Comment : It's not often I'm at a dark place. This evening I visited Ingarö but with full Moon it was not that dark as it could be. I tested with 30 photos on the nebula IC 353, it's in center and at ten o'clock of the more famous M45 Pleiades. Much of the colors come from light pollution and clouds drifting by. Better to try another night with no Moon. I at least got some practising of photographing nebulas.
