Slewing to targets with different gear ratios #59601
Hello,

My attempts to get my Vixen SP to be INDI/EKOS/KSTARS ready have hit a snag. After multiple attempts, I think I have come to the end of the journey. The gears are not helping INDI.

My RA is 36:12 = 3:1. My DEC is 30:10 = 3.1. However, 3:1 <> 3.1 in this scenario. The RA belt is 5mm and HTD. The DEC is 3mm and HTD. DEC is 67% faster that RA. As such, INDI thinks it’s someplace but it’s not. Targets KSTARS says I am at are empty space in the reticle. The moon is way above where the OTA is pointing.

Here is the strange part. Home is home is Polaris. It has no problem getting back. Going any place other than home is a lost cause. Everything slew is appreciably below target and to the left. Andromeda should be a lateral move east from Polaris. I am pointing to the horizon.

I am at this juncture by choice. The 36:12 is much bigger than the 30:10 physically. 3:1 is equal to 3.1 mathematically. Plenty examples of different RA and DEC on vendor mounts. What should be done in EQMOD when DEC and RA arrive in two different speeds?
