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

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 1' diameter; bright, small and round with very much brighter center; 14M stellar core and soft edges."

Steve Coe

Steve Coe, observing with a 17.5" f/4.5 at 100X, notes: "Pretty bright, pretty small, round and has a brighter core at 100X. This galaxy looks somewhat like a globular cluster

Contemporary observations

Pietersburg

16-inch f/10 SCT (127x, 290x, 463x)

Soft round and haze galaxy, which is well outstanding against the star field. The small round bright nucleus is in strong contrast to the rest of the galaxy which show a hazy halo around the core more or less 1' in size (16" - 127x). Towards the NW a 12magnitude star can be seen (16" 290x). The southern side is busy in star light.
