Scope: Planewave CDK 12.5 f/8, 2541mm
Camera: SBIG STL-11000 with Astrodon Tru-Balance E-Series Gen2 filters
Temp: -15C
Mount: Losmandy Titan
Guiding: On-axis via ONAG-XM and SX UltraStar at 2541mm. FocusLock real-time focus for focusing.
Exposure: LHaRGB 230:405:105:110:105 Ha subs are 15 min, all others 5 min. Luminance and Ha unbinned, RGB binned 2x2.
Calibrated and Stacked with CCDStack2; RGB combine and DDP with MaximDL. Processed with CS4.
I wasn't happy with my previous image of this, as the scope was out of collimation and my processing wasn't the best.
There are 3 versions of this image: one LRGB, and two LHaRGB images.
This was my initial attempt at adding the Ha. For this version I added Ha to both red and luminance, at 30%, and left the stars alone. I still think there are too many stars.
