Hi martin. No question is too small. I owe all my progress from the input of others on this forum. an 8" scope has excellent resolving power and is more than up to the challenge. the 224MC is a powerhouse of a camera
Depending on your local seeing, will determine your barlowing. If good, you can push the magnification. I use a Vivitar 3x or 2x teleconverter with m42 threads. On Amazon i see 2x, but on ebay the 3X model can be found. I use an sct to t-thread adapter. Then I screw in the teleconverter and then the camera. For 3x it becomes f27, and 2x teleconverter becomes f15. In the pic is the train. Add and remove spacers at will. for f27 i remove the spacers
here is the barlow power of a teleconverter
Any additional questions you can post it in this thread. Anything I can help. ^_^
Fun fact: the same person who donated the 16" on UWI nat sci building, donated a 20" sct to my astronomy group. I plan to do incredible things with that scope.
