Description

I have included the individual narrow band images as they might be of use to those wishing to image this target. SII (3nm) = 22 x 10 minutes, Ha = (5nm) 23 x 10 minutes and OIII (3nm) = 22 x 10 minutes. Taken at f/4.4 and 264mm focal length with a Sony 814 mono CCD sensor, pixel size 3.69 microns.

I also acquired in each red, green and blue 12 x 3 minute exposures.

The total integration time was 778 minutes.
