"I purchased this as a replacement to the standard focuser on my RC. This was one of the suggestions by TS. The very detailed product descriptions for each product gave me confidence that it would meet my needs and was within my budget. When I received the focuser it was very well packed and exactly as described. Its well made and proven to handle my imaging setup easily."

"excellent quality and workmanship. A big upgrade from the stock GSO focuser. The rack and pinion means no more slipping when focusing. Fits the GSO RC10T perfectly and handles the weight of the TSRCFLAT3+EAF+EFW-7+ASI6200 camera."

"Fit and finish was good. Took very little effort to fit a RoboFocus motor to it, and mount the unit on scope. Operation has eliminated slippage with heavy filter wheel and camera. (SX35 and maxi filter wheel on GSO RC12.) "

"Sehr guter Auszug, sehr stabil, hällt die Moravian G2 8300FW problemlos. Auch die Rotation geht hervorragend."
