Date: 1 July 2014
Location: High Halden, Kent
Exposure: 12 x 5 min at ISO 800
Telescope: Celestron C11 with TS 0.8x flattener on Skywatcher EQ6 mount.
Camera: H-alpha modified Canon EOS 550D
Guiding: Nikkor 300mm lens with QHY5 camera.
Filters: IDAS LPS-D1 filter
Processing: Stacked in IRIS and asinh range compression applied. Scaled by 1/2
Comments: This is the Red channel only from those 12 subs since the stars in the Green and Blue channels were far more bloated and also didn't line up very well with the Red. If I had known this in advance I would have used an Ha narrowband filter instead to improve the S/N ratio
