Looks great John. I've passed over this target a few times. Stellarium doesn't show the amount of Ha present in this target, which is quite abundant looking at your image.

Thanks Brian, a quick search on Astrobin, will show just how much is thought to be: - https://www.astrobin.com/search/?q=Sh2-173

Thanks Richard, I tried so many variants to combine from HSO, HOO HSS, SHO, SHH, you name it and I think I tried it, I knew there was loads of Ha and a good amount of SII with very little OIII, so it was a matter of getting the balance right.

 

I'm also surprised at the number of people who have captured this in LRGB and got a similar colour, this was the RGB for the stars, only 40 mins of each channel, but the Phantom is barely visible: -

Well done John, this little blighter is a bit camera shy, I had a go at it a few months ago and it's going to need a lot of data from where I live.

 

How much data is this by the way?

Thanks Carole.

 

It took me about 12 hours to get that and even longer to process 🤪
