I am having some issues using my 2x Barlow in my planetary imaging setup. I have an 8" F6.3 SCT, in which i use an ASI120 MM to image planets. If i do it natively (no barlow) then i can get great pictures that react nicely when i sharpen them in Rexistax. But when i introduce my 2X barlow into the setup, i am unable to sharpen the final image to pull out additional detail. Instead, it just gets more and more grainy. This IS a lower end barlow (Orion shorty) so that is one thing i am suspecting might be the problem. F/13 isnt THAT much magnification, so I doubt that the culprit is just bad seeing. Do you guys think its just that my barlow is too low of a quality and is degrading my final image this much?
Thanks for taking the time to help me out!
