Jupiter 23rd May 2018

Not a scope meant for planets and the image is a bit small.   FLT98 with 4x powermate, Baader L filter, ASI224MC,. Best 25% of 60s video at 200fps. 5mS exposure, gain 405. Stacked in Autostakkert and processed with Astra Image plugin in Photoshop.

Alan, that's a very nice Jupiter for such a small scope, well done.

Thanks for the compliments.  The time was 00:34 so the date should really be the 24th May. With a scope Dawes limit of 1.18" and Jupiter at 44.3" diameter, with my 130 pixel diameter image I'm sampling at 3.5 x the Dawes limit so I seem to have cut through the 'seeing' pretty well even at its current low altitude. The biggest improvement was the L filter. I tried it first without a filter and the red and blue channels were a blurry mess.
