Hello all. I recently purchased this 18" "Obsession Clone" on Cloudy Nights. It's my dream scope, and a big upgrade from my 12" (had to drive to Phoenix from LA to get it). I bought it from the second owner, who said the original owner constructed it in the 90s. I have Bortle 9 skies, so it's mostly been lunar viewing from my home. I've gotten to take it to a Bortle 2 and a 3 site since I've had it (2.5 and 3.5 hour drives). The views of DSOs out there are phenomenal, but I won't get into that, since this is not an observing forum.
I would like to ask the community for any advice you might have, things to watch out for, mistakes I might make, and recommendations you might have. For instance, I caught it slowly dipping downward at my dark site when I had a heavy eyepiece in it and was pointing it low (~25° above the horizon). I think I narrowly avoided disaster on that one! Simply put, this is a lot of scope, and it makes me feel like I could make a wrong move and cause severe damage. I already damaged the rocker box by trying to load it into a van by rolling it up a wheelchair ramp, when "something got caught on something" and somehow damaged the wood.
As for equipment/accesories, what do you suggest I add? I have a 35mm Panoptic, a 38mm Q70, a 24mm ES 82°, a 14mm ES 82°, and a 7mm Delite, plus a 2" Barlow. I got a Glatter collimator with purchase of the scope (love it!).
I have a few filters (variable polarizing moon filter, 2" Baader Contrast Booster (love it), 2" Orion Ultrablock (don't care for it!), and just got a DGM NPB filter (haven't used it yet). At f/4.5, I do notice some coma, especially at lower powers, but it's not too bad. Do you recommend a coma corrector, and if you do which one do you use/like? I haven't been able to get the NGC MAX to work, as the encoders seem to have trouble working... That's something I need to work on. A light shroud is coming this week.
Thank you in advance to anyone who has advice. I haven't posted much on CN, but I am an avid reader of your forums!
