Hi Guys
Its been a while since I posted a pic.
Click here for large.
RCW86 is one of the brightest SNRs observed in X-Rays in our Galaxy
It has been a bit difficult to capture and process, not a common target.
The Palette ended up being an odd Ha.Ha.SII.OIII mapped as LRGB.
Colourising channels in PS certainly makes fiddling with palettes much easier.
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop. 56 hrs Total exposure time.
Ha 30hrs, 40min subs bin1. SII 12hrs 40min subs bin2, OIII 14hrs 40min subs bin2. Short RGB exposures for stars added.
