Prior to a PEC curve, you might want to remesh the gears...then run your curve.

Vega, the brightest one, is now dropping towards the west.  Can it be half

Thank you for the responses to my "Guiding-Good enough" post. Yes. I have run PEMPro, loaded the "model" to the CP4 controller and Enabled PEC on the mount. However, it has been a while (>1 yr) so a new run at it would probably be beneficial. I will make that my first priority. I would like to reduce the RA error.

I have two AP mounts in the observatory , an AP 1100 and an AP 1600. The AP 1100 has encoders. I plan to add encoders to the AP 1600 this summer. I agree that it is easy to get drawn into "perfection" on this topic. However, when you ( all of us) make a big investment in the best equipment ( Astro Physics) you like to get full value. That's my excuse and I am sticking to it.
