Description

here was an interesting webinar on Telescope.Live the other day, about using Sii (or a combo of Sii and Ha) as Luminance in SHO images.

The demo object was M8, from 7 hours integration from their 24" scope in Chile.

The demo used astro pixel processor, pixinsight (mainly just to run StarXterminator and BlurXterminator), and Affinity.

Here is my version, using Autointegrate in pixinsight, and photoshop

In the demo, the presenter used a paint brush to combine Ha and Sii luminance, which I didn't 100% follow what his criteria for painting in Ha was. In my version I used an opacity slider, on the Ha layer, and mixed by eye with Ha ending up at 51%.
