his collimation is OK

Jim shared details of his imaging run. Remarked that after collimating his Newtonian and running the fans for several hours, he found everything iced up. Had to run the hair dryer for 20 minutes. Then clouds rolled in. However, he experienced 10 minutes of clear sky, noting very good seeing. Captured Jupiter. Good detail. Jim appears to be very good at collimating a reflector. I think the image is a bit heavy on the processing though.
