Position: RA1353 DEC+11:14
Personal "rating" (at this aperture, and sky condition): A-
This is the best example of an edge-on galaxy I can think of.
Brilliant core, and wafer thin edge on. Very high surface
brightness, due to the compactness. Was visible, although not
as pretty, in 7" stopped-down aperture. Best observed at a bit
under 200X, but nice at all magnifications until you run out of
light. Thin-ness was reminscent of Saturn's rings when edge-on.
Thought I saw a dark lane running along axis with averted vision
at higher power, but it could have been an illusion. In the same low
power field as another Virgo galaxy, round.. not edge on like this
one. Bright, thin edge-ons like this are show stoppers! Also observed
NGC4958,4666,4536/4527,4526,4535,4608,4429 but was less impressed...
during this same session.
