LRGB Composition Formula :
L = H-a + OIII unbinned
R = SII binning 2x2
G = H-a unbinned
B = OIII binning 2x2 + OIII binning 1x1
Captured 30/06/2014, 02/07/2014 and 05/07/2014 with Takahashi FSQ106ED @f/5 530 mm focal length with Apogee Alta U8300 monochrome and Astrodon H-alpha, SII and OIII filters 5 nanometers.
H-a - 15 x 20m unbinned = 5h
SII - 6 x 20m binning 2x2 = 2h
OIII - 8 x 20m unbinned = 2h40
OIII - 6 x 20m binning 2x2 = 2h
Total exposure time = 11h40m
Software: MaximDL to capture - CCDStack to calibrate, register, normalize, data reject and combine - Photoshop CS5 and PixInsight for HDR, color combine and non-linear streching.
