Not sure if it belongs here, but would like a resolution to this. I keep losing the guide star at seemingly random times. It happened only once last night, but has happened several times before. I’m using a Mach 1 w/ a TMB130 and an OAG w/ an Ultrastar. The SNR of the star last night was very high. I am pretty sure that it’s not environmental as there were very calm winds last night and I have a well managed cable system. I’m using APCC and PHD2 w/ SGP, and haven’t had a hiccup like this before aside from the two most recent nights. The only piece of software I’ve changed was SGP from the previous release 22.214.171.124 to 126.96.36.199. The event occurs from 12:08-12:15am.
After losing the guide star, SGP and APCC locked up and I noticed the telescope box had ‘Unknown’ for the RA and Dec. There apparently wasn’t communication between the two programs. I had to reboot to clear the issue and after starting up PHD, SGP, and APCC I could get them all talking to each other again and resumed the night. To be safe, the rest of the night, I turned of dithering and it ran w/o an issue. However, I’m not certain that fixed it, and want to be able to use dithering in my sequences.
Notes from the logs:
- APCC has a gap in time from 12:08:20 - 12:12:20 and then again until 12:14:20 and 12:15:09. Very strange.
- At 12:12:29, SGP reports a failure of integrating one of my light frames. This has also happened in previous logs.
Here are the logs of SGP, PHD2 and APCC:
I would appreciate any help or advice you might have for me. Thanks!
