Description

First light of another cooled and debayered canon 450D I've just finished, the weather as been horrible so this is only a very short integration time captured with a 7Nm Ha filter between the passing clouds... it's only 35 min. of data (7x5 min. @ 1600 iso) believe it or not The image is just callibrated with bias frames (25 frames) with NO DARKS or flats.
