Guiding: On-axis via ONAG-XM and SX UltraStar at 2541mm. FocusLock real-time focus for focusing.

Calibrated and Stacked with CCDStack2. Processed with CS4.

For this version I added Ha to both the red channel, and the luminance. It didn't dramatically brighten the red channel, but it did alter the contrast in some areas. I also created a hybrid luminance. The brighter stars still looked funky, so I copied the brighter stars from the LRGB version, and then layered the original LRGB image at 50% to bring back some of the dimmer stars.

Similar to The Eagle nebula, I like both the LRGB and LHaRGB versions, so I kept both.
