How do you do it?
I’m now guiding with an OAG on my SCT (1422mm FL) which has improved my stars immensely. Last night I had a sequence running that followed the first target until near my western limit. It then slewed back to start the second one which was east of meridian. Plate solving worked fine but no stars were visible to the guide camera so the sequence failed.
This is obviously not a bug with SGP. I’m looking for help with technique. How can I automate a sequence and be assured of a star being in the guide window? When the first target started, the second target was below the horizon so I couldn’t actually check to see that there were guide stars.
Is this just the limitation of using an OAG and I need to stick to one target, even if it finishes at 1 am? Right now I just let it go and hope that it finds a guide star for the second target. Usually it doesn’t and stops.
I am considering a new guide camera. Right now I’m using an ASI120MC at 640x480 resolution. Maybe a mono camera would be more likely to find stars. Something like a QHY5L-II, Lodestar X2, or SBIG ST-i? What do you think?
Hey, maybe that could be a feature request. Could SGP nudge the scope a bit if PHD2 can’t locate a guide star?
