My first M57 luminance, with ASI178MM and APM 80mm F/6

[michael.h.f.wilkinson]

Just managed to grab 800s worth of data in luminance, as an experiment with the ASI178MM at only 480 mm focal length. Stacked in APP.

I am still stacking H-alpha and O-III data (very little, hazy cloud was building up). Will combine these later. I rather like the central star and hints of the spiral galaxy near the Ring. I hope to add more data later.
