I've been collecting narrow band data on the Carina Nebula and have only got as far as processing the Ha. Attached is a full frame view with a crop of the Keyhole and surrounds, both in Ha alone. This was 30x 120s subs at unity gain with an ASI1600mm and a 7nm ZWO Ha filter. I'm very pleased I went with that camera. I don't know how the image will look with OIII and SII combined because combining colour channels in PI is definitely not one of my strengths! I'm tempted just to stop now.
A wonderful capture.
A pleasure to see.
I do like the idea of ha for me as it somehow manages the colour to my satisfaction.
I have been thinking maybe do just ha in Sydney as my delight in photos is the detail and ha delivers detail.
Good work.
