    Unlike capturing images with a camera, here the photons that left the astronomical object themselves are entering your eye and making contact with the retina! Really fascinating! Keep it up! Looking forward to more videos from you!

    I love your concept of trying to faithfully represent the image your incredible scope provides. Those last planet images show that you have taken the time to make sure each scope is individually collimated so the combination can act to its peak. The planet images also look they were nights of pretty good seeing.

      Thank you very much, Marc. 😊 Collimation of the binoscope isn't that difficult, as you can see in my other video, and the view with two eyes is actually impossible to render in an image, but I do my best. Strangely enough, seeing is a (very) little bit less of an issue with a binoscope because your brain gets to choose the best off 2 images, or at least that's my personal theory anyway. Cheers and clear skies to you!

    Well, I saw my first galaxy M51 through a 20 inch F5 in Dorset U.K. many years ago, I think it was a tiny bit brighter than your image. But I must say, you do give an honest representation, the truth is that even with a large telescope most objects are rather disappointing, at least visually. I suspect that even M31 in a 10 meter telescope if it was possible to observe visually is a sobering experience. Our eyes are just not up to the job. One last thing, I came across an astronomy magazine many years ago where an amateur used a 16inch scope and breathing oxygen to observe visually as deep as possible..... He did see a magnitude or two deeper than standard observers....

    • @astronomydrawings
      @astronomydrawings  Před 11 měsíci

      Pure oxygen dilates the pupils and gives a feeling of a "high", but I wouldn't recommend it to others. Yes, our eyes have been poorly made and even with a 10m telescope it wouldn't be all that impressive as such a scope would have a minimum power of 1429x for a 7mm exit pupil. Atmosphere and all... My binos are comparable to a 25" mono, but of course there's the factor of sky quality and the human eye. My sky certainly isn't perfect with an SQM of 20.9, but I don't complain. For most people telescope images are "disappointing" because all they know is the incredible, high-definition, million colour photographs. Of course, no visual telescope can ever compete to that. But when you explain that the photons that hit your retina really come from those far away places and have really travelled even for millions of light years to end up in your eye, people are generally astounded. Besides, I have yet to see a photo of the Orion Nebula, for instance, that's just as impressive as the sight through a big telescope under a dark sky. Or through a binoscope such as mine with its bewildering 3D effect and seemingly infinite FOV. 😊

    The other important thing to rememebr is that big telescopes are generally not for big objects. A 15" telescope, even at f4.5, is not going to give a great view of the Pleiades, for example, because it will be zoomed in too close.

    • @astronomydrawings

      "The best" is very subjective.

I'll never dispose of my 100mm binoculars either. 😊 Anyway, you don't have to win the lottery... a ticket to Northern Italy will do. 😆

    Thanks for video. That's a very nice binoscope and your sketches are excellent. For those with smaller scopes (or bigger scopes), dark skies at high elevation will make any telescope bigger. My best observing spot, by far, is New Mexico Skies. It's at 7400' elevation with dark & transparent skies. The views of the bright Messier Objects thru my 16" dob looked like the B&W photos in Stephen James O'Meara's book, "The Messier Objects". There are better observing sites but I haven't been to them yet.

      I'm in southern New Mexico as well. I belong to the local astronomy club founded back in the 1950s by Clyde Tombaugh and others. University of NM gifted the club a 16" Meade LX-200 they built an observatory for in a local park north of town in Bortle 3-4 skies. In town at the back of my apartment it is Bortle 6, but most light sources are blocked by my building and trees so it isn't as bad, but I can only view the sky from West by Southwest to the Northeast and Zenith. I'll set my 6" FF5 reflector up on my porch and just stargaze for a couple of hours. To say I know the Northwest skies fairly well would be an understatement.
      I'm only 10 minutes from B-4 skies and 30 minutes from /Bortle 2 next to one in White Sands Missile Range. The whole area is 4000 feet or higher, but if I want to camp out it is 90 miles to Bortle one NOT in the mountains, but in flat rolling hills at 5400 feet. Now if you're acclimated to high altitude I've been to the Ruidoso Ski Area at 10,000 feet and the stars are magnificent.

      So true. After being both fascinated and disappointed in the views from my8", and reading that aperture is everything, I thought I would get the biggest scope I could find and see colorful nebulae. Then I read that exit pupil is everything, and thought i'd get a big telescope and long eyepieces to get a huge exit pupil. Then I read that exit pupils larger than your eye pupil don't make the image any brighter and the image never gets brighter than you can see naked-eye. I was very disappointed but also glad I found out before I bought something huge that I couldn't handle.

    Curious, if you've had the chance to compare views of celestial objects (particularly Jupiter) from your 18" binoscope, side by side with a traditional 18" Dobsonian with similar quality optics. Would the 18" traditional Dobsonian's view be very similar? Or put another way - if you were to close one eye when using the binoscope, do you lose much - as it would be portrayed in your drawings? I guess one more way to ask this is - how big of a traditional Dobsonian would you speculate would have somewhat equal views (as expressed via your drawings) with the 18" binoscope, assuming all the optic qualities were similar?
    Many thanks for the information you shared via your channel! Excellent public service to humanity!

