Software PEC for EQMOD mounts #39780
Hi,
I seem to remember about 2 yrs ago there was a discussion about wishing EKOS had a feature to measure and build in a software PEC for autoguiding with EQMOD mounts. I am not aware of this going any further but thought that I would bring it back as a topic or if anyone knows if it's possible to measure PEC in indi EQMOD and use with EKOS internal guiding or even PHD2 guiding in EKOS?
Cheers
Mike

As far as I know it hasn't gone anywhere. But you may be interested in trying the PPEC algorithm in PHD2 as an external guider.
After a worm cycle or two it will begin to apply predictive corrections based off previous cycles. It's essentially single use PEC without the prep, and you can expect guiding to improve the longer it runs.

Software PEC for EQMOD mounts #39863
Hi
Yep I have been using PPEC and it's OK but I am struggling to see that it actually is superior to hysteresis mode. I just wondered if there were any thoughts about developing something similar to PPEC for the internal guider facility that would work well with EQMOD mounts. There is PEC training that that be done manually on these mounts and this info is stored in the handbox I think. As there is a nice EQMOD indi driver it would be good to have PEC training integrated into the INDI EQMOD interface.

Cheers

PPEC is hysteresis with the addition of making predictions.
I agree it would be great if INDI EQMod could work with PECPrep used with the ASCOM version. But I expect it is a great deal of work to implement.
