Hi Guys
IC4628 and NGC6559 nebulae in Narrowband.
45hrs total exposure time (40min subs). Not that these are faint, but the extra exposure time allowed more detail to be revealed in processing.
OIII is subdued in this rendition due to it being a bit overwhelming.
Big version
here.
Taken on my RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop. Also Starexterminator and Topaz sharpen AI. 3nm Narrowband filters. Ha, OIII and SII all 40min subs. RGB stars.
Starexterminator has made a huge difference for me in processing, and Topaz sharpen AI,
IF used very carefully and only on dense data has proved to be stunning.
Cheers
Fred
