I found this thread BeeBoping around CN Night Vision Astronomy Topics. Thank you for starting it it has been useful. I agree about the SCT's, I had pretty much discontinued the use of my C8 Edge HD and it had been sitting around for a long time. Night Vision Astronomy is one thing that this scope is really good at and I to, am very glad that I had not sold the C8 off. One ironic thing about this Astro Hobby I have experienced that at sometimes the antithesis of what should be true, works marvelously well, bringing interesting surprises.
HAPPY SKIES AND KEEP LOOKING UP Jethro
Right on. Maybe we can get more tips going. Some people seem to disagree on focal length, but it only makes sense that it will zoom in. And shorter focal length scopes will show larger objects. There are some really big nebulas out there where a short focal length is useful.
I remember in posts many years ago people touting having multiple telescopes of different types is useful with night vision.
For globular clusters in light pollution it's quite helpful. I tend to not use any filters with the 8 inch SCT. It's always worth considering unfiltered as it can be the best view.
For the 8 inch to be good for nebulas, the 55mm with 67mm adapter afocal would be best. Getting it to F4 equivalent. I've not had a chance to try this yet, but I'm interested.
