Description:
Under these less-than-ideal conditions, I was able to
spot the famous tiny planetary only with GREAT difficulty.
It was invisible at both 20x and 65x (even in the sweet
spot of the higher-power Ploessl), and SEEMED invisible
at 40x in the 12mm Nagler. But a session of slow, heavy
breathing, coupled with fixated averted vision, suddenly
brought out a mag 12(?) star into view just S of M76's
location, and out popped the planetary! (I wasn't hyper
ventilating and hallucinating, I swear. :>) The PN was
elongated roughly 2' by 1' ESE-WNW, and even a hint of
the famous "lobes" could be perceived. Below is a rough(!)
ASCII sketch of the field, with stellar mags noted in (),
for observers cursed with conditions similar to these:
