Some people told me I wouldn't get much from a DOB but I managed to find a way, maybe you are right but I love to experiment and I believe there maybe a way. RGB would most probably be the ultimate. I have another test that I want to try without RGB filters am going to try, I hope it will provide the same effect as photgraphing RGB. I tried to buy some RGB today but nothing in stock state wide at least.

I was using it on the final (8-bit) images.

Haven't seen focus magic will search for it, I have a couple of plugins already 2 of them are CA and the Orion has been dealt with, the initial images were really bad.
All in all I dont have the money to buy a $1000.00 lens otherwise I would buy a widefield triplet carbon fibre scope an do it that way. At least when I get my surgery done I can handle a lense on a camera and can get my wife and/or kids to carry the tripod out an set it up when needed, I already have spots marked on the pavement to place the legs of the tripod. 6 to 9 month later when I finally recover I may use my DOB again.
