Excellent Quality

I am very happy with this telescope. The focuser is rock solid. It comes with a primary mirror cooling fan and there is no light leakage in the back end of the reflector. The tube rings and large dovetail plate hold the telescope firmly. The spider veins that hold the secondary mirror are solid and perfectly placed. I have already taken many excellent galaxy photos. Highly recommend this brand of reflector.
