Hello, So I have an 8" Dobsonian and a Canon Rebel T1i. I have the t ring and a 1.25" adapter that I attach to my focuser, which is a 2", but I don't have anything that is 2" so I use 1.25. I also have an extension tube that allows me to put a barlow lens inside of it. I have tried both of these configurations, removed my camera lens and attached just the 1.25 adapter, can't get the camera to focus at all. Attached the extension tube and a barlow and 25mm eyepiece on the inside, still no focus. I don't know if I can't get my camera far enough away from the tube, or I can't get it close enough. Any one have any suggestions or tips? Thanks, Michael
