Logs for SGP and PHD to be found here https://www.dropbox.com/s/ubz1hvdp89lbvro/Logs.zip?dl=0
For the past couple of nights I’ve been fighting with a very bizzare issue that I can’t seem to solve and as nobody has been able to help me on Cloudy Nights, I am posting it here as an SGP issue.
I’ve had several clear nights this week. The first night of imaging, everything was working fine until the middle of the night when PHD guiding went nuts for no seemingly obvious reason. Although I was able to restart the guiding relatively quickly, SGP wouldn’t move the mount to centre after plate solving and I lost the rest of the night. Someone on Cloudy Nights suggested the guider had switched to a hot pixel, reasonable assumption. However, the issue has repeated at almost the same time of night for a further two imaging sessions. My logs contain details on SGP and PHD for the last two nights. Everything works fine early evening and there are no issues with PHD or plate solving. In an attempt to trouble shoot last night, I got up and tried a number of things. Firstly, the mount is polar aligned, clutches are tight, balance is good. I’m using an Avalon Linear mount and have never had an issue with it. I discovered that plate solving was solving the image but wasn’t centring accurately by a few hundred pixels. This is what I believe is causing the sequence to abort or get stuck on a plate solving loop. I installed Astap to see if it was the plate solve program but no difference seen. I then slewed to M81 and tried to plate solve - same issue presented. I tried Vega - same issue presented. I tried Arcturus in the south and it solved and centred to within a couple of pixels. I’m completely perplexed by the issue. Worth noting that I installed windows 10 on my Eagle as SGP had stopped supporting Enterprise and I was unable to update - could there be some code somewhere that needs resetting (sorry, I’m not very technically minded). Please would you be able to look into this issue as it’s clear again tonight and I’m expecting the same issue.

Hope everyone is ok over there - lock down here in the UK is strange but is giving us imagers more time to do what we love!
