ASTRO: M7

Another by-catch of my photon fishing in Namibia was M7.
It probably has the brightest stars in any compact open cluster, Guide 8
gives mag 6 to mag 8 for the brightest members.

Taken from Tivoli farm with an ASA 12" astrograph at 1069mm focal length on
an ASA DDM85 mount, Atik 383 camera 4x5m Lum, 2x5m RGB each, all binned 2x2.

Well done. The cluster really stands out much like it does visually. I
have trouble getting cluster stars to stand out from he background.
Though, as you mention, this one is far brighter than normal. Too low
for me here of course.
