Celestron Deluxe Off-Axis Guider (93648 OAG)

One of the best OAGs out there!

Besides being built like a tank (so it's a bit heavy but very solid), the Celestron Deluxe OAG is extremely well thought-out with just about every adjustment you can think of. It comes with wide assortment of adapters (9!) that make integrating it into your image train a breeze. The prism is large and mounted on an adjustable stalk so you can adapt its position to accommodate the size of your camera's sensor. The helical focuser built into the unit makes fine adjustments to the guide camera's focus much easier and is a wonderful feature. If your image train can handle the weight, you can't go wrong with this great OAG.
