Tonight I was able to guide with both guide cameras on the same star. The results are interesting. There is much reduced drift in declination but still drift in RA - perhaps 50% of what I was previously measuring. I've attached a screen shot of that test in PHD2.

Guiding on the same star I was able to get a very good result with the SX-AO on camera #2. I used long exposures (7 sec) and low aggression to avoid any over correction. I'm pretty sure I can refine these settings for a better result.

What I don't understand is why there is drift in RA on guide camera #2 when there clearly isn't RA drift showing up in the imaging camera #1 sub of 10 minutes. It's clear from the final position of the AO (star) that it has been compensating for the drift. The image from camera #2 shows no drift in RA. I've attached the two 10 min registered images.

Can anybody reason out this drift?

Thanks,

Peter

The G2-8300 sub is from the TSX guided scope. The Trius-C is on scope #2 and corrected by the AO. Both subs are 10 minutes.
