Carina in Sii - now in color

I've swapped my Ha filter over to Sii and started collecting data on a few targets in view to start doing bi-color for a start.

This is 6h with a Baader Sii 8nm shot over 3 nights in July. 4th, 27th and 28th last night. It is a lot harder than shooting Ha.

Not sure if that's because there is less of it or if the camera is less sensitive to it but it's a real drag to get the noise levels to an acceptable level.

Full fields are below:

I have a HD version here [1920x1393 - 1.84MB]
and a 1:1 version here [3233x2345 - 4.06MB]

Will try to work out a bi-color blend with some Ha that I already have if I manage to do an interesting palette.

PS: added a funky blend with available channels to date.
Ha (red) IR (green) Sii (blue) .
The stars are a sum of all channels. You won't see the Ha stars because they are taken over by the multitude of stars present in the Sii channel. The fat stars are the most prominent stars in the Infra Red channel.

I have a HD version here [1920x1513 - 3.18MB]
