NGC 7822

Hubble Palette image consisting of 20 x 10 minutes in Hydrogen Alpha, 20 x 10 minutes OIII & 22 x 10 minutes SII. Total exposure time of 10 hours 20 minutes.

 

I don't think I had ever seen this imaged before until I saw Sara's recent excellent version www.flickr.com/photos/swag72/7796546996/ which inspired me to have a go myself.

 

The Oxygen & Sulphur is quite weak in contrast to the Hydrogen signal, meaning it took a lot of processing between Pixinsight & CS5 to get the colours to the Hubble golds and blues.
