Hey all,
I know Warren asked for no more Veil Nebula images, but I thought I'd sneak one in after the breather we had
Here is my pass of the Veil Nebula complex shot in July this year. I used the what-is-becoming-popular Ha/OIII mapping to emulate an RGB shot. For good measure, I also shot 70 minutes each of RGB to provide a more natural color for the stars. I was just barely able to squeeze the main components into the FOV of my FSQ/6303 combo.
Imaging specifics:
Camera: SBIG STL-6303 Class 1 with CFW-L 8-position filter wheel and Astrodon Narrowband (H-alpha, SII and OIII) and LRGB filters
Telescope: Takahashi FSQ-106N
Mount: Astro-Phyics AP1200GTO
Guider: SBIG Remote Guide Head
Guide Scope: Borg 45ED
Exposure Information:
Ha: 15 x 30 minutes binned 1 x 1
OIII: 13 x 30 minutes binned 1 x 1
R: 7 x 10 minutes binned 1 x 1
G: 7 x 10 minutes binned 1 x 1
B: 7 x 10 minutes binned 1 x 1
Total Exposure time: 17.5 hours
H-alpha information was mapped to Red, OIII to Green, and an Ha/OIII blend (about 15-20% opacity for the H-alpha to emulate H-beta) to Blue. I actually collected more information than was used, but had to discard some bad shots.
CCDAutopilot was used to automate the data gathering, controlling MaximDL, TheSky6 and FocusMax. Preprocessing was done in MaximDL, and post-processing in Photoshop CS.
