Hi Guys
Eta Carina nebula
NGC3372 in colour mapped Narrowband (click 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. 38 hrs total.
71 off 3nm Ha subs 20min each bin1. 28 off OIII 3nm subs 20min each bin2. 19 subs SII 3nm subs each bin 2.
Ive added a few hrs to the Ha previously posted and curved the middle bit for more , less blown detail.
The colour is a bit boosted. Its interesting to see how OII and SII is distributed.
Cheers
Fred
