Having lots of fun with the eyepiece projection adapter. GSO 10" F4 on a HEQ5 Pro, Pentax K-5, 2250 frames stacked in registax and finished off in photoshop. I think I'm getting the hang of registax's weird wavelets.
I think the top sliders do fine unsharp mask and the bottom ones do coarse. Then there's sharpening and noise reduction boxes.
I notice I'm getting the dreaded onion rings on the outer edges. I'm also getting bad CA or colour there. I think the onion rings are a result of getting rid of the edge colour. It's hard to win on all fronts!
