Description:
Could not confirm with alot of certaintly, but did see
noticable nebulosity, even though faint, with and without a
filter. The stars associated with the nebula looked cloudy
with filter and clear without. I would suspect I observed
the brighter western portion of the nebula, which looked
noticably undistinctive as far as true shape. I would say
that better sky conditions would warrant a better look at
this Pne, but I did see some nebula there. A practised eye
is essential for this one.
