Ced214 in HST
This was a work in progress as I wanted to add RGB to create some nice coloured stars - Maybe I'll capture that tonight! Anyway, I have spent a long time today processing this with different amounts of data. Initially I tried 6 hours of each Ha, OIII and SII. I thought that if the results were good then it would save me a lot of capture time, although that is still 18 hours.
I found I got a lot of noise with that, so settled on working with all the data I had so far. This has worked out much better and the level of noise was far better with the additional hours. So, for my own little experiment I have decided that I will stick with 1 nights Ha, 2 nights OIII and 3 nights SII.
Details
M: HEQ5
T: Pentax 75SDHF
C: Atik 314L+ with Baader narrowband filters
Ha 19x1200s
OIII 28x1200s
SII 50x1200s
Total time - 32hours 20min
No calibration files and all taken at 0 degrees as I still battle with heat. Whether or not this is worth over 32 hours I'm not sure!! But I've enjoyed it.

Re: Ced214 in HST
Thank you everyone for your comments - I think 32 hours gave it a much more pleasing look than the 18 hours stack. I have wondered long and hard about how much data I needed for NB in particular and was hoping that there were some corners I could cut in regards to imaging time - But clearly not!!
