Description:
Every once in a while, I like to try to squeeze every photons out of my
TV-102 and not let any single photon escape ...
Pick this dim and teeny 15" (smaller than even the Blue Racketball) to test the
limit of TV-102. Looked very dim at 30x and looked like a star popping
in/out. At 60x, 5 stars form a pentagon (SAO186790, 186783, 186800, 186802,
GSC6644:489) with PN closed to 186802, still very dim and looked like unfocused
star. Pentagon still fit in FOV at 110x, still looking only like unfocused
star. Still unfocused star at 175x! Definite PN form, oval shape at 220x but
still very small. Hint of nearby but faint 12.8th magnitude star (GSC
6857:2006) popping in/out with averted vision. Glimpse of the 12.9th magnitude
central star popping in/out with averted vision, saw it 3 times during the
sesssion. No color detected but looked like gray smudge. Too dim and tiny to
be much fun in TV-102. “Houston notes that this somewhat challenging planetary
can be seen as a nebula in a 10-inch, in which the disk appears gray and ill-
defined.” Umm, he obviously didn't have the TV-102 to try with ;-).
