Re: 22Nov20 - AR12783 in CAK (Best Image added 23Nov)

Finally found time to do some post processing. This is by far the best High-res CAK image. Taken at 7:50 am local time. It is formed from stacking 25 selected frames. Only minor level and contrast adjustment in Photoshop. https://1.bp.blogspot.com/-oFUOBG6saHI/X7uR4jgDi_I/AAAAAAAAsLg/pV5fR8GBlU4rBoV...

Hi Victor,

I agree with Mark to start with the view using a single etalon. Get that right and then add the second etalon.

Nice image, Alfred, even through the cloud layer. Stu. Hi Stuart, Thanks for your compliment. The seeing wasn't good at all. I could see wavy parts in the movie. In this case, somehow, the thin cloud layer did not result in significant image quality loss. In fact, it seems to have brought about bet...

Dear James,

I am happy to see the supergraulation with minimum processing. This image was achieved with 170 frame stacking, ImPPG processing and level and contrast adjustment in Photoshop.

I understand that these filters are the only 2 ever made. This is how I set it up: The 10-angstrom filter which rejects ever...

Hi James,

It is especially meaningful (getting the supergranulation cells) because I apply very little processing. I am also very glad to see the 3-D effect in the last CAK image.
