Image of the Week

Orion nebula, also known as Messier 42, M42 or NGC 1976.

Canon EOS R5 with a Canon RF 400mm f/2.8L IS USM lens.  ISO 800. 30 sec at f/3.2 . Exposure set manually.

Camera and lens mounted on a Gitzo 1548 tripod with a mounted SkyWatcher Star Adventurer 2i Pro tracker.

This is an image that I captured earlier this year. However, I have used new processing techniques and the Topaz Denoise AI software to reduce the noise from longer exposures. This result is much better than the original processed image using only Adobe Lightroom® and Photoshop®. The detail in the nebula is so much clearer and does justice to the excellent Canon RF 400mm f/2.8L lens. The camera and lens rig took some balancing atop the Star Adventurer and needed an extra counterweight. I was suprised how well the tracker managed the combined weight of lens and camera body.

The Orion nebula is just south of the belt of Orion in the constellation Orion. It is the closest region of massive star formation to Earth. It is 1344 light years away and is some 24 light years across.
