Excellent Temperature accuracy and control

I purchased the thermistor to assist with focus control during long imaging sessions. When used in conjunction with the ASI Air Pro it will re-focus after a 3 degree (C) change and assists with expansion or contraction of the OTA. I have used it this winter and found it helpful since the temperature does change significantly during the nights here in the northwest US.

Excellent focuser

So far great experience. I've had about a dozen sessions and it works great. Only problem I've had is the EAF doesn't provide a mounting solution for the Sky Watcher Esprit100ED. I had to fabricate a bracket, but no big deal and the focuser has been performing as expected. Unfortunately auto-focusing is not supported in the ASIAIR Pro, so it pretty much is still a remote but manual focuser.
