This picture was taken with my Canon 450D. But now this camera is modified. We remove the IR filter. The photo is the result of 19 frames of 1 minute of exposure. ISO 1600. 20 darks, 20 flats and 20 offsets. I put a filter Celestron UHC / LPR. The photo was processed with Deep Sky Stacker and Photoshop. This is the nebula Messier 8 also called Lagoon. It is an emission nebula located in the constellation of Sagittarius. It is at a distance of 5,000 light years.
