My final compilation for Orion's Nebula. 9 pieces - each with an average of 30 x 300s exposures (1x1) bining (22 hours total integration time) and lots of processing time. For the core of the nebula I used 50x100s exposures and used HDRComposition to bring out the core features.

I learnt a lot about processing mosaics in PixInsight for this project but I am quite happy with the final result considering the equipment used.
