Title: Soul Nebula IC1871 from Bromley
Post by: Carole on Feb 16, 2019, 20:22:24
Last time I did this target was back in 2016.
Also called the Whirling Dervish, and if you look close at the main feature you can see why.

Always a challenge to get images from Bromley but at least this one is doable, but it was a first quarter Moon being the image I got on Valentine's night and stayed up most of the night to do it, and had the dome on the Pod Dome table as it was near the Zenith.

Ha 20 x 600
Ha 4 x 900
Oiii 12 x 300 binned x 2
Sii 12 x 300 binned x 2
Also took RGB for the stars, but not managed to superimpose them successfully so have left them out.
Atik460EX, SW130PDS and HEQ5 + coma corrector
Total (without the RGB = 6 hours 20 minutes)

Thank you Roger.  Looking at other images of this, there seems to be a lot more Ha in the lower part of the image (brown) where many other images are blue in this area.  I can only assume the reason for this is the Oiii/Sii signal is weak at this point from a LP location.
