Thanks Peter - though as I know myself keeping log is for me a harder task than all capturing and processing
but makes sense and I'll try
Robert - I used 2 ways of combining Ha to RGB - one was described by Astrobackyard's Trevor where you take red channel from RGB and combine it with Ha and then you use that as a new red channel in rgb - I used it in my Orion nebula photo but that one is too messy at the moment to actually benefit from it. Plus it is dead easy to do in Photoshop but in Affinity Photo you have to go through loops an hoops so there is that too.
On this one I took a bit lazier approach - I put Ha starless stack as a new layer above the starless layer and used hue or colorize to blend and enhance red and the structure in the nebulosity. There is some improvement and as for if it is worthy with RGB - well jury is out on that but to me it is worthy on Ha rich targets - and if nothing else it is a good exercise for me.
