Object data: Galaxy, listed as magnitude
I HIGHLY recommend this object for all instruments. It has
a high surface brightness and certainly could have been
viewed at smaller aperture. This galaxy is tiny, only a few
arc minutes long. (it's listed as 4x2) It is very elongated (mainly N-S) and
looks like an edge-on or irregular galaxy. It has a bright central portion,
with a very slight bulge, however, the extension is easier to see on
the south side, making it appear like a small comet at times!! In fact, it
almost
appeared with averted vision, like the south extension "fanned out" a tad away
from the core!
There was at least one dark lane perceived, one on the east side running
long-ways at the base of the galaxy, however, with averted vision, I could
have sworn there was another one close to running along the center axis.
At high magnification (267x) in the Televue binoviewer, I noted a great degree
of irregularity in the brighter core area, lumpiness-mottling, not sure
what it was. this is a very nice object for suburban skies.
