Hello, I am so totally new here in the world of solar imaging. I have become the new owner of a Lunt 35mm and have been trying to focus for imaging with variuos cameras. The main one is my DMK 21AU618. I have had suggestions that i need to get the camera closer , and further away and I'm really not understanding what to do. I first followed the advice to put the lens part of a x2 barlow into the nose piece of my DMK...bringing it closer. My focus was still way out. Do I need, where would I get a shorter nose piece ..a different barlow, a different focuser than the standard one on the back of the B600? I am sure this is all very basic .....sorry for the level of my knowledge... HELP !!!!! The view is lovely but I really want to image too....... Claire ps links to items I may need or pictures of what to do would be most useful too.
