What Constitutes Good Guiding?

Recommended Posts

Pecprep is part of EQMOD but you download it separately. A simpler way to get a pec file is to use Autopec in EQMOD. You can just guide normally and activate recording in autopec, no need to switch off guiding output. Once you have recorded a set number of worm cycles you can start using pec. Autopec also generates a file that can be filtered by PecPrep.

I found this method a bit easier, but it's been suggested that the already suggested method using PHD2 is more accurate. I wouldn't feel qualified to comment on that.

I do also believe using PHD2 log and PecPrep to be more accurate.

There are couple of video tutorials on PecPrep - worth looking at (they are short and easy to understand):

If you follow next videos - you will get each part in a row.

I think a worm cycle for the HEQ5/EQ6 with 144 teeth on the worm wheel is 10 minutes , so I'd hope 30 - 40 minutes would be sufficient?

I believe worm period on HEQ5 is 638s (135 teeth so 10 minutes and 38s) while on EQ6 is smaller (180 teeth, larger worm ) - 479 seconds, or a second under 8 minutes.

Recommended "dose" of PEC is at least 5-6 worm periods, so indeed 40 minutes is minimum for EQ6, but I would not go less than that - it is like regular stacking, more data, greater SNR and more precision in PEC curve.
