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

Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, L, vmE in pos 127.1 degrees, first gradually then pslbM to a v feeble nucleus; 4' long, 40 arcseconds broad, has a star 11m preceding."

Hartung notes: "In a field with a few scattered stars on a very faint ground is a moderately bright lengthened haze at least 5' x 0.5' in pa 130 deg rising somewhat to the axis but without a bright nucleus. 20cm deals fairly well with it and 15cm shows a faint streak."

GALAXY

RA: 21h36m27s - DEC: -54o33'20" - Magnitude: 11.4 - Size: 7.3'x1.2'

Tel: 12" S/C 218x - 346x - Date: 21 August 2009 Seeing 5.7

A very lovely slender, quite outstanding galaxy. A prominent 10 magnitude star on the south west edge of the haze give the impression of a supernova linker in the outskirts. With high power the surface brightness became granular. A lovely bright and one of the best examples of a edge on galaxy.

1998 August 22

22 August 1998, Farm site, Meade 8" with a 18mm wide angle & 26mm Plossl, 36' fov, Sky Conditions: Clear 7 to 8 magnitude

Large, bright beautiful spindle galaxy. About 4 in length will fit into the field of view, so I estimate it about 6 to 7 arc minutes. Bright stars to the east following with some more bright stars to the north and some haziness around. Near the west edge but still inside this galaxy a few faint stars can be seen.

2006 June 24

Alldays

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

Conditions: Good

Very much elongated in a NW-SE direction. Just slightly brighter to the middle and running out more thinner to the NW. The SE side is fatter and rounded more off. A minute star can be seen embedded into the NW half of the galaxy halfway between the point edge and the nucleus.
