I've fortunately gotten better at imaging this year by leaps and bounds with my ES ED80 FCD100. Right now I'm making very satisfying images finally that I'm continuing to learn how to process better. I use ASIAir Pro along with guiding and electronic focus and everything is working well. I am interested in a counterpart to my widefield scope (I *really* don't intend to have more than 2 scopes at a time) as my next "big" purchase either this fall or spring of next year so I am curious what everyone's thoughts are. As for my widefield setup I don't intend to upgrade my ED80 for a few years, but I do wish it had a tiny bit more focal range and that I could get slightly more of a flatter field (I've done my best and about 90% of the image is flat now) so maybe a few years down the line something like a SkyWatcher Esprit 100 APO is in the cards.
I'm thinking Celestron EdgeHD 8 with the .7 reducer and an OAG. The focal length will obviously be significantly more that my ED80, with an OAG it should prove to work well with my iOptron CEM40 mount (I have an ZWO 174MM Mini ideal for SCT OAG guiding) and I'll certainly be able to hook it to a laptop for avi capture and planetary work too. I started in all this 5 years ago with a C8 SCT that I don't have anymore and I have a soft spot for the SCT design but I know like everything it has compromises. Do you think going to an SCT is the right choice? 480mm on my ED80 f/6, 1422mm on an EdgeHD f/7 with .7 reducer, 2032mm on the EdgeHD f/10 with no reducer for planetary. That should give a nice blend that lets me do everything from widefield DSO to galaxies and globular clusters to planets right?
Any other ideas for a 2nd scope that isn't an SCT and would work with my existing CEM40 mount? Thanks!
