saying if you're taking long exposures or trying to record anything through a telescope the last thing you want to do is touch the telescope because it shakes the telescope and that's true if your telescope is mounted like a tank like this one but doubly so if the mounting on your telescope is flyweight and she I thought it was amazing I actually majored in physics and was really interested in astronomy when I was at MIT and really used to look through a lot of hobby telescopes and this was some of the best that I've seen now the only guy who would make a comment like this he only knows almost nothing about astronomy back didn't he see that it was he did his degree in astronomy or something well buddy's listed here as as John Hopkins University I wonder what department he's in psychology and brain science maybe just maybe that was something more pertinent and worth mentioning than just name-dropping MIT look almost no one especially someone who does astronomy as a hobby would use a scope this small because it simply lacks optical performance unless for the moment just take the best claim that the evey scope makes at face value that it can record images like this comparable toilet you could snap you know ten seconds ten years ago but that's basically the only thing the Eevee scope can do and let me tell you something back in the day when you had a freeze your ass off manually guiding the scope for about half an hour to get an image on chemical film to get a picture like this it meant something it took skill and dedication so now I can just push a button and 44 seconds later this pops up on the camera sure it looks awesome but the easy button also means the Nulty of seeing this sort of thing wears off pretty quick when I saw was this vivid intensely colored planetary nebula just like the photographs you see in books sure that's the dumbbell nebula one of the brightest and most easy to photographed nebulas in the sky I mean it's like a 30 second exposure I took of it some 10 years ago and he is what it looks like if you do a search for it online so what you're looking at is it's beautiful isn't it it's the dumbbell nebula star that exploded there's a tiny little camera at the top which is picking up the image from the light from the object we're looking at and it's sending that to a projection device which you're looking through just taking individual pictures over every few seconds and slowly it's overlaying those so you're starting to see a better and better image you'll never get to see that through a normal telescope no no you could never do that with a normal telescope and unless you've got a camera say for instance in which case you see something like this about 30 seconds later congratulations you've just reinvented Astro photography you'll never get to see that through a normal telescope the simple reality is visual astronomy feels a lot more personal when the photons from that distant galaxy or whatever are actually falling into your eyes rather than just you know looking at an iPad or looking at an iPad through and lens for some bizarre reason so about ten years ago I took this photograph of the m101 supernova very impressive there it is a star burning almost as bright as the rest of the galaxy but the simple reality was that even though it looked nowhere near as impressive looking at it visually through the telescope in fact that you were looking directly at a star that was exploding as bright as the rest of the galaxy put together was actually a much more profound experience 20 million years ago long before mankind was even walking upright let alone back in the rocks together a white dwarf star and a distant galaxy reached a critical mass and exploded with a violence that can scarcely be countenanced that such a brief time it's song with comparable luminosity to the rest of the entire galaxy supernova now some 20 million years later that lights just about to reach the earth until it's shining on me right now the telescope's pointed right at it it's just you can't see it yet because it's lost in the late evening Twilight however later in the full dark I'm gonna show you the supernova it's sort of the difference between looking at photos and actually being there there's a whole different ambience to it and honestly for me some of my most enjoyable astronomy moments are things like when I was just dozing under the desert stars with a cheap pair of binoculars which are awesome for the price and you know you periodically wake up and you look around at the sky watching the Eternity of the heavens scrolling to view as the Earth rotates so for imaging deep sky objects the V scope offers performance of a bare thousand dollar type imaging platform for the amazing price of three thousand dollars with the obvious exception that with a regular telescope you can do other things with it because it doesn't have a sensor locked in there at the prime focus of the telescope so how badly would this limit the performance of the e V scope telescopes typically look at a small area of the sky and just a demonstration right this by curious chance back in 2011 I actually did this video of a zoom in on the patch of the sky when the Eagle Nebula is just give you a feel for the size of the object that you're typically looking at and the Eagle Nebula is relatively big compared to the small objects in the sky which are things like planets I mean in May noticed on my channel you know when I do something Astro it's very rarely of here is a picture of a nebula you know it's frequently about watching the solar system move watching solar flares or the rotation of the Sun watching the rotation of the moon or sunset on the craters on the moon the rotation of Jupiter something that you can record over the period of a night or the movement of a Uranus and its moons against the background stars or the transit of Venus or solar eclipses or whatever there are a lot of interesting things in the solar system things that are different every time you look at them none of which you could really look at through the evey scope most notably the planets I mean it'll be outclassed easily by a telescope that costs one tenth of the price Michael planets are some of the most interesting things to look at in the sky the moons of Jupiter the rings of Saturn the phases of the Moon of Venus Venus Dallas game yeah that's just give you an idea of how much touching the telescope will