Description

Second try at the Little Dumbbell Nebula -- unfortunately a windy night with big stars and some tech pbs. After I finally got it all running (my auto-guider did not start up on 12V for over an hour), dawn prevented longer integration time and the original stack (see 2nd pic) was not at all promising: This planetary nebula was _tiny_, even at f/10 (2350mm), not in center (due to my dual setup, I did not dare to reposition), stars were bloated and grain all over.

It took some tricky processing to come to a version that bears at least some resemblance to (my) expectation (first pic). I am aware this version has been excessively stretched, but I preferred to visualize at least a little of the faint "handles" ;-)
