Description

It was overcast all afternoon, and the evening was the same.  I could only see maybe 30 of the brightest stars -- similar to a clear night at my home! -- so I decided to skip imaging.  I happened to wake up at 4am and noticed a sky filled with stars, so I quickly set up my scope and targeted M7.  The stars measured twice as large as the past few nights, but I let it run anyway.  I had to discard a quarter of my subs due to the clouds and the stars were definitely much bigger what I'd want, but the overall image was still pleasing to me.
