M27 - The Dumbbell Nebula

22:02 29/7/2006 UTC

Here's another planetary from relatively bright late summer sky. This time the transparency wasn't that good, part of the time there was smell of smoke from forest fires, I think. Anyway it was nice and warm outside, took about 100 exposures of which like 98 should have been discarded due to tracking errors... I decided to stack 40 of them anyway resulting a bit odd shaped stars, but quite good signal on nebula, considering the conditions.