    • @astronomydrawings
      @astronomydrawings  Před rokem +2

      Thank you very much for the wonderful comments and the compliments about my drawings. In one of my other videos (about binocular summation) I've answered more or less all of your questions, but I'll summarise here. There's a significant difference between looking with one or with both eyes and it's an experience I have every time I put my eyepieces in focus because you have to do it one eyepiece at a time. Objects seem bigger, clearer and brighter. Details are much easier to see and the feeling of total immersion is beyond compare. Of course, an 18" binoscope retains the resolution of an 18" mono, but at 25arcsec this is 99,99% of the time limited by the atmosphere anyway. After years of comparisons, also with similar monocular scopes, I state that a binoscope yields the performance of a monocular scope twice the aperture, so an 18" bino is more or less equal to a 25" mono. Actually, possibly higher still because it's less likely that a false signal is accepted as true by both eyes simultaneously and... an 18" bino has the exit pupil of an 18" mono. Therefore it allows lower power with more light and you can see objects with a lower surface brightness than any monocular scope.
      I hope that this answers everything, if not please don't hesitate to write.
      Cheers and thanks again!

      Be careful what you wish for! If your scope's too big, forget about hauling it to a dark site and that's just as important as telescope size. Start with a decent pair of binoculars... you'd be amazed what you can already see with those! Clear skies to you!

    For me doing astrophotography is like googling for some images. If your not seeing the object with your eyes whats the point? I have to say i was a bit disappointed and misslead when I first bought my 12" because of all the images you can get with a camera, that has nothing to do with what you can actually see with your own eyes. Starting astronomy alone can be a real challenge. Thanks for staying true to what we can actually see!

      Well, astrophotography is an art in itself and I can understand that many people find great satisfaction from capturing these beautiful images. But, just like you, I prefer to see things with my own eyes, even if it's merely a glimpse of what a photo can show me. Thank you very much for your lovely comment! 😊

      The focuses are ordinary, see here: czcams.com/video/aweaNO2S9zk/video.html
      For the rest, the eyepieces are 22mm and 12 cm Naglers and 8mm and 4.5mm Delos for high power. For the nebulae, Baader OIII or Lumicon UHC filters were used just for the fainter details on the nebulae themselves, but without filters for the stars.

    I guess everybody has a definition of what is a REALLY BIG telescope, but I would say for most people 18inch is middle size, not really big. Big would be like 24-30 inch and REALLY BIG (with uppercase characters) would be above one meter. This being said, nice drawings. You should try M33 with a UHC filter.

    • @astronomydrawings
      @astronomydrawings  Před 2 lety +1

      Well, that's a matter of opinion. If you have a 25", an 18" would indeed seem "middle-sized", but for most astronomy enthusiasts I know 18" or more is still a dream and they often wonder how such a scope would compare to their 10"-14". Besides, mine's an 18" BINOscope so definitely not middle-sized! 😁 I was actually referring to amateur telescopes so you'll agree that there aren't many who have 30" or more. In fact, I have already observed M33 with filters, though I prefer without so you can clearly see the cluster within NGC604... 😆

      @@lowellmccormick6991 That's the thing. an 18inch which one has to move is really big. But that was not said, I just saw "REALLY BIG", and believed it was going to be about a much larger scope. Face it, 18inch is a good diameter for a secondary mirror (just kidding...). But in the absolute it's not that big. I have observed through really really big telescopes (above 2m diameter) and in fact for visual use they are in a way too much. You can see very nice colors, but the field of view is so small that you miss a lot (i.e. at 1000 times, M42 is just the small region around the trapezium), plus the images are blurry because of the seeing. Same for planets. A big telescope will always give more contrast and color than a small one, but when the seeing is 3 arc second, it's 3 arc second for everybody. But when it gets good, it gets really crazy. I'm lucky enough to be in a good site where I don't have to move my scopes and that's indeed a luxury most people can't afford.

    How does Uranus, Neptune, Pluto look with these super mega binoculars?

    • @astronomydrawings
      @astronomydrawings  Před 2 lety

      Uranus and Neptune look like tiny little disks, Uranus more turquoise whereas Neptune appears smaller and more bluish. I believe to have seen a hint of a darker band on Uranus, but it's hard to tell: www.astronomydrawings.com/Planetary/index.html
      Uranus shows 4 or 5 of moons whereas Neptune's big moon Triton's clearly visible, also in small scopes.
      Pluto (mag. 14), on the other hand, is just a tiny star which is indistinguishable from the other smallest stars in the field of view. You may get lucky when Pluto happens to pass near a distinct asterism, making identification possible, or you need to look again the next day and see which of those tiny stars has moved. 😊

Of course, this isn't exceptional and you can do just that with much smaller monocular scopes, albeit with a more limited resolution.
      The Moon actually isn't the right object to compare telescope size as it is so bright and telescope power and resolution are in this case more limited by the atmosphere than by telescope size.

    Each to their own. So long as you enjoy what you're doing, who cares! The disappointing drawing for me was M42, the Great Orion Nebula. This is a naked eye object, literally the brightest nebula in the northern hemisphere. I thought you would have seen more? Bigger is not always better. As an imager I can get beater results with small telescopes due to the longer integration time of the ccd camera. However, their is nothing more visceral than looking through a telescope and seeing the planets, especially Jupiter and Saturn , so I can see the appeal.

      Of course, not even the biggest telescope in the World could compete against photos with hours of exposure time. The joy of visual observation, compared to photos, is that you've seen it yourself with your own eyes, rather than on a computer screen after many hours of fiddling to get the image right. Then again, I wonder, how much does my impression of the Orion Nebula differ from a photo, apart from the absence of colours other than blue/green? 😆 But, as I said, I didn't want to exaggerate either and my sky is only SQM 21.00.
