Hi everyone,

 

I started a project that I hope I can achieve, I wanted to image M33 - Triangulum galaxy in broadband (so far I have acquired 7hrs) and add about 4-5 hours of the same target but using L-extreme filter to bring out the some of the H-alpha. How do I add the NB images to the broadband images that I have already acquired using Siril software? Do I have to stack both separately (each with their own calibration frames) then add them after when they are both stretched?

Here is my m33 which is done by composing 2 sessions: NoFilter and dualband filter https://www.cloudyni...angulum-galaxy/
For processing I use Pix and in general I follow approach described in this tutorial https://www.youtube....h?v=Us_zl4Qvn1M
