I have a CEM25EC. Last week I tested the mount and found that it works very well if I guide (despite the very bad seeing on that night), however when I use the encoder, it almost does not do anything. I am wondering if my expectation is high, I am doing something wrong, or I need to re-calibrate the encoder as I have upgraded the firmware, RA, and DEC (manual does not say anything about re-calibration). My setup was WO GT71+ASI1600+Filterwhell+60mm guidescope (I guess the whole setup is well below 10 lbs).
I have attached the PHD2 results for 4 different options:
1- Guiding on and Encoder on
2- Guiding on and Encoder off
3- Guiding off and Encoder on
4- Guiding off and Encoder off
Please note that:
- I was turning off the guiding by skipping output in PHD2
- I was turning on the Encoder by "Filtering RA" on hand controller
Any help is appreciated.
