Great images - are you making a flat for the full-disc image? Might be your ticket...

Looks great Dan, love the filaprom on the NE limb.  I forget what camera you have, the FOV looks just like the 174

Thanks Mike.  Yeah, the 174 for the full disk, and with a 2.5x barlow for the AR2833.

They look good to me Dan. I have not seen many full disc images that didn't have some gradient, even when a flat was used.

I think your tuning is spot on and the gradient is not that bad.  A flat will help, although I do find them difficult for a full disk.  Have you tried the artificial flat technique in Marty's tutorial?

Beautiful shots Dan.

 

The full disk does have some issues. 

 

I would usually throw garbage can liner, the translucent ones, on the front of the scope with the Sun Shade all the way out.  Take the flat using a longer exposure time.  Try to get even illumination on the flat.  

 

Good shots though Dan