shake things up and just so we're all clear on the rough dimensions this is Venus seen for about a but a four hundred dollar telescope ur a five inch max Uthoff Cassegrain and the size of the planet there is about the same angular size as jupiter appears and this is Jupiter seen through a significantly more expensive telescope ur about an 8-inch schmidt-cassegrain yes the chips are a little further on just put the camera up on the earpiece but again to see detail on Jupiter you're critically dependent on how still the atmosphere is which is why Saturn looks so depressingly bad here because of the atmospheric shimmer none of these things will be good through this 3000 dollar telescope with the possible exception on the moon and just to give you a feel of the performance that you might expect this is the sort of thing you would expect to get off the Evie scope which is locked off a prime focus whereas this is the sort of image you'll get out of a telescope that costs one-third the amount of the Evie scope and that's what you'll see life from the eyepiece you see telescopes are limited by two things resolution and the light-gathering resolution defines how small or how close together two things you can actually split up with the telescope and light-gathering defines how faint an object you can see so double the diameter of the telescope and you can see things about half the size so if you're trying to resolve double stars double the diameter of the mirror or the lens you can about half the angular size at which you can split up two stars or something or if you're looking at a planet you increase the number of visible features on that planet by a factor of four doubling the diameter of the mirror means you double the area of the mirror which means you've got drupal the light that you gather with your telescope so a normal classical 18th telescope like this would gather four times as much light as the evie scope and it'll give you a four times as much detail on jupiter as the evie scope so at this point how do you not call the Eevee's scope branding itself as a hundred times more powerful than a classical telescope a simple fraud hole looked up another way the evie scope has the optical performance of a hundred and fifty dollar telescope for an amazing three thousand dollar price tag so with a normal telescope me prime focus will give you a view of a rather large area of the sky which is not so bad for a big faint object but if you want to look at small object you need an eyepiece in there just so we're all on the same page here this is what the Eevee scope claims its field of view will look like Jupiter is one of the angular Li largest planets that you can see and this is how big it would appear through the Eevee scope you actually be better off for looking at Jupiter buying the hundred and fifty dollar telescope because you can put an eyepiece in there which increases the magnification the resolution of the telescope is exactly the same as defined by the MERIS eyes but the eyepiece allows that image to appear bigger yes the chips are a little further on just for the earpiece and there is no way of doing this on the Eevee scope you are locked in at a certain magnification it's okay for some deep sky objects but it's going to suck for planets but even if you could put a eyepiece into this four and a half inch entry level scope it just wouldn't compete the sweet spot for telescopes is about eight inches it's just the magical spot between ease-of-use cost and performance it's about four times the light-gathering of the evey scope and four times the detail that you would see on a planet like Jupiter or Saturn and at this point you're gonna realize that astronomy is not and never will be a push-button hobby telescopes have to focus light within a wavelength of that light which is less than a micron you have start to need know things about how to keep your optics clean how to collimate your telescopes and maintain a good focus she'll learn that you can leave the telescope outside to equilibrate the temperature to get the best optical performance and so forth you learn how the planets move and how the earth spinning on its axis and trav the Sun alters what you see at nighttime at different times of the year me he started astronomy with a three-inch refractor it was exceptionally limited almost as bad as the Evie scope I was a 10 year old kid with a hundred dollar telescope I got for Christmas struggling to do anything I knew nothing and in the end yes just trying to find a star with the telescope that turned out that bright star that I wanted to look at turn out to be satyr and I was completely blindsided by this that all of a sudden all there I was just looking for a star in the sky and you see Saturn as this perfect little gem just sat there on the Velvet Matte of space it was one of the most awesome and formative experiences of my life and from that moment on I was committed many years after livering babies later I got myself an eight inch Dobsonian which is the basically the best optical performance for the least dollars but it gets the job done and I still use it when I go back to England so it's maybe the first thing that you learn when you look through a telescope is damn is the earth spinning quickly the Earth rotates well more is once per day and if your telescope isn't driven and things are going to drift out the feel of you pretty quick so you need to drive the telescope mount to compensate for the Earth's rotation well if you telescopes got no Drive like my early telescope dead you've got to compensate for the Earth's rotation yourself it takes some getting used to it takes some skill turn off the tracking the it's gonna continue rotating so this is what happens if you're if your scope is increment so I'm turning off the tracking three two one now so that what if you're looking at there is the rotation of the earth so you see things drift out of the field at quite a rate but ENC a day it's actually it's a fair fair job just why I should keep the telescope pointing in the right direction now you used to it fairly quickly you know County which way it's rotating you've got to get over here somewhere and you let it drift through the field of you yeah nice view of it and you'll bring it back again and so it keeps going and finding the faint objects take some skill and learning about star hopping and averted vision if you look directly