M27: ten hours total exposure

I shot this image of M27 over the past few nights through Ha, [OIII] and a
Blue filter.

I had 5.75 hours of Ha, 3.25 hours of [OIII] and one hour of Blue.

The emission line exposures were 15 minutes and were exposed through Custom
Scientific 3nm FWHM emission line filters.

The camera is a Finger Lakes IMG1024S "Dream Machine" which uses a Tektronix
TK1024 sensor.

An SBIG AO7 was used along with an SBIG ST7E and an RCOS Optical Systems
Dichroic Beam Splitter to guide and AO-correct the FLI camera.

The imaging scope is a Celestron C14 operating at f./11 (3910mm Focal
Length) mounted on an Astro-Physics AP1200GTO mount.
