Losmandy G11/Gemini mount. The H alpha and OIII subframes were 12 minutes binned 1x1, while the RGB
subframes were 4 minutes binned 2x2, resulting in the following total exposures L:R:G:B = (HA+OIII):
(R+Ha):(G+OIII):(B+OIII) (min) = (288+ 312):(72+288):(72+312):(72+312). Captured with Nebulosity,
calibrated, sigma combined in Iris with other processing using PixInsight LE and Photoshop CS.
