PEC Training HEQ5

[grantboxer]

I would like to do PEC training on my HEQ5 and wondered if you can use an auto-guider to feed the corrections to the mount. Perhaps someone can advise what the necessary steps are for PEC training.
Thanks Grant

Ummm... not sure that you need to use it. Not if you're shooting with the comfortable focal length of the ED80. I 'think' that PEC may interfer with auto-guiders... still learning myself.

More importantly - how's your polar alignment?

P.S. the experts will chime in soon :)

Perhaps tell us a bit more about what you're up to Grant? This would be programmed into the handset presumeably? Are you having imaging troubles?

After playing around with it over 18months I think it is worthwhile as it minimises movement in RA axis, but with caveats:

- EQMOD pulse guiding (isn't confused by the PEC versus guiding commands)
- you already have great tracking and no flexure issues
- you lose it whenever the mount is not parked/unparked successfully and religiously (only takes one crash and you've lost all the hard work).

Even then, as Logie says you may be struggling to see much at the image scale of the ED80. PECrecorder works well with a webcam. I currently use a SSAG with Maxim and send the tracking log to EQMOD's Pecprep program.

Not sure about getting it back into the handset though - I've never been there....
