i already had a few days to play with the camera, to know how the filterwheel works, how to take exposures etc.
tonight i had the chance to photograph a part of cynnus.

i photographed it from my normal holiday location in south limburg in holland.

ive used 5×10minute exposure with the canon 70-200 2,8 IS on 135mm and baader 7nm Ha filter
the chip was cooled to -10 and there were no dark frames used.
