Description

With the new RASA equipped, a challenge with my first mosaic of Orion and the Horsehead nebula. Each nebula had 30 each of 120s subs. The other 2 panels, top right, bottom left, were only 5 each of 120s subs due to a rising sun. Gradients, therefore, were an absolute beast to try and tame. But learning new tricks in PixInsight is always fun.
