Soul Nebula (IC1848, Narrowband, SHO-Hubble-like palette)

The Soul Nebula, IC1848, is an emission nebula located in the constellation Cassiopeia. IC1848 is the eastern neighbour of IC1805 (the Heart Nebula: flic.kr/p/2p1mT9W), and the two are often referred to as "Heart and Soul". More information on this nebula can be found here: www.constellation-guide.com/soul-nebula/

 

I took this image with my William Optics FLT91 + F68III 1.0x flattener, my ZWO ASI2600MC Pro colour camera, Optolong L-Ultimate 3nm dual-band filter (Ha, Oiii), ZWO AM5 mount with ASIAir Plus for almost 6 hours (in 3, 5 and 10 minutes exposures at -10C and 100 gain). Then stacked with ASIStudio (ASIDeepStack) and processed with PixInsight and Affinity Photo 2.

 

This is the SHO-Hubble palette look-alike version processed in PixInsight. This is an interesting approximate process as the image taken with a colour camera and Ha, Oiii dual-band filter only has HO and not Sulfur, so it’s never going to be as good as an image taken with a monochrome camera and SHO filters.

 

Please see the HOO version here: flic.kr/p/2p136yR

 

I hope you like it.
