wargrafix, I hope you won't mind these very basic questions from a noob, but I have been drawn more and more to images of solar activity, and when I saw your post I was encouraged by your equipment list to think about giving it a try.  The resolution of the light bridges in AR2786 is fantastic. My principal equipment is a Nexstar 8SE, and a ZWO 224MC, and my question is about your use of a 3X teleconverter: what did you use and how did you fit it? TIA!

BTW, my wife taught at UWI on a Fulbright in 1994, and for 6 months we lived in St Augustine right off the Eastern Main Road.  I'll never forget Carnival, those beaches! and everything else about that great time!

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.
