Description

This is a work in progress, there are only 8 x 1800s subs (4hrs) and the RGB stars that are added to the tone mapped Ha image are 20 x 15s (bin2x2) for each R, G & B filter.

I only started to process this to see how far I could go with minimal subs. All due to learning how to use noise reduction better in PixInsight.

I aim to get OIII and SII data when the weather improves.
