Description

the great andromeda galaxy (M31) and friends @ 400mm focal leght :)
a classic object, that I wanted to shoot again, with the excuse to verify the correction of the field at the edges, now I can reduce to 0.8x the apo refractor 80/480
and I must say, not bad! above all, for just one hour of total exposure and under a dark sky like that of the Italian Western Alps

tech specs: Canon eos 600D full spectrum and 80/480mm super-apo triplet on a HEQ5 mount (about 1h of total exposure time @1600 iso)
Cugn di Goria, Colle di Sampeyre, Italian western alps
