Temperature compensation is a great feature of the PerfectStar focus controllers (excluding PerfectStarLite), but to perform to its full potential the sensor must read the temperature of the telescope accurately and not be influenced by the surrounding air, since they will change at very different rates.  That is, the sensor must be thermally coupled to the telescope tube and insulated from the air. This can be done with the standard sensor, but requires some planning and effort on the part of the user.  PerfectTemp makes it much easier:  Just place the sensor block face down on the telescope tube, secure […]
