for $109 you can't go wrong with such a fine built focuser. it certainly worth every cent for me. It might not be a moonlight, but the price is a bargain for it. grab one
in regards to focusing issue, i can't comment on that as i had difficulties with mine using my DSLR. not enough in-focus. I made my own prime focus adapter. just use an ordinary 2" barrel and attach it to the t-mount.