at the first patch because your eyes aren't when you look directly out something and use the color sense to portion of your eyes which isn't actually that light-sensitive however when you look away from these things using something called averted vision then you use the as it the cones that's the cones cones at the sensitive point and when you do that from this fuzz patch you start to resolve it this millions and millions of stars and you it's in this sense that global clusters redo of this wow factor to them now if you got a bit more money than I did and you're really not into sort of moving the telescope yourself you can get a mount that compensates for the Earth's rotation but again to set it up you've got to understand some stuff so there are two types of mounts that do this the first is simple one of the telescope's axes is parallel with the Earth's axis of rotation and then he just rotates and well it's per day around that axis and that's it that's all you need to do and in practice they look like this the german equatorial mount so just set it up all you got to do is align what i was accessed parallel to the axis the Earth spins on you're basically done now it turns out to do that about right ain't so difficult to do it precisely Church that the telescope points at exactly the same point within the resolution of the telescope over the period of hours that's still pretty hard work but if you want something it's roughly aligned it's this simplest thing to set up ever you just go outside you point that axis due north with an elevation equal to your latitude and boom you're done now such amount will more or less double the price of your telescope but after that tracking is not so bad then you get the ultra smooth type tribes which are in some ways easier to set up in some ways more of a pain in the ass the first thing you've got to do is tell the telescope where you are on earth it needs to know the latitude and the time more advanced ones will do this by GPS then the telescope needs to know what it's pointing at so you have to point at the bright star and things to the telescope notice the time from that it works out how it's gonna drive itself to track whatever it's pointing at now none of this is remotely new my sky cannon here would do this over a decade ago after three years of development we now have a fully working prototype that we demoed also known but we need to support to go further join us and transform astronomy forever and it wasn't particularly new technology back then now when you know what you're doing here setup only takes a few minutes and further once the telescope knows what it's pointing at and all that sort of thing it'll find objects for you which in some ways is nice in some ways not so much a lot of the fun that you get out of visual astronomy is actually finding the object yourself now there are next generation type caches that will actually do all the alignment for you so you need to know absolutely nothing you just plug it in and it sort of moves around for a bit and it finds some bright stars on its own and again those have been available for a couple of years now mmm fairly pricey but they're available so if you wanted a four and a half inch go to type telescope it would set you back about three hundred dollars and that gives you exactly the same optical and tracking performance as the three thousand dollar Evie scope sorry it'll give you inferior optical performance because we're the three hundred dollar telescope it still has the versatility that you can either use it as an optical telescope by sticking a an eyepiece in it or using it for imaging by sticking a camera on it now you can sort of see the market that they were aiming for here you know the push button iPhone generation just push a button on the telescope and boom it will do everything for a year for three thousand euros now for the record three thousand dollars all you a top banana Rolls Royce type visual photographic Rick not some entry-level telescope incidentally should notice that even here with the air entry level telescopes the find objects for you is a sales pitch take that with a massive grain of salt there's a learning curve on all of these things but the easy scope they've partnered with the search for extraterrestrial intelligence they can get involved in searching for asteroids even the search for extraterrestrials if we saw an alien tonight I'd make my easy what we'd like is a networked system of cameras the sort of thing that you miss teller is planning on where we can go back and search through the raw data from one or many cameras you plan to aid in the search for extraterrestrial intelligence by using on the smallest and most limited telescopes on the planet with thousands of Eva scopes distributed all around the planet we'll be able to increase our knowledge in astronomy to be able to study asteroids comets supernovae and even this unknown astronomical events all the the unknown astronomical events are going to make first contact but for us for the rest of it what does any of that have to do with the search for extraterrestrial life with the visco contributing to science is simple and entertaining all you need to do is activate campaign mode on our app it will allow you to receive observation requests from scientists directly on your smartphone for instance you'll be able to see and track a near-earth asteroid while helping its study let's just call me ultra skeptical there's a load of astronomers out there who are really keen on the contribution from a citizen scientist with their toy level telescopes operated by people who know nothing about astronomy he knew from sight deeply unsuited to astronomy like say for instance the middle of Paris then transfer the coordinates to you evey scope have the touch of a finger and harvest data about an event all the while seeing it happening directly for VIPs but let's just give it to them for free that they can get some sort of parallax type measurement on near-earth objects really skeptical about that being possible with such a limited machine but whatever we'll give it to him for free with the Eva scope contributing to science is simple and entertaining do you know how boring this would be to watch through the eyepiece all the while seeing it happening directly through the eyepiece all asteroids appears star like in telescopes of any sites and further they move really