Andromeda constellation and M31
This is a recently taken shot, from a series of images of constellations imaged whilst I was on holiday in Berdun, a small village near Huesca, in the Aragon region of northern Spain, in September.
The area has no light pollution and the skies are clear for more than 100 nights every year, with stars visible to below 8th magnitude and the Milky Way is visible from 30 minutes after sunset.
This is a single image of 150 seconds duration at ASA 800, taken with a Canon 350d and a 100mm f/2 lens set at f2.8.
Because of the small sensor of the 350d the effective focal length is around 140mm.
The camera was mounted on the Society's own AstroTrak TT2230X driven camera mount
Imaging was done just on the outskirts of Berdun well away from any streetlights, to ensure a reasonable quality image.
The image has been scaled down from the full resolution of the camera [about 10MP] to nearer 2MP.
The image was shot in RAW and then lightly processed [levels and curves'] in Paint Shop Pro X3.
