Description:
In light polluted skies, find Beta Aquarii and head N. 5 degrees.
At x100 (10 mm) lens with a deep sky filter I see
a shirt collar button with flashes of silver from
the hazy globular structure. The surface brightness
reminds me of M31 for some reason, and ansai seem
to reach NE from the object at this power. This
could be due to the light pollution and filters
don't seem to help much. though it resembles
M 13 at this magnification (complete with a
pair of pointer stars on either side) it is
farther out in space.
At x158 (6.3mm)I get a glimpse of the angular
drift of the object, like a NW-SE tilt.
I see a few outliers, particularly one to SW
which shows up large even in photos. If I
use averted vision I see the "swirl" a bit
better. Good view with a light polluted sky and
the Deep Sky filter helps
