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

Already, in the gathering dusk, a few of the stars are turning on their lights.

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

a year since I watched her April rising in the east?  Low in the southwest

Antares blinks a sad farwell to fall...

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.
