Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

Modern observations

Brian Skiff

PK: virreg w/f (?) on NE, br on SW (lobe elong in pa120).

15cm - mod f, vis easily @ 50x. gradual contrast improvement going from DS to

[OIII] filter. 140x: 30" across but not circ. fan-shaped w/sharply-

defined edge on NE, fanning broadly SW. m13 `cen *' nr NE border. m11.5

* at W edge; m14.5 * in SW side of neb. two more *s close on SSE & NE.

BS, 15Oct1990, Anderson Mesa.

25cm - found @ 90x. 180x & 240x show it boxed in among four *s in lousy square.

on SW is m12 *, NE is m13, SE is m14.5, NW is m12.5. the neb is circ

w/m14 cen *. neb fades at edges.

30cm - smlr than -94, but different in character. perhaps elong, but mess of

assoc *s confuses. 40" diam w/vsl concen. edges fades like gx, but I

have gxs on the brain though. CBL, Roof.
