Just wanted to point out Eric that it's not going to increase your focal length by very much...from 800 to 1175...still going to be fairly widefield with the DSLR...great for large nebs.

Not so good for small galaxies.

I suppose that why SCT's are good..you can change your focal length by adding reducers.
