Hi Jim;

Thanks for the log.

Were you using an IR filter or not? I'm sort of thinking no because the high blue gains. That tends to saturate the camera in the red range.

And was CCD over drive on or not? It's not recorded in the Camera Settings as I forgot to add it in (that is now in my to do list). It also tends to require more blue to balance out the image too.

I played with it a bit and other than the limbs of the rings being a bit too bright, the color is their in the image for the disk. I'll send you the image and Astro IIDC image settings I used to get their directly.

Hi,

Thanks to Alan & Milton for suggestions regarding getting decent color data for my LRGB

Saturn.  I removed the 2x barlow so focal length is about 2500 mm which allowed me to

reduced the brightness setting.  Still rather unsatisfactory results compared to my

monochrome Saturn images on the Flea.   Here are the camera settings:

I've stretched the histogram in PS to increase brightness and cropped it to give a small tiff

file for anyone interested in manipulating it.  Thanks!
