60. M27 (stack of 2 sets of data from 2 nights)

Both sets of data were taken with Vixen AX103S astrograph + LPS + 40Da @824mm F8
13x180s @iso1600 from PTC in 2013
28x180s @iso1600 from YL in 2013
Stacked in DSS and processed in PS

That should be one of my best M27 images taken with a 4" scope in Hong Kong.
