Yesterday I shot the 'Running Chicken nebula' IC2944 with my Canon 6d and Televue Genesis prime focus.
First I took 12 frames in Halpha ISO 6400 of 3 minutes. These stacked in DSS and in Photoshop done the following with 'autosave.tif':
- Image => Black & White and then only red enhanced and all colors except magenta disabled. Result a B&W image of the red color.
- Channel mixer => green and blue disabled so only the red channel is visible and the image turns red.
- Levels => stretched a little bit.


Photo 1: 12x3min 6400 ISO Halpha
Photo 2: 12x2min 1600 ISO no filters
Photo 3: the composite (not completely aligned, hence the lighter left edge)

May I politely suggest these instructions: http://starizona.com/acb/ccd/software/ps_hargb.aspx

To add Halpha is always thorny. The starizona instruction is interesting, think it should work. I prefer PixInsight with the NRGB combination script.
