Our two work experience students, Harry and Peter from Sydney Technical High School at Bexley used an avi file captured from a low cost security camera attached to a telescope to make this image of the beautiful nebula M42. The video of 400 frames was scanned to reject frames contaminated by cosmic rays, satellites and asteroids. They then aligned and stacked 396 frames and subtracted the noise via a dark frame. To finish they used Photoshop Elements to stretch the levels. Not bad for year 10 students! (tongue in cheek as it is indeed SUPERB, well done boys)

This is however the benchmark provided by the fabulous Dr David Malin using the 4m AAO telescope at Siding Spring NSW.
