Hi everyone,
here's my first image of the Great Nebula in Orion (M42) with the modified Canon 300D. I did the image last night between Twilight and Moon rise, and just before the weather turned ugly again.
The image is composed from 6 x 3 minute exposures (18-minutes total) using ISO-200, on the 12-inch f/5 telescope with the Baader Coma Corrector. The images are dark-subtracted, flat-fielded and bias adjusted.
The core area of the nebula is composed from 3 x 15 second exposures used to mask out the over-exposed core in the deeper image.
Images were processed with IRIS with final adjustments in Photoshop and Noiseware CE.
There is a higher resolution image here

Hope you all like it
