NGC 2506 in colour

[petevasey]

NGC 2506 is a bright (mag 7.6) quite dense open cluster in Monoceros. Low for me, never rising above 24 degrees.  The night of 16th March was promising although with a young crescent Moon. A little late in the year, already past the meridian when the sky was dark enough, so low in the haze and the stars are slightly blurred. Not a focus problem, just down to sky conditions.  But by keeping the exposures short I didn't saturate the stars so was able to show the colours and am reasonably satisfied with the image.  Later edit - a bit more unsharp masking seems to have improved things.  QSI683 on RC10 with SX AO. Luminance 15 x 2 minutes, RGB each 8 x 2 minutes, all binned 2x2.

Cheers,

Peter
