Unmodded Canon 450D

Skywatcher ED80 on HEQ5

DSS and PI.

Was the summer long? Yes it was! But here I am again, taking advantage of the few dark (-ish) hours we have at night. The Astronomical Twilight hasn’t reached my latitude yet (it will on August 23rd), but at the zenith it looks like it’s dark enough for some imaging.

The image you see above is a crop to 100%, so please click through for the full sized version. It depicts NGC6871, a young and bright star cluster in Cygnus. The cluster should be bathing in a see of red hydrogen-alpha clouds, but my unmodded Canon 450D is pretty much blind to that. And what you see is the stack of mere 33 minutes! It’s the only time I had before the clouds rolled in, but the result is not too shallow.
