Camera on top!Celestron's piggyback mount is a great accessory for all observers interested in deep-sky astrophotography. The mount allows you to attach your camera with its lens to the top (side too) of your C-series telescope. That makes it possible to shoot with a normal or wide angle lens while guiding through the telescope.This model fits C8 C9.25 C11 and C14 telescopes and mounts to the telescope's rear cell. With it you can utilize the lenses you already have for your camera and you won't need extra telescope accessories to take fine deep-sky pictures or digital images. Don't go to the star party without a NightVision flashlight.
