Corwin's Notes
=====
NGC 4410. JH described this as "eF, vL, R, gbM; 2 1/2' diam" from a single
observation on 28 January 1828. But the pair of galaxies is just an arcminute
across. Did JH actually see one of the NGC 4411 pair (which see for confusion
of its own)?
I frankly doubt it. The surface brightness of the NGC 4410 pair is
considerably higher, and JH's position is much closer to them than to NGC
4411. There is also no problem in JH's position. The offset from the nearest
"standard" star in his sweep, 12 Virginis, is +12m 55s, -1d 15m 25s; so, the
reduced position for NGC 4410 is within 2 seconds of time and 6 arcseconds of
the position that JH himself reduced considering all the stars in the sweep.
This pair of galaxies is interesting in its own right as an interacting pair
with a very faint distorted corona. There is a bridge leading to IC 790 and
CGCG 070-079 beyond that, also connected by a bridge. All of the galaxies
have similar redshifts in the 0.023 to 0.026 range, so they are all part of
the same group.

NGC 4410
24" (6/4/16): at 225x; NGC 4410 is a merged, interacting pair at 20" separation in a common halo. NGC 4410B, the brighter eastern component, appeared moderately bright, small, round, 20"-25" diameter (the halos overlap), very small bright core. NGC 4410A, the western galaxy, appeared fairly faint, small, round, 15" diameter, weak concentration, lower surface brightness than NGC 4410B.
IC 790 = NGC 4410C, located 1.8' ENE, appeared fairly faint, small, elongated 3:2 E-W, 24"x16", very small brighter nucleus. A very diffuse tidal plume (not seen) connects IC 790 with NGC 4410A/B. CGCG 070-079, 2.3' ENE of IC 790 (and also connected by a tidal plume), is faint, small, elongated 2:1 WNW-ESE, 24"x12".
17.5" (3/24/90): fairly faint, fairly small, elongated E-W, weak concentration. This double system (NGC 4410A and 4410B) was not resolved. NGC 4410A is the brightest in a quartet with IC 790 1.9' NE and CGCG 070-079 4' ENE (not seen). NGC 4411A lies 9' S. IC 790 appeared very faint, very small, elongated E-W.
