I have experienced an APM 100mm bino-telescope, but with glass eyepieces. In my limited experience, bino-telescopes excel at providing a relaxed view, with both eyes open, while providing a brighter combined image than a single scope of equal aperture. And a bino-scope image sometimes looks 3-dimensional. With two NVDs, it is easy for me to imagine why Gavster chooses this system as his current favorite. It's not as bulky as a larger Newt and provides the sharp stars of a refractor. There isn't much to dislike about that system. Gavster and I communicate often to discuss discoveries and equipment, so his favoritism is not surprising.
I don't think I can claim either a best or a favorite setup for my Mod 3C NVD; every optical system I have used has offered something different. None of my optics offer a huge aperture because I almost always travel to an observing site. My red-zone home is not really pleasing; limited sky access, numerous street lights, neighbors' yard lights, another neighbor's little dogs yapping at me for being in the alley at night, etc. By choice, I have kept apertures smaller for portability... because 40 miles away and 800' higher, is a green zone that offers pretty nice views of the sky with the only sounds coming from distant cow bells or the song of coyotes, which I enjoy. BUT, my main emphasis is not visual observing; the vast majority of my time is spent with my phone attached to my NVD, taking short exposure images.
I take NV images to see more, and see it better. My phone with NightCap camera app, pretty much eliminates the noise I see visually when using H-a filters; for me this is of great benefit. Declining eyesight with age related issues have brought me to this solution. Since about 2018, I have used 3 or 4 camera lenses and an 8" Newt. The camera lenses provide 2x, 4-5x & 11x to show how things fit together in the sky. The 8" Newt serves to provide a good reduced, native or barlowed image from ~22x to 60x, with a smaller FoV.
IC 1396 is a very large cloud of H-a that also contains several Barnard dark nebulae. But IC 1396 is not an isolated nebula. It resides in a huge cloud of much less dense H-a that is not documented on most charts. Below are three photos at different scale. The first is with an 8" Newt w/2x Barlow of the Elephant's Trunk inside IC 1396. The second image is with a 300mm lens which is marked to show most of the Barnard objects in IC 1396. Last, is a much larger swath of sky that does reveal some of the faint H-a that surrounds IC 1396. They each serve to show a different aspect of this much photographed nebula. The H-a filters used for these images include a 12nm and 7nm for different subject matter with different needs through different optics. I look at H-a filtration differently than I did 3 or 4 years ago. They are all useful in prime phonetography, but some are more useful than others, depending on sky conditions. And I see my 3.5nm filter as a specialty filter, rather than a general use filter like Gavster, who's equipment is optimized for afocal use.
I have been fortunate to use my NVD in a variety of other optics when observing with friends. Some have even loaned me their scopes for the night! Although it is amazing to see the advantages of using NV in a fast, 20" goto Dob, the disadvantage of cost or storing and moving that scope, make it unrealistic for me. There are always tradeoffs and limits. So the old adage still rings true, "The best scope is the one you use."
IC 1396 - Elephant Trunk, taken with 8" Newt with 2x Barlow + 12nm filter, ISO 6400, 1/3s averaged 10s
IC 1396 taken with 300mm lens + 7nm filter, ISO 6400, 1/4s averaged 15s
IC 1396 taken with 105mm lens + 7nm filter, ISO 5000, 1/10s averaged 10s
Here's another good example of how scale changes the appearance of M31. The first image was taken with the 8" Newt, ISO 200, 1/5s averaged 10s. It reveals the core and double rings of the galaxy quite well. But the second image, taken with a 300mm lens, shows the galaxy's extent much better, taken at ISO 320, 1/6s averaged 15s. To me, one system was not better than the other... just different.
I was always amazed at the detail shown in NV photos taken by CNer jdbastro who uses some great (and diverse) optics. Images in his gallery are the absolute best NV images available. Although phonetography has come a long way in the last 4-5 years, it still has a ways to go! I'll keep at it though, as long as I'm able.
