$3000 of eVscope tears vs REALITY!

so let's take a look have the t's of unfathomable sorrow coming from the Evie scope packets these are people who paid about three thousand dollars for a telescope there it can be sort of matched by something that'll cost about $500 all these heaters are only jealous of people who are interested in astronomy and the possibility to see beautiful celestial objects without spending a huge amount of money and time think $3,000 counts as a huge amount of money for most astronomers expert training installation and post-processing and now about that let's see what we can do with something that cost less than a thousand dollars cool as you see this one of the most full flight polluted areas ever this seems going to take a 10 second exposure or the telescope and the way it's gonna do it is it's going to give me a full second countdown so I gotta be really still wondering this okay so full one two and the reason are gonna be really still is any vibration whatsoever will shake the telescope today give it four seconds to sort of stop shaking the telescope and there we got a house at 10:00 the second exposure on the Orion Nebula looked like it's yeah not so bad really yes everything's human I bet on that you know they run their bill 10 seconds of that's what you can get out of 20 seconds with an absolutely nothing special setup geez look the EB scope will work 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 it's a brand new never thought of before method of using a long exposure to get a picture capable of accumulating light in a unique way so we could finally see those nebulae those galaxies all in a matter of seconds and directly through its lens I mean no one will ever be able to do that especially under murky bad light polluted guys from within a city oh well I'm sure this is gonna be well received by the EB scape back is that Thunderfoot video is seriously hilarious the amount of mistakes assumptions and flawed arguments he presents his too funny I wouldn't worry about him or his followers nurdrage looks impressive but it's really just that nerd rage yes I'm so dumb I just do we have a clue making so many mistakes it's laughable can't name any of course but there are so many mistakes and Betty is not even a real scientist oh but it gets better there's a reply that I'm jeanna clean challenge buffoon could use a good hosing down as well from another Eevee scope super backer again I'm not really seeing much there in the way of an argument you know challenging anything that I actually said all coming down the Eevee scope will have to prove itself over time citizen scientists initiative will open doors to far more beginners than pompous boastings whilst surrounded by a hundred grand in astrophotography equipment arguing about who is the bigger focal point or you know all things that actual astronomers might care about but yeah if my gear was as overpriced as the Eevee scope you know basically adding is 0-1 to the price then yeah you might pay a hundred grand for this Ethan reality in non massively overpriced Eevee Skoglund everything here the sky cannon cost about $3,000 the big refractor and the mount maybe two and a half the six-inch Schmidt and the mount was about a thousand the 8 inch Schmidt I cut years ago second hand so yeah nowhere near a hundred grand and of course barely any of this was touched on in the original video so I'm not sure how you got to boasting about this simultaneously I'm some washed poor foon who doesn't know anything about what he's talking about and he's a braggart with a hundred thousand dollars worth of equipment not really I mean if I were this bracket that he seems to think that I am I might have mentioned my most expensive telescope the h-alpha telesco it does one thing it looks at this Sun and as made appearances in several of my videos why wasn't that mentioned here well there was no point what the video is essentially responding to it massively overpriced cheap deep-sky photographic platform masquerading as some brilliant new way to do astronomy yep but the large part I don't emphasize how much the kit costs because that not the focus of the video it's about showing what it can do what it can show you and now yeah I can afford to spend thousands of dollars on a telescope to show people say for instance the surface of the Sun and it got to thank people who support this channel through patreon for enabling that it wasn't always that way I bought my first decent telescope because I got out there and delivered newspapers till I could afford it then and this is legit I worked at McDonald's till I could afford this thing and honestly if I was looking about bragging about anything it wouldn't be the cost of the kit it would be the dedication that went into making some of these videos I mean most of the time and you'd gloss over it because like I was saying he doesn't greatly matter but if you wanted to remake just that last video he would take months I would just take for instance the full rotation of Jupiter it took me half a dozen attempts to actually sort of get on the right page with that each one requiring a whole night of observing and another day after that to actually process the video to get something sensible out of it and each one of those was kind of a Hail Mary because even if the atmosphere was stable at the beginning of the night he didn't know it was gonna be like that for the rest of the night I'm watching the movement of Uranus over a night boom another night gone and another day for the processing the transit of Venus I traveled halfway around the world with a couple of telescopes to record the date from at least another couple of days to process it the solar flares and prominences I can do that I'd never done anything like this took me several days just to work out what the hell I was doing and once I worked out what I was doing you have to wait till the bottom decent prominences which could be anytime and you needed several days of continuous good observing to watch the movement of the prominences across the Sun you know that's ignoring the ones that you can see moving over the period of minutes to hours and the one that probably takes the biscuit yeah for the sheer amount of effort that went into you know like a seven second video or something was the time-lapse of the supernova each one of those images took the best part of a night to record most of the time freezing my ass off fighting off the desire to sleep because when you're on vacation it's a complete nightmare all of the