Thanks Peter, given that SB could not provide me with a fix by date for the Southern Hemisphere PE “doubling up” issue, I used PEMPro last night and had excellent results.
It only seems to work with the 32 Bit version of The Sky X, so I had to configure that to get the ball rolling. I also got an ASCOM error for my camera (QHY268M Bin 1x1) but when I changed the Binning to 2x2 it seemed okay.
For the pre-PEC run, PEMPro reported the following for my MX+ Mount:
RMS Error = 0.834
Periodic Error = +2.1 / -2.1
For the PE Enabled validation run, PEMPro reported as follows:
RMS Error = 0.752
Periodic Error = +0.0 / -0.0
I was a little puzzled by the 0 value for PE so I slewed to M8 and then M16 and grabbed 120 second test shots (at a FL of 2250 mm) and the stars were nice and round, no sign of any egg shaped trailing, etc.
Previously, in a batch of 30 sec exposures I would have some 10-20% showing evidence of slight trailing, so a good result.
Thanks again for commenting in my problem report post on the SB Forums, it steered me in the right direction.
Ypipee - no more autoguiding....
Cheers
Dennis
EDIT:
1. Just added a 60 sec x 20 frames Unguided Raw shot of M16. No calibration, just Align and Stack in PI so it looks a little rough.
2. SB just advised that PEMPro can be used with The Sky X Pro 64 Bit and their ASCOM2X Mount Adapter, so I will give that a try next time.
