Hi Tim,


I didn't read the long thread on Cloudy Nights - but I love the photos of your scope project. Please post your first light pictures. 


best wishes,

Alan

Here's the capture file for my latest Jupiter upload. Seeing was probably a 8-9/10. Scope was well collimated. But in the images containing a satellite, I could see little pollywog tails pointing north (up) that are probably thermal plumes. Since they were still present after a couple of hours of equillibration time, I suspect that heat from the flea2 was flowing up the primary baffle and into the light path!

Tonight, I'm going to try imaging with my "new" 10" f/6 Newt. I built the entire OTA myself, around a mirror that I ground and figured at the Delmarva mirror making class this past March: http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/3739110/page/0/view/collapsed/sb/5/o/all/fpart/all/vc/1
