Description

M27 - The Dumbbell Nebula. Images captured from an unmodified Canon 400d (XTi), no filters, through a Skywatcher 6" newtonian.

An experiment to see what detail could be bought out from short subframes exposure times compared to longer subframe exposure times, both iso1600.

(details - 22x120secs with 20 darks, 25 flats. 114x30secs with 30 darks, 25 flats)

I was actually surprised how much detail came out of the 30seconds subs.
