Hey Geezer, I’ve got a question.
Could you shoot NV through LRGB filters and process them into a color photo, like they do with monochrome cameras?
I suppose that is possible, but would require a dedicated camera and computer programs... that I do not have, nor do I know how to use... and honestly, have no desire to acquire or use. Someone else will need to pick up that mantle. I use NV and phonetography to capture images which largely take the place of my notes. But, as I explained above, the phone images now surpass what I can see at the eyepiece of my NV device.
I am a visual observer at heart and never anticipated that I would enjoy this simple technique of AP so much. I like NV Phonetograpy because it IS simple and does not intrude on visual observing. I should add that stellar points of light are no problem for NV, so splitting close doubles and taking images of globs and open clusters is the easiest of all the astro subjects. And, of course, taking excellent images of Luna, Jupiter and Saturn without NV has already been demonstrated by others here. But NV allows the phone and scope to reach farther and deeper, and without resorting to ever increasing aperture which became a burden to me. If all of my astro equipment was stolen tonight, my NVD would be the first thing I'd replace.
Since NV is more productive with a faster focal ratio scope, I recently purchased an ASA (Kellor) reducer for use with a 6" f:4 Orion Newt... allowing it to perform at f:2.8 with a wider FoV. But I intend to purchase either a C8 Cat with a 6.3x reducer or an 8" f:4 Newt for a little more focal length to improve images of the smaller subjects like planetary nebulae and galaxies. Although I can image them now with my phone+NV, the results are marginal, except for the largest/brightest like Sombrero. Below are some examples (not in my gallery), all taken with iPhone 6+:
Sombrero seems bright enough taken through 140 refractor @2x, w/iPhone 6+ ISO 500, 1/2s for 15s, cropped and compressed to fit here
M-51 Whirlpool also seems bright enough, 140 @2x, 6+, ISO 320, 1/2s for 20s
M100 as a face-on with lower surface brightness is a little too dim using the smaller apertures with short focal lengths. This image taken with the ST 120 is quite noisy, taken at ISO 64 1/2s for 20s. Taking a second image, I would increase the ISO for greater sensitivity, but using a longer FL for better scale would help most.
These last two images show how the longer focal length helps on M33 Triangulum, the first was taken with the ST 120 at 2x which means the FR was f:10, ISO 32 1/2s for 20s. The second was with a borrowed 8" Newt at 2x (f:7.8), ISO 125 1/3s for 10s... mainly, the scale is much better and IF I had used higher ISO, the subject might have displayed better detail. But I like to keep the sky background dark, the way I see it through standard glass eyepieces, so normally I keep the ISO pretty low... which also helps to reduce noise.
