Hi first ever tri color narrow band image.
Eta
40x5min Ha
18x5min S
18x5min O
hubble pallet
8" f4 newt, Skywatcher coma corrector, QHY9/filter wheel, baader filters.
A rough bit f processing using only Astroart - not sure how it will look as my monitor needs calibration, and I've never done color narrow band before. Prolly need more sophisticated processing skills than I have.
cheers

Even on your 200K thumbnail, we can see it's rich in detail and well captured. Looking at the histograms, you can set the zero points for R, G, and B quite a bit higher, giving higher contrast without loss of information. If you do that, and then up the red channel a bit, it is excellent. It can even survive some gentle wavelet sharpening.
I was a little reticent to push colour too much - my monitor currently has a color cast that makes it difficult to know how to balance the colours - this will not be a problem in a few days as I am getting a loan of a calibration device.
I have limited software as I only have Astroart which was fine for me when I was doing one shot color, but is not adequate for narrow band. I currently don't have the spare cash for everyone's favourite Pixinsight, so I'll have to just try a few alternative approaches to getting the most out of the data.
After 2 years of equipment issues I'm just glad I now have data to play with !!!
although it lacks colour in general.
