Combination of 2, 3 minute exposures, Meade 416XTE.
300mm f/6 newtonian at prime focus.
Abell 66 is a fairly large, and very low surface brightness planetary nebula in eastern Sagittarius, about 3 degrees north-west of the globular cluster M 75. The magnitude is quoted as 14.9, but the light is spread out over and area 4.5 arc minutes in diameter. A VERY vague hint of the planetary was visible in a 17.5" telescope under 7.4 magnitude skies. However it was a very dubious sighting, only brief glimpses with averted vision were possible.
