Focus on Jupiter

I tried taking a picture of Jupiter with my Nikon D5000 at Prime focus on my celestron C6-RGT. But the picture was to small to show any detail, So I dropped in a 2x Bar;ow and then couldn't get it in focus, Ive got a Crayford focuser and it seems the tube is to short for me to draw it out far enough !

Steve, you'll need to get an extension tube, either 1.25 or 2 inch depending on your format for the DSLR adapter. The extensions are available from a number of sources, like Televue, GSO, Meade Celestron etc.
I see you live in Crestview, I spent 1977 through 1982 on Pensacola Beach and in the city. I wonder if the beach area still has those amazing dark skies in the winter?
