It's not real stable though. It clamps to the eye piece but uses hard plastic to hold on to the metal tube. Wants to slide off and the weight of my cell phone almost flips it right off, hangs way to far off the rear and has the telescope on the point of flipping over. I'm going to try mounting the phone 180 deg reversed and flipping the picture in the photo editing soft.
As the Marines say "Adapt and overcome".
