Small portions of the NVSS and FSC sources are contributed by the
companion galaxy NGC 3769A at RA = 11 37 50.32, DEC = +47 52 53.8.
NGC 3769-This is another highly inclined spiral, this time with a bar running
across the field. A point-like source is located near the center of the bar
and may be identified as the nucleus; there is not a strong gradient in the
diffuse light leading up to this source. Prominent dust lanes are visible
against the bar south of the nucleus, and several knots (again, probably young
clusters) may be seen in association with the dust.
Karachentsev 294 [with NGC 3769A]
April 28/29, 1979
NGC 3769 forms a close pair with a
companion (NGC 3769A; Sm; not in the RSA) which
is evidently at the same distance judging by its
similar resolution into stars and HII regions. The
separation of the pair is 1.2'. The individual v_o
redshifts listed by Karachentsev are 791 km/s
for NGC 3769 and 845 km/s for its companion.
At the mean redshift distance of 16 Mpc (H = 50)
the projected linear separation is very small at
6 kpc. It can be guessed from the distorted
morphology that a close encounter is, in fact, in
