First DSO - M42 Test Shot

Please excuse this, my first DSO. I was out shooting 30 images of the Moon and decided to take some test shots with different ISO to see what the Canon T7i can do. This is a whopping 1 minute total exposure, two 30 second shots with one dark. As you can see after an hour outside I even had dust or lent on the lens. This is the first somewhat successful image of the Orion nebula taken through a 250 mm Canon telephoto lens, ISO 800, f/5.6.

The first step into better DSO images, (I hope).
