Wide-field astro is tough; expecially when there is illumination present -you need a long enough exposure to get the stars, but not too long that any light polution gets overexposed. IMO-next itme point the camera directly at the north star so you get at least one non-moving star, or piggyback mount thte camera on a scope that can track the sky so you get nice bright circular stars of all brightnesses and tons of detail.
Also, the contest rules would have allowed you to edit out the hot/cold (red/blue)pixels in the photo. 4 |
