Those views are amazing. It makes me long for NV!
Man, if you’re considering an SCT and fast F ratio is important, you should seek out one of the old Meade LX-200 10” scopes that were offered at F/6.3! I’ll bet that thing paired with NV would let you see the Big Bang from NYC!
LOL! Well, not quite. NV does have it's limitations. But for amateur astronomy it certainly opens windows of opportunity. And, in H-a, NV reveals some things that any amateur scope using a glass eyepiece cannot see at all in real time... things that are otherwise only seen in long exposure AP. To see the size of Barnard's Loop and the Angel Fish together in Orion real time can take your breath away. The other really wonderful attribute of NV is that it gives a wholly different perspective of how our galaxy is put together... how and where things fit. I say this because at 1x we see a 40° circle of sky, which is big enough to show the N. American, Pelican, Gamma Cygni, Veil and Crescent Nebular complex in a single FoV. When I look S. in the summer toward the center of our galaxy and scan the Milky Way, I see a vast ocean of nebulae, seemingly all connected. What I always thought were small, individual nebula often are not... nebulosity connects vast fields of H-a within our M.W... and I am fortunate enough to see it in real time observing. As an example, the image below was taken using an old 50mm Nikon as a prime lens at f:1.4 attached to my NVD with a 7nm H-a filter, ISO 80, 1/2s for 8s. This image is at 2x and encompasses 20° of sky. All of that cloudy appearance in the image is H-a. The N. American and Pelican are often imaged in this complex, but look how vast the complex really is! Seeing this makes it easier to understand where sufficient quantity of Hydrogen exists to coalesce into stars... it's a visceral kind of astronomy experience.
And, to keep this post on topic, the image was taken with my iPhone 6+ which had only an 8mp sensor. My XR has a 12mp sensor and slightly better low light capability. IIRC, the Huawei P20 has a 20mp sensor! Let me repeat, phone camera capability is only getting better!
