Hey, so I got a Celestron 8SE that I've used for years. I bought a skyportal WIFI module for it, I'm using a 12v power supply and when I turn it on, the hand control is fully responsive and the scope slews properly. The issue comes when I seat my module into the AUX port. It clicks and when I turn on the scope I get "No response 17, invalid model". Sometimes it's No response 16, no lights, no WIFI signal But when I turn it on without the module it works fine Edit: Spelling submitted by /u/Asaltyhabsfan [link] [comments]
