I am having difficulty focusing my ETX 90 when using the higher powered eyepieces so I started to look around on the internet for focusers for the ETX90 that would help me get more granular with the adjustment on the scope.
After exchanging a couple of e-mails with the folks at JMI, they were convinced that their MOTOFOCUS part # MFETX would work for my ETX90 so I ordered one. I received it and attempted to install it but quickly discovered a major issue with the install and to make a long story sort, the current configuration for this device is not compatible with the current MEADE ETX90 MAK Portable Observatory (3514-04-20). It’s designed to fit the older versions. So the MOTOFOCUS is on its way back to JMI, they did indicated that they may in the future build a focuser for the new ETX90 but need one so they can design and fabricate it. In the mean time I am still looking for a solution to my focusing problem. Does anyone have a solution?
