Description

I continue my quest for finding and processing rarely imaged galaxies in the Liverpool Telescope database.

This is an RGB image of NGC3507, and probably the best image available of this galaxy so far.

It looks like it has two centres but I expect that one of them is a bright star in our own galaxy

This can be read at New General Catalog Objects (http://cseligman.com/text/atlas/ngc35.htm#3507):

NGC 3507 (= PGC 33390). Discovered (Mar 14, 1784) by William Herschel. A 13th-magnitude spiral galaxy (type SB(s)b) in Leo (RA 11 03 25, Dec +18 08 08).

Historical Identification: Per Dreyer, NGC 3507 is "considerably faint, pretty large, round, suddenly brighter middle small star, 9th magnitude star attached 25°".

Physical Information: A face-on barred spiral, paired with NGC 3501. Based on recessional velocity of 980 km/sec, about 45 million light years away, in fair agreement with a redshift-independent distance estimate of 65 million light years. Given that and apparent size of 3.4 by 2.9 arcmins, about 45 thousand light years in diameter.

Filters and exposures used (from 2015 01 24 - 2016 03 31):

sdss-r 17 x 90 s (red channel)

Bessell V 8 x 90 s (green channel)

Bessell B 13 x 90 s

sdss-g 6 x 90 s (stacked together with Bessell B for blue channel)
