Description

M27 Dumbell nebula. A summer classic. One of the biggest planetary nebulas (relatively to us), not whole lot of details for 13cm telescope, but I expected much worse with integration time that I got :) I imaged it during two nights when it was clear after M16 got too low, so it wasn't a long planned image, only imaged for fun as it still was not getting dark enough to continue with other projects :)