day you're out in the open under the bright sunlight so when the sun goes down you feel you've just got to go to sleep and it's torment to fight against it oh yeah and while on vacation fun fact the telescope cost more than the car currently New York I'm gonna be following a Setting Sun with my telescope and various other stuff to the Pacific in the car we have planes more planes ah a camera that's gonna be doing the time-lapse for us oh I didn't do all of this simply so a decade or so later I could call [ __ ] on some scam hit line about a hundred times better than a classical telescope but sure over the years I've acquired quite a lot of telescopes now you may have noticed in my last video I didn't actually go out and use them why because where I currently live is in the middle of a heavily light polluted city with murky skies pretty much their worst conditions for deep sky photography buff fight let's go out and see what these things can actually do under these sorts of skies so hopefully later tonight on that mount there you have me to get driving once I don't see some stars I'm going to a side-by-side comparison of all these telescopes just using a standard digital SLR camera and see how all these boys compare so two things that you so care about if you're photographing faint objects the first most important one is aperture so in terms of aperture this one is 3 1/2 inches through and half inches 5 inches 6 inches subbranches 8 inches or in terms of millimeters it's 90 90 120 550 Elgort 170 or something in 200 that the earth square that basically gives you the light gathering capability these things the other thing you care about is the field of view and for that the shorter the focal length the bigger the field of view so this thing has by a way the shortest focal and it's like half a meter focalin from that point six meters or something and that's where a frak there's no central obstruction on that this thing is about 1.2 meters on the focal length so at all it's the focal length of that thing and I said max it off tend to have long focal length so that's about 1.5 meters 1.5 months MIT this thing is a beast this is the seven-inch man suit of that's about three meter protons than that and the eight inch net is about two meters so in terms of focal length that's three meters that's point six meters focal length of that thing is five times the focal length of that thing which means that's got a nice wide feel to it this thing is much narrower field so hopefully disguise hole and then they're always fairly murky here so yeah this is almost as good as it gets so what do we have we got a three and a half inch mag suit off which was used for the transit of Venus and a five inch back shut off which was used for the 2017 total solar eclipse the six-inch schmidt-cassegrain came with the mount which was used for mounting all of the telescopes here in turn and a seven inch mark suit off which I recently got cause it's coming up to ten years since I first did the whole rotation of Jupiter over a single night video now why is that significant I hear you ask well ten years is about how many earth years it takes for Jupiter to go around the Sun once that and that turns out that that's basically the point where Jupiter rises at sunset and sets at sunrise in summertime when you might be on vacation so basically I want to revisit the time lapse of Jupiter thing but with updated kit and that's why there was a big-ass refractor in that last video because I want to see what's the best piece of kit for doing this the 8 inch mitt there is the one that I got from working in McDonald's some 30 years ago and on the back end of all of these I'm gonna have the same digital SLR camera Pat it no specialized kid at all now it looks like they don't make these cameras anymore theft they're that old you is about 10 years old this thing there only important feature that you need is the ability to live you the sensor so one thing you will absolutely need if you're gonna play this game is a camera which is life you otherwise you're focused stars and focusing without the life you just takes forever oops sorry you need one of these cameras that allows you to look directly at the sensor this is a Canon 70d which is actually pretty decent with this sort of thing and nice focus on the stars that's not bad the flip screen is also immensely helpful now you can pick these things up on eBay for a few hundred dollars now I don't know where how these cameras have evolved over the years but cameras like this are still in the simplest ways to get into deep sky photography after this you need specialized care now the starting price for that specialised kit is going to be similar but for this video I wanted something where all you had to do was push a single button and get a deep sky image at the end of it there we go that's the trapezium that's the heart of the Orion Nebula on a live view through the camera so what I'm gonna do now is I'm just gonna push the button you see what I mean just touching the toe sketch sketch around loads I'm just gonna hold the button now see what we go okay so gonna hold it down for one two three four seconds and let's see what that looks like when we take a look at the image okay so that's what four seconds on Iran Nebula looks like in start but just start seeing the ability coming out now modern specialized kit is much better more expensive you know big sensor fairly sensitive and all that sort of thing but you need a computer to run it or if you were really keen and I might yet do this you could get the exact same camera the Eevee scope it costs about $200 but of course you would need a computer to run it and I just wanted this single push button version now on the digital SLR you get this thing called film speed which is basically how sensitive the pixels are to light the more sensitive are the noisier they get so the film speed here the ISO will go up to about 10,000 on this thing but in this case I scroll it all the way down to about 1600 then I took a 4 8 16 and 32 second exposure so you see how the different focal lengths and apertures affect what you'll see now there is nothing fancy with these images they just 1/2 minute exposures under some of the worst astronomical conditions that you might get now I could have put a light pollution filter in here which would have improved it some but I choose not to the reasons I'll come to later and also whilst I was doing all of this I looked through all of these telescopes to optically compare them the only one that was