These two images were taken a few months ago when the constellation Orion was in the eastern/southeastern sky. Both imaging sessions were tests of my recently acquired Nikon D850 and of the Siril software package.

The first was taken with a 50mm lens to show all of Orion as well as the neighboring features. The image is a stack of 32 frames @ 60 seconds, f4, ISO 1600, and shot on a Nikon D850. The images were processed in Siril–a tool I’m still learning to use–and the final result nicely shows the Orion molecular cloud complex (or, simply, the Orion complex). From the Wikipedia article:

The Orion complex includes a large group of bright nebulae and dark clouds in the Orion constellation. Several nebulae can be observed through binoculars and small telescopes, and some parts (such as the Orion Nebula) are visible to the naked eye.

The second image was taken a few nights later with a 180mm telephoto lens and is looking at the Witchhead Nebula (IC 2118), located very near Orion–and is also faintly visible in the previous image.  This image is a stack of 38 frames @ 60 seconds, f4, ISO 1600, and shot on a Nikon D850. As before, the stack of images was processed in Siril. From Wikipedia:

IC 2118 is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in the constellation of Orion.

I have been happy with the results on the Nikon D850 for capturing astro images and equally pleased with how easy it is to use Siril in post processing.
