I've been scouring the web for the answer to my question, but I feel the only way to get a good answer is to ask the wonderful people of CN. I bought a Meade LXD-75 SN8 about 2 years ago (not knowing anything about what to buy) and since then have grown more and more fond of deep-sky astrophotography. I built my own observatory, upgraded to a moonlit focuses, got a modified camera and upgraded my mount to a Losmandy Gemini II. I still am disappointed with my photos though. My stars are never round on the edges, my telescope won't seem to stay collimated and I feel like my corrector plate is misaligned...
My question is this: I have a bit of money that I would like to sink into really getting myself setup for a few years of happy deep-sky astrophotography. I would like to get what I need to allow myself to get the beautiful images I keep seeing all of you posting. Would it be smart to upgrade my telescope? I was thinking of an ES102mm APO or maybe an ES80mm APO? Or the much cheaper ES152 Achromatic?
I have about $1500 to $2000 to work with. Is this a smart upgrade, or should I spend the money trying to get my current telescope to work? I know the answer might just be that I need more time to practice, and I totally would understand that as well. It's just looking around on AstroBin there are very few images taken with a Meade SN8.
Thanks for all of your help!
