Description

First Globular Cluster captured with my ASI294MC Pro and processed in PixInsight .

I had captured 41 subs, but rejected anything with eccentricity above 0.65 and FWHM higher than 6. With other targets I allow a little higher levels than this, knowing that I'm going to shrink the stars down anyway. But in this case it's all about the stars....

I wasn't sure how many subs/how much time to image to get a good result - 1 hour 21 minutes turned out OK
