Description

Backyard photo from a SA star tracker, Canon 400mm lens and canon Ra. I have been looking forward to my first attempt M42. This is the result. Its a wider field than usually seen because thats the longest focal length I have, but also I was happy with the result and didnt want to crop. This gives more emphasis to the stars and particularly surrounding clouds. A more conventional framing, though still wide, mild cropped verson is in the shown in the revisions. I used  14 hours of 2 minute frames, and half an hour of 20 second frames for the core. I also collected 6 hours of Ha but in the end only used this to marginally improve definition. A lot of time spent in processing on  starfields particularly trying to control the star size and colour. Comments most welcome.
