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

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, lE, pgbM, 30 arcseconds long."

NGC

Described as "pretty bright, conciderably small, slightly elongated, growing pretty gradually brighter towards the middle."

Modern observations

(unknown)

This lenticular galaxy lies in Pavo, glows at magnitude 12.4 and measures 4.3' by 2.3'. In a small telescope, it appears as an oval smear of gray light set in a pretty starfield.

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (218x, 346x)

Very small soft little round cotton ball. It shows of a very bright nucleus although small. A 6.9 magnitude star can be seen about 7 arc minutes to the west which conected the galaxy with faint stars just like the old pocket watches conects with a short chain.
