M27 dumbbell nebula, reprocessed image from earlier in the week. 10x300sec exposures with dark frames. Sky-Watcher 200P 8-inch Newtonian on NEQ6-PRO mount, Opticstar DS-142C camera.

Had another try at processing my pictures of M27 from earlier in the week. managed to get the sky noise down to a nice level while preserving the nebula itself.

Done
