Hello Alan,
This is one of the most detailed, if not THE most detailed image of jupiter I've seen that has been taken in the N hemisphere this apparition. You're not the most prolific imager in the top drawer of planetary imagers, but your stuff always has a wow factor and , I'm glad to say, done on a Mac so I've no excuse for one. Actually I got a fairly decent Red of Jupiter a few weeks back with the GRS I must post it for the group to see. I've invested in an observatory dome and it means I'm far more inclined to go out at a moments notice and could catch the elusive good seeing, also it will enable me to get more practice and experience which should improve my results.
How many frames were involved in the entire capture BTW

Hi Terry,
I use a 10" mak/cassegrain at f30, DMK camera controlled by Astro IIDC and Photoshop. This is a quickly processed stack of about 200 frames through a red filter - image size is reduced. Color images and more detail to follow.
thanks,
Alan

Alan, very nice indeed.
Can you tell us about your setup and any processing that might have been applied? Are we looking at just the red channel of data? How many images, etc..

Hi all,
I had an opportunity to image Jupiter last night - first since 2007 as Jupiter has finally moved above the power lines that line my backyard. The GRS was just past transit when I was able to pick up the impact scar rotating into view. This quick recording through the red filter shows the separation between the two:

It was a nice night of activity, with an eclipse and occultation of Europa by Io. Hope to have some time over the weekend to put together some finished images.
best wishes,
Alan
