Stephane Javelle discovered IC 4630 = J. 3-1400 on 27 Jul 1903 with the 30-inch refractor at the Nice Observatory. He recorded "F, R, 20", stellar nucleus of mag 14." and measured an accurate position. VV 852 is the category of "Jets and Tails without Visible Cause"

400/500mm - 18" (7/12/10): faint, fairly small, elongated 3:2 ~N-S, 0.6'x0.4'. Sharply concentrated with a very small bright core. Forms the vertex of a flat isosceles triangle with a mag 10 star 4.4' SSW and another mag 10 stars a similar distance northeast.

600/800mm - 24" (6/30/16): at 322x; fairly faint/moderately bright, fairly small, slightly elongated N-S, 25"x20", very small bright core and stellar nucleus. I wasn't confident about seeing the tidal tail to the south. A mag 10 star is 4.4' SSW (brightest star in a small asterism) and another is 4.3' NE.

LEDA 1783536 was also picked up 6.6' ESE. It was extremely faint (V = 15.6), very small, round, 10" diameter, low surface brightness with no concentration. Situated 25" S of a mag 14.5 star and 1.6' W of a mag 13 star.

24" (7/14/15): at 375x, fairly faint, small, slightly elongated N-S, ~22"x16". Contains a bright stellar or quasi-stellar nucleus. I had a couple of definite "pops" of the tidal tail extending to the south.

24" (7/24/14): at 375x, this post-merger system appeared fairly faint, fairly small, slightly elongated N-S, 0.4'x0.3'. Strongly concentrated with a very small bright core containing very bright, sharp stellar nucleus. With careful viewing, there was a very strong impression of an extension (tidal plume) extending south. The narrow tidal tail extending northeast on the SDSS image was not seen.
