Easter morning Jove

Jupiter captured at 4.12am Easter Sunday morning from Melbourne.

Mirror "chilled" to 0.3 degress below ambient with moments of 7/10 seeing conditions but up and down overall and then deterriorating afterwards. A good shot of GRS junior which seems to me to have grown in size?

Have a safe Easter break everyone.

John.

Nice work, John.

Those tweaks in brightness and contrast definitely made a difference on my laptop screen.

Glad you got something this morning. I was all set up and ready to go...and then so were the clouds

Hi Dave, image defenitely more stable, and more frames to stack. For this image I used 600 frames, so 50% of the frames captured which is very high. So "chilling" defenitely works for me. Overall I think it will mean more frames and more images even in average conditions. Mirror was 0.7 degree below ambient after 5 hrs and had dropped 9 degrees. Only rose 0.4 degrees after cooling was stopped. Just have to now get some consistently good seeing!
