Weird guiding issue
Last night was imaing the Tarantula Nebula (tends to stay more or less in the same spot in the sky) and my guiding was good and bad throughout the night.
My guiding was bang on for a bit, then it went off in the DEC or RA then recovered. Every now and then it said it couldn't make sufficient adjustments so I am thinking maybe the object wasn't high enough?
I do have the log which I can provide but it is quite big.
Any ideas why guiding can be up and down?
