Thanks for the information Paul. I'm wondering how much better/easier your process might be, with 12 bit data. It seems that whenever I work on JPG's (or other 8 bit images) in Photoshop, I get only a couple operations before the histogram starts falling apart.
I've never looked through a solar scope, so I can't really comment on Peter's review. But IMO, a little limb darkening gives the image an appearance of a ball instead of a disk.
