Of course Hy, I'll take them as soon as I get another clear night (unfortunately, most likely not in the next 7 days according to the local weather forecast).

I should add more specifics: the situation presented itself during guiding calibration. The central area of the globular was in the guide frame and the auto star selection algorithm tended to pick a bright area within it as guide star. This inevitably resulted in a "guide star lost" error during calibration. So, in practice, the guiding could not really start in that scenario.

I guess I could try calibrating a bit off-target and then moving back to it to see how having the globular in the guide frame affects the actual guiding...

I'll post back as soon as I have the frames.

Best,
Ricardo
