Hi Milton, I think the settings in the post-processing window are the same as when you adjusted them & I copied a month ago or so. I left the reddish colour there as I thought it looked OK but I`m not experienced as to actual registration values for Jupiter. Jupiter was nearly overhead as I just got the barlow showing an image from the camera then adjusted too far & lost it! I wasn`t able to get it into view immediately being too difficult to sight through the finder directly overhead.I gave up at that stage reasonably satisfied at my night`s work. Here`s the image before P/processing.

I was quite pleased with the added resolution with the Baader filter. I later altered the orientation so the "stripes" were horizontal but that attempt is probably too red according to you.

I`ll have another go at it! Thanks, Mark.

Hi Mark;

I re-balanced your jpeg image in Astro IIDC image processing module. Hopefully this will get through and be posted.

To my eyes and LCD monitor settings , your image had way too much red in it. When capturing movies, you likely need to reduce the red slider by about 20% to 30% and increase the Blue slider by about 10% to 20%.

Also was jupiter fairly low (30 degrees or less) above the horizon because it looks like there was some atmospheric dispersion? I offset the red / blue layers to compensate, as the atmosphere acts like a prism and causes the R G B colors to be offset from each other at low altitudes.

Hope That Helps..