conspicuously underpowered was the three and a half inch max Uthoff this really just couldn't hack anything but the brightest deep sky objects it's actually pretty good for the moon and not so bad for the planet and of course it's very cheap and very portable costing about 200 or so dollars the 5-inch backsheet off is about 370 dollars the 6-inch meant these are the new prices by the way is about 550 dollars the 8 inch mitt if you were to get one new is about 880 dollars all actually gave fairly comparable views under this order sky why would deep sky objects you're looking at things with the low surface brightness and if the sky brightness is the same as the brightness of the object that you're looking at it just washes out completely all you see is the sky glow now both of the schmitz were clearly out of collimation not terribly so but enough to look optically worse than the mac suit I was basically with the Mac suit offs you start with the outer focus rings and then you focus them down to dots and you get the diffraction rings around them that's what good optics should look like the Smiths were sort of being squashed rings that didn't focus down to dots or not as nice dots with no obvious diffraction to my knowledge and this probably goes back to these or general design of the telescopes maxi tops were first introduced in military roles because of their robust nature but they were after time very expensive to make compared to the Schmidt's now things have moved on and they're comparable in price to the Schmidt's the six-inch Schmidt and got brand-new and the had the worst collimation and I really didn't have time to go through and collimate all the telescopes the 8-inch Schmidt hasn't been collimated for at least ten years and was somewhat out of collimation the 5 and the 7 inch maxi tops were bought new have never been collimated and both gave very good optical images so the seven-inch man shoot off here was about $1,300 and the three now Finch refractor I took it a long time ago cost about one and a half thousand dollars now these are beasts at the opposite end of the astronomical spectrum both clearly with the best optical performance here although optically the 5-inch match it off was also very good both focus straight down to point stars with diffraction patterns are a sign of good world collimated optics the three and a half inch refractor here is a Tripler basically a color corrected refractor which makes it much more expensive crazy expensive but optically beautiful it also has a very short focal length that means wide field of view so you get a big area of the sky and you focus all of that light onto the same sized pixels as a long focal length telescope takes all the photons from a smaller area of the sky and focuses them onto the same number of pixels this makes the short focal length refractor fantastic for big objects buddies conspicuously bad for planets they just appear too small in fact it has to work super hard to keep up with the 5-inch Mac suit off which is about a quarter of the cost of the refractor the Big Mac suit off was optically beautiful but has a tiny field of view which means that it kind of misses the mark for deep sky objects but it's fantastic for planets so how do all of these things compared with say the Orion Nebula want the biggest brightest and most speck kela nebula in the sky while in the first instance I just set up the mount and that took about ten minutes you basically put a telescope on there align it with three bright stars and it will track whatever you tell it to track now for me I really don't like the fact that once these things are aligned you can't undo the clutches and point it at whatever you want they don't have any coders on the access that means you've actually got to tell the telescope would you want to go and find and the scroll around and find it for you now I've never been greatly impressed by the menus on any go to mounts but I've always been impressed after they've been aligned how well they do the tracking now for this test none that greatly matters the only thing that you want the mounted to is to accurately track an object for about thirty seconds down this mount always great for that so let's start off with the bottom of the barrel a two hundred dollar telescope and we'll take a look at a fall and eight a 16 and a thirty two second exposure well okay you can see some nebulosity by the end there so let's now replace that with a five-inch scope and instantly we're comparable with the evie scope you know once you factor in that the evie scope exposure was four times as long it's the one that I'm using here and considering this is under horrendous astronomical conditions without even trying and I'm getting photographs that are comparable to the e V scope which costs three times as much all with a single push of a button and of course it's remind ourselves how AV scope markets itself a hundred times more powerful than a classical telescope sorry boys that's just got scam written all over it in a hundred foot tall letters and now we have the 67 and the eight-inch scope cool so now let's take a look at how this looks through the short focal length wide field refractor now he see that the image merge up due to the sky Clos amazingly quickly but this kind of shows you the limits for the telescope you will never be able to see nebulosity fainter than the sky guy well not entirely true if Scot glue is only from sodium streetlights you can actually filter out a lot of it but ya can't get rid of all of it and sadly now many of the streetlights are being replaced with LEDs and there is no way to filter those out so I left it in there so you can see under the skates where you can only see the brightest stars and a city with light pollution or you might expect to be able to see now none of this of course would matter if you're looking at small bright objects like planets there you really don't care how murky or light polluted it is as long as the atmosphere is still in fact frequently the best planetary conditions are under a slight fog because typically fall currently starts to form when the atmosphere is very still but anyway let's do a side-by-side comparison of all of these images with no processing nothing just the raw images from the camera simply push-button photography so in the city you clearly run into the wall for deep sky objects at about five inches of aperture and Donald skies though this would be a very different game their aperture would win because the sky won't be a glowy mess after 30 