Trying to get proper processing of Ha, S11 and O11 data for M20, This is 15x10min of Ha data which I feel shows the excellence of the Kodak 8300 chip. Scope was a 10"SCT with f6.3 reducer.
Wow – there is some serious detail in the nebula – top shot! The background looks almost too black – is this a feature of H alpha, or maybe it’s just my (un-calibrated) monitor?
Thanks for all the nice comments.
Im waiting to hear from Martin Pugh about how he did his NB shot of M20 and which channels he assigned to each filter. His shot is to die for and I have about the same amount of data for the S11 and O111 but my processing sucks bigtime and I need someone competant to lend me a hand.
When Im happy with the result Ill post the final image.
