Horsehead and Flame Nebula Hydrogen Alpha from 22/1/2021 and first attempt at combining that data with LRGB image same field from 9/1/2021

On evening 21/1/2021, I collected 100 minutes of data on the Horsehead and Flame Nebulae – first time even using just one narrowband image on an object in an evening – this was on advice of Ken Critchon – and it was excellent advice – as I obtained te image below! Minimal processing – stacked using weighted batch pre-processing script in PixInsight and Photoshop curves to make data visible.

Then I tried to combine this image with my previous LRGB one from 9/1/2021 in Photoshop – a less successful effort! Don’t really know how to do that.
