RA: 00 : 14.9 Dec: -39 : 11 Type: Sc or SB(s)m
RV: +129 km/s Distance: 7,000 kly Apparent Dimension: 32.4 x 5.6 arc min Brightness: 8.8 mag
Discovered by James Dunlop on August 4, 1826 (Dunlop 507). Cataloged as h 2315 by John Herschel in 1847, and as GC 27 in the 1864 General Catalogue. Usually regarded as a member of the Sculptor Group (or South Polar Group because of its situation near the South Galactic Pole), this galaxy is listed as a Local Group member by Mateo (1998) (http://www.iceinspace.com.au/forum/#mateo1998) who gives a distance of only 5.4 million light-years, compared to the value of 7 million ly given elsewhere.
Captured 10/9/2010 between 8:30 and 11:00pm
GSO 200mm RC with Wo F2 reducer
QHY 8 OSC
2hr 20m in 14 frames
Processed Pixinsight for DBE and PS CS 3
Seeing fair to muddly no moon
Badly framed will need to do again also bad gradient due to seeing and LP from neighbours but first time since July had a chance to get out and do some imaging and first time at this one
C & C welcome as usual
