Still Wow! I just bought a used LX200 8" GPS like new. Cloudy and rainy here with no chance to look. I was thinking about getting that Celestron 5MP camera and see what it would do with a DSO. If I could get an image like that second one I would be satisfied! I have Adobe Creative Suite subscription and could process it in Photoshop.I believe I could do that.
You're headed for a difficult road. The two chief beginner mistakes are an inadequate mount, and too big a scope. The LX200 8 inch, unfortunately, qualifies on both points.
Look at Pauls72 icon image. That's the "hot setup" a good equatorial mount and a small refractor. If your goal is to take images like his, that's the path to go down.
A good solution is to forget the big scope, and start out with a camera and a lens. This excellent book will guide you through the process. It starts out with a camera and a lens on a tripod, then on a camera tracker (which can be DIY or store bought), and then to a small scope on a good mount. Scroll down the webpage to the picture of the author. That's a 70mm refractor (about $500) on a Sirius mount ($1200). You spend more on the mount than the scope, it's more important.
That's a lot of money, so the camera/lens approach is my recommendation. It will both be excellent learning, and a way to figure out just how far you want to go with this.
The mount is the key. A bigger scope is not better for getting into this, it's (far) worse. Long exposure imaging of DSOs is nothing at all like visual astronomy.
