this rarely imaged planetary nebula is located in taurus and it is
not really bright... (-: I imaged it with 2 different CCDs:
- luminance: SXVF H36; 9" tmb apo f/18 using a 2" 2* powermate (image
scale 0.4 arc"/pix)
2 hours exp time -- 10 min subframes
- color: SXVF M25C; f/9 prime focus -- 10 min subframes.
preprocessing in maxim dl. for luminance I only applied kernel
filter,...no darks (necessary (-; )
postprocessing in PS CS2 and Pix Insight.
Snce the signal was very weak, I picked up quite some noise,...also chrominance noise and therefore I was greatful for the SGBNR feature of PixIS.
seeing and transparency were both very good!
I wanted to make sure to finish this object in one night, as I can
not be sure to have another decent night following immediatly,...and
I was right...
L and OSC data was finally matched in photoshop...tricky but
effective.
Here is the link to the full size image of that object:

thanks for looking!
