Hi Guys
Processing this produced crazy colours, but on checking Astroanarchys effort, he pretty much got this colour mix too. Thats how it looks in NB
.
Pretty dim, specially SII so:
Nebula NGC2035 in narrowband..(click for big) Mapped as Ha SII Ha OIII (LRGB)
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
40hrs of 3nm Ha bin1,4hrs of OIII bin2 and 9 hrs of SII bin2.
Processed with CCDstack, Star Tools and Photoshop.
SII required 40min subs at bin2!. Ha were 40min subs also and OIII 20min.
Some of the nebulae structure is very interesting.
