Hi Guys
A bit of an experiment. I curved the Ha as Lum way less than usual, to emphasise structure rather than overwhelming messy extension. Click
Here for big.
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. 40 hrs Total exposure time.
Ha, SII,Ha,OIII. Mapped as LRGB
Ha 40min subs bin1. SII 40min subs bin2, OIII 40min subs bin2.
Bit of trouble with stars, many different colours