slowly so you're gonna see through your telescope is the very slightest movement of a star over the period of hours it would be one of the most boring things to spend hours watching through a three thousand dollar telescope for instance you'd be able to see and track a near-earth asteroid while helping its study especially when there are already robotic telescopes you know just take this one example the 48-inch Sky Survey telescope at the Palomar Observatory hundreds of times the light-gathering of the Eevee scrape over a hundred times better resolution than the Eevee scope and it's situated in a dark sky site you know not operated by amateurs in Paris but one other thing that is critical to remember telescopes are almost always limited by the atmosphere if you live under somewhat murky skies you're wasting your time trying to see faint objects you'll just never get the contrast and they'll be lost in the murk all the Eevee scopes in the world won't change that and honestly if you live in a place that's murky or as bad light pollution which about half the places I've lived in in the world your only real option is planetary astronomy for that you don't need particularly clear skies but you do need this guy to be still and even here you're running to more or less the same limitations and the optimum size for a telescope is about eight inches and if the imperial units bug people well I'm sorry but telescope diameters are still mostly measured in inches four inches is small six will just about get the job done eight is where the sweet spot is and eleven is getting a bit big to handle but for those who desperately need it in Si eight inches is about 200 millimeters so you'll know where to start I would start with the eight inch Dobsonian learn your way around the sky it'll give you solid views of the planet four times as much light gathering and the better views of the planet for one sixth of the cost of the Evie scope if you got more cash honestly I've been fairly impressed with this thing as mount it's got a self-contained battery but no GPS it's got a fast and relatively quick single star alignment if you're willing to give it your location and time which makes it very good if you just want to go out and do some quick planetary observing now if your favourite planets long focal length is your friend so these are the max you have Casa cranes in three five and seven inches the central obstruction tends to be smaller which means they're better for planets it also means they have better resolution so this is a focal length of about 1.2 meters 1.5 meters this is a solid performer for a relatively mid-priced telescope this thing is getting up into specialized territory and it's got a three meter focal length which really does mean it it's a planet killer yes this thing is superb for planets and not so for this at all for everything else if you want Whitefield for seeing whole nebulas in the field of view that sort of thing short focal length is your friend the eight-inch schmidt-cassegrain has its flaws most notably the large central obstruction which which means you lose some of the light gathering capability of the telescope it also means it kind of messes up the potential resolution of the telescope for the best resolution of the telescope you need an unobstructed aperture just what you get with a refractors and so this is a six inch straight this is a neat instrument on a German equatorial mount it's not like it's eminently port for you know I've taken these things around the world this is a eating Schmidt on a you know proven altar house which is again really very light I could admit if I'm doing a sake I want versatility I would go for one of these now if we go up not the bigger than the eight we go up to the 11 inch the the sky colored then at this point they really do get very heavy and very difficult to move around that's really the largest telescope one guy can sensibly handle it's got great light gathering capability it's got almost 4 times the like hovering capability of that guy but it's also about four times as hard to move around if you're under mediocre skies and you want Portability and you want performance this is about where all the factors converge so why did I spend all of that money on this sky cannon especially when where I lived in America at the time we was kind of useless because the skies just weren't clear enough well that's true but the simple reality is when on vacation under the clear desert stars I had the time of my life this is pretty much a first for me as you can see the sun's pretty much full risen and so I had the telescope here doing the time-lapse or what I have to node2 Pater's right next to the moon or fairly close to it so I told the telescope to go find Jupiter for me yes he does so there you go that's Jupiter and the full light of day is Jupiter and the sky cannon costs about the same as the Evie scope there is no wealth no world at all where any astronomer with this salt would take an entry level one-trick pony like the Evie scope over a sky cannon I mean even the top of the range 8-inch version of this clock scene and about half of the price of the Evie scope with four times the optical performance but don't take my word for it there are people out there who take astronomy much more seriously than me people of the clear skies and much better astronomical setups people through my best efforts here would count this amateur hour you know big blurry stars slight field rotation and all that sort of thing and they hang out on forums like cloudy nights are you'll find the EB scope getting raked over the coals for very much the same reasons that I've went over here and asked for their ability to integrate all of this with the apps and all that sort of thing it's just say I'm skeptical about that too you know what would it currently being over a year late yeah I got one word for anyone trying to sell a 3,000 dollar telescope with the optical performance of a 300 dollar telescope all on the promise that it's going to be a hundred times more powerful than a regular telescope busted so I hope you enjoyed that and if you think you're getting into a Ronna me well i hope you found this video useful and below you'll find all the links to all the telescopes I went over in this video in my Amazon store below you know it's a horse costing less than three thousand dollars so if you enjoyed this video make sure you
