RA/DE:  5:34.5 / +22.01=92=20
A large soft elongated glow at 39X that is an easy Messier in the 8".
Not viewable in my 50mm. At 69X a hint of an "S" shape becomes apparent,
and at 125X and above, very easy. A small 13.5 mag star(s) is visible
with an averted view near the center. The actual pulsar, of course, was
not visible (16 mag?) At 125 and 250X some texture (unevenness) is
noticeable which I take as filaments that are better seen in photos. In
the 80mm, the "s" shape was seen at 125x although not clearly defined.
No stars or "texture" seen at this aperture. I wonder at what aperture
the central pulsar, and filaments would really be seen.