seconds now of course you can play this exact same game with the Eevee scope so this for instance was their picture of two minutes on the Orion Nebula undisguised that would clearly better than mine that's what the Eevee scope does cool and this is what the sky cannon could do with 20 seconds at a dark sky site just by pushing a single button on a digital SLR but this highlights another problem with Astro photography a intrinsic one this isn't a criticism of the Eevee scope you're trying to display on a picture things that vary in brightness by thousands of times so if you want to show the structure on the faint nebulosity you tend to burn out the center and if you want to see the structure on the Braith nebulosity then the fainter nebulosity simply appears as black of course you can't mess around a little with photoshop and so I can just simply diddle with the brightness and contrast on this image taken by a 30-second exposure with a five inch telescope and it goes from this to this and now let's see how that compares to two minutes on the Eevee scope under good skies capable of accumulating light in a unique way so we could finally see those nebulae those galaxies all in a matter of seconds and just in case you missed it earlier all of this was done with a single push of a button cool out here on another very similar night and a slightly different sort of on the telescope this time I've got a the camera which is a very small sensor it's meant for planetary photography which is why you're gonna get a terribly small field of view here but this is just to give you an idea of what this could do and so at the moment that's actually this other live view from the camera that's down a quarter second exposure so as I tap the telescope you'll see it's all shakes around a bit and so what I'm gonna do it's gonna check that out too from a quarter of a second - that's a second and even at that as a one-house second exposure you starting to see the nebulosity dial down the gain a bit done the gain a lot and now I'm gonna dial up to three second exposure yeah it's a three second exposure and let's go up four fifteen second exposure or something and so you can your versions of software like this sort of that just roll it in real time so you see there's some pretty decent views of the middle of a nebula from a pretty light polluted sky from you know this is a this is the couple hundred dollar telescope the camera here is actually moderately expensive but that's just because it's the plug free camera that I had you know you get things that would do something like this for ya probably a hundred bucks or something cool so a big sensor is typically what you want for deep sky and digital SLRs are not a bad way of getting that for planetary not so necessary now for the mounts with a decent telescope manufacturer you have an understanding what you're paying for is gonna be fit for purpose historically of being super skeptical of these one arm mounts as being way too shaky but I actually this thing's pretty good even with a heavy telescope but even here when you get into the smart devices I've had nothing but trouble trying to use it if I line it from the handset then they works fine and it's fit for purpose but when I try to do it from the app firstly it loses the connection with the telescope on a regular basis and won't reconnect which is simply dumb and even when it does reconnect the scope actually thinks that it's tracking one object all the app thinks that the telescope is pointing that's something completely different I really don't know what's going wrong there whether it's getting the GPS and location date from the phone or something and if that's wrong well that throws the whole alignment out or whatever but I'm far from the only person to have this sort of problem also trying to slough the telescope from the push buttons on the handset is super easy I have four buttons that I can easily feel in the dark even when my eye is up to the eyepiece trying to do this from a smartphone is almost impossible because you get new tactile feedback from the my phone you can't tell when you're pushing the buttons unless of course you take your eye away from the IPS to look at the smartphone which obviously makes looking through the eyepiece and tracking stuff harder put simply these are keen push-button cursors are actually a much by the way of controlling the telescope then a smooth featureless screen like this so where am I going with all of this yeah if it works it would be nice the thing is that even if all of this smart stuff he set a dead loss it's in this case it kind of is I don't care because the mount is physically solid and it tracks well all of that you can do with the handset you don't need any smart device and it gets the job done and even if all of it fails I still have a nice telescope to look through problem is if you have any trouble like this with the e V scope it's completely useless at least the device will Auto align you to $3,000 paperweight now even though the evey scope is over a year late at the moment apparently the first deliveries a chance debark coming through and the first tweets about it are coming through featuring such great hits as my TV scope won't align or what do I do now and we're actually getting some pictures from people using their actually V scopes why is impressive as the PR shots featuring and collimated telescopes those star images are Menna be nice point sources well what's good about that now also featuring out-of-focus images super greeny images and super over pushed images think you might have pushed the contrast on that one up a little high and none of it seems to quite compare to a sky cannon after 20 seconds of pushing a single button so much for a hundred times more powerful than a classical telescope now I'm probably the best argument for the Eevee scope is using it for outreach but sure if this is the case you would be better off with two or three telescopes like this from reputable manufacturers whether almost guaranteed to work rather than buying one TV scope like this so I hope you found the comparison of the performance all these telescopes interesting and how almost always the limiting factor of a telescope isn't actually the telescope itself but this sky that it's under there as some that maybe take too hard before committing to spending a few hundred dollars on a telescope and certainly something to take to heart before spending thousands and this ever if you found this video interesting and don't want to miss out on more
