CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
Hope everyone didn't forget Jupiter's opposition date last night. It somewhat cleared magically after the extended monsoonal season, and was lucky to grab some quick data in the still of the night. Here's Jupiter annotated for those new to Jupiter observations. Taken with 8" and Lum camera.
thanks everyone! am grateful for the right mix of sky conditions at the appropriate opposition period rather than the equipment used. Seeing is so very important. Had two previous sessions prior but didn't even bother processing them much. Sometimes even if it appears to be clear, but with numerous low passing cumulus, seeing may not be good (low air flows), and one might get better result with slight haze present. The scope is the same one all these years being used - Tak CN212 which is discontinued. It is slower than an equivalent Mewlon - at F12.4, and imaged with a 3X barlow. LOTS of time was spent achieving focus instead....as focus point can change with time even if one seemed to achieve focus a time period earlier. Throughout this session, I had to do refocusing every 10 minutes. I'll be damned to say that even the C11 and C14 images taken this season of Jupiter somehow did not show as much details as this lucky opposition session with the CN212 which is bearly 8". I think we are in a very attractive location, mirroring the thoughts of Jiahao! Quick observe/take Jupiter these days while u can!
