Hello all, Last night my calibration failed. I am using the Sti on a Orion ED80T-CF piggyback onto a VRC10 from Mallicam mounted on G11 driven by the new Gemini 2. The first time I had the problem of failed calibration was during last winter at -25C. After looking at all my connection, switching all wires and even tried another Sti, I finally found the problem being a bad lubrification of my mount. I cleaned and use silicone grease (permatex) on the wormgears and finally got the famous X when doing the calibration. That solution lasted 5 months only. Unfortunetly last night my problem came back but worst this time. The results were as follow: Star Positions Initially:Star at pixel 213.11, 217.91 with brightness 7956 +X Relay :Star at pixel 212.56, 217.60 with brightness 7580 -X Relay :Star at pixel 211.70, 218.01 with brightness 9013 +Y Relay :Star at pixel 211.88, 217.92 with brightness 9714 -Y Relay :Star at pixel 212.39, 218.86 with brightness 4738 Calibration Results +X Relay : Speed = 0.00 at 0 degrees -X Relay : Speed = 0.00 at 0 degrees +Y Relay : Speed = 0.00 at 0 degrees -Y Relay : Speed = 0.00 at 0 degrees All relays de-activate themself. We tried pointing differents parts of the sky. I even tried to guide with my ST8300M with another computer and differents cables and the results were the same. I really thing that I might have a problem with the mount or Gemini since all hardwares were changed except for the mount and the Gemini. I think sending back the mount and Gemini for check up by Losmandy. But before I would like to see if anyone have seen this problem before. Why are the relays deactivating themself?
