Finally got a reasonably good night and after updating PHD2 and finding a good star in NE soon noticed that DEC was drifting which increased over exposure time.? I am using a STi as a guider.

My question is whether others have fount this issue and how did they solve it?? I did several weeks check the balance of the unit and it was spot on east or west with all gear on mount/scope/camera & all cords etc.

Please note that I am not sure I have the corrects settings in PHD2 to increase the response to the DEC so any suggestions about PHD2 would also be appreciated.? My scope by the way is a Tak E180 and the guide scope is a Televue scope usable for terrestrial or stars.

Thanks in advance for any help/suggestions to check.

Hi,
I have only had 2 nights since Mar with no cloud.? I lost both of them to something that sounds similar.? PHD2 could not calibrate DEC, and when I started guiding, it showed a classic control overcorrection, with the variance in both dec and RA increasing with each correction.? Not sure if I have the logs, and perhaps if I do have them they may not be so useful, as it made no sense to just let the guiding run.

While searching/finding the relevant PHD fault finding guide for some inspiration, I bumped into a post that indicated that a re-install of PHD2 back to the earlier version had worked for that OP.? Sorry, I cannot recall whether the last time I tried imaging whether the latest PHD2 update had applied.? I did a quick re-test and it seemed PHD was working again.

I am very new to the "game" so it is also more than likely the error was the human operator.? Though for the failed evenings, I did pull down and reset up from scratch both nights.

Maybe/maybe not helpful?

Cheers, Phil
