Messier 3 Globular Cluster

[stevewanstall]

I didn't have long tonight so I decided a globular cluster would be a good target. In the end I ended up imaging seven. The only one with enough data to do anything with was M3. I also made use of the tutorial on here to  continue to learn how to process LRGB images.

 

The image was taken at:
Gain 139
Offset 21
Exposures:
Luminance 114s x 65 binned 1 x1
Red 114s x 10 binned 2x2, Green 114s x 7 binned 2x2 and Blue  114s x 5 binned 2x2
Calibration frames: Darks, Flats and Dark Flats.
PHD2 Dithering
Equipment: Celestron 9.25 XLT at F10,  Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope, Celestron Focus Motor
Software: Ascom 6, Eqmod, Cartes du Ciel, AstroPhotography Tool, PHD2,
Processing: DSS to align and stack the subs, PS CS5 to combine and stretch RGB and stretch Luminance and then to create LRGB. Lightroom 6 to develop image further.
