NGC 6027 (Seyfert's Sextet)
NGC 6027, LEDA 56579, MCG+04-38-010 (in Seyfert's Sextet)
Type: galaxy (in group), S0
Mag: B=?, V=14.2
Size: 0.8′ x 0.4′
PA: 85°
History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 6027 is the brightest galaxy in Seyfert's Sextet. There is some confusion about the designations for the six objects in the modern catalogues, but they are fairly easy to sort out. Nevertheless, I have retained the original letter designations assigned by Carl Seyfert in his 1951 PASP paper, in spite of my "rule" mandating positional notation in multiplets.
I also find it curious that Stephan saw only one of the galaxies here. As well as NGC 6027 itself, Seyfert's "a" and "b" are probably bright enough to be seen visually, especially in the 70-cm reflector that Stephan was using.
Note also that Hickson and a few others considers "e" to be simply a tidal extension of N6027. This it may be, but I've retained the separate listing.

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "13.3M; 2.2' x 1.2' extent; sextet of faint SP GALs and EL GALs may be seen on excellent night as soft, unresolved glow in 8-in.; 17.5-in. with P-filter shows sprinkle of individual, unresolved glows; reference-BCH-III-1793."

Steve Coe, observing with a 13" f/5.6, notes: "I saw three galaxies with direct vision at 165X, they were all small and pretty faint. One more galaxy could be detected with averted vision only."
