The Christmas Tree Cluster

7 hours of integration on the Christmas Tree Nebula in Bortle 8/9 pulls out a reasonable amount of detail. This is a cropped image, stacked, drizzled, stretched and star processed in Siril, with final processing in Affinity 2 with JR macros.

The Rosette Nebula

The Rosette Nebula. This image has a total integration time of 4.5 hours (individual integrations of 45s at gain 60). Processed in Siril, Topaz Denoise, and Affinity Photo. Bortle 8/9.

M 42–6 hours of integration

6 hours of M42. Processed in Siril and Affinity Photo 2 with JR Macros. Zoom in on the core to see the 4 stars of the Trapezium.

M 42 with JR Astrophotography Macros

I've posted images of M 42 here before. It's a tough object, because bringing out faint nebulosity without blowing the core is a real challenge. There's also a temptation to over process, exaggerating details within the nebula at the expense of losing a more natural image. This image is a stack of 3 hours of 10s and 20s integrations. I stacked and removed stars in Siril. All other processing was done in Affinity 2, using the incredible JR Astrophotography macros. The result is an image with the core intact and subtle details of the nebula visible. I think it looks as if M42 and the Running Man are sailing on a stormy ocean. Again--full credit for this image goes to JR Macros!
