IC1318 - modified SHO with RGB stars (WIP)

[MartinFransson]

Wow, this was harder than I thought!

I´ve spent half a day trying to work out the best way to process and combine my data. There were issues, mainly due to two things:
* Lack of data
* Reflexes from filters
* Focus slightly off on the green and SII making weird star shapes.

The lack of data is hard to work around but the reflexes I´ve tried to eliminate in post processing.

The data used is:
18*180s Ha
22*300s OIII
21*300s SII

For the stars I only had a test run of 10*30s L and 6*15s each of R, G and B. Not nearly enough of course. To bring out some of the faint red stars I actually had to blend in some of the Ha data in the star layer.

So. This is a somewhat artistic interpretation of my data ?  Not where I want to get it when it´s finished but considering the low amount of data, I´m really happy with it!! ?

ZWO ASI1600MM-Cool
Sigma 500/4,5 EX lens
Astrodon 3nm Ha filter
Baader 8,5nm OIII filter
Zwo 7nm SII filter (probably mounted the wrong way)

Looks good-its hard to overcome focus issues.  By the way--how do you mount a filter wrong?  It doesn't matter which side faces in/out.
