Jupiter during transit of the GRS 12th December 2012, fair to good seeing, sub zero temperatures.
I have attempted to image Jupiter many times before but the results were always disappointing to say the least.
This time I spent a couple of nights star testing the scope to achieve the best possible collimation, I also allowed myself plenty of time to cool down the scope and used one of the moons to get the focus as sharp as possible.
Also a bit of luck with the seeing has given me my best image to date.
