About this image

Imaged over two nights, 30th Jan21 and 3rd Feb21.

It’s my first serious attempt at this beautiful object. I really want to get a wider field of view of this DSO to truly do it justice – one day I will.


Processing; Deep sky stacker, PixInsight with final tweaks in Photoshop and Topaz DeNoise.
