Jupiter 3rd August 2009 – Mewlon180, x4 PowerMate, DMK31

Hello,

After 4 consecutive unsuccessful nights trying to image Jupiter, I was blessed with a short spell of quite good seeing, maybe 7/10, between 00:30am and 1:00am, early this (Monday) morning.

Mewlon 180 F12, Televue x4 PowerMate, DMK31AF04 CCD camera. This gave an effective focal ratio of F48 with an effective focal length of 8640mm although I really struggled with photon throughput with an aperture of “only” 180mm. I didn’t quite get away with using the x4 PowerMate, and with hindsight, should have plugged in the x3 Barlow; but boy, was it nice seeing Jupiter so large on the screen!

Thanks for looking!

Dennis
