Steve's Notes

===== NGC 7678 48" (10/27/16): at 610x; very bright, fairly large, slightly elongated SSW-NNE, 2.0'x1.5'. Contains and small bright core and an extremely bright, very small nucleus. The core is elongated WNW-ESE and appears as a weak bar. A bright thin arm is nearly attached on the east side of the "bar" and swings counterclockwise to the south of the core. This arm is well defined and brightest on the southwest end [~30" SW of center]. The northern arm is only visible at its root near the west end of the "bar" as well as a small, detached piece on the northeast side of the halo [30" NE of center]. The galaxy sits within a bright isosceles triangle of mag 11/12 stars. The observation was made in good seeing but through thin clouds. 24" (10/5/13): NGC 7678 is in the Arp group of "spiral galaxies - one heavy arm", which is evident visually. At 260x the galaxy is beautifully framed with a thin triangle of mag 11.3/11.4 stars to the north and a mag 12 star off the south end. It appeared fairly bright, moderately large, elongated SW-NE, ~1.8'x1.3'. Contains a brighter elongated core that increases to a very small brighter nucleus. The "heavy arm" is visible on the south side as a thin, shallow arc in the outer halo and brightens right at its western tip. 13.1" (9/9/83): faint, moderately large, diffuse, slightly elongated ~N-S, 1.8'x1.4', weak concentration. Located within a thin isosceles triangle of mag 10.5-11 stars with the vertex at the south end and height 2.5'. The mag 11 star just off the south end is just 1.1' from the center.
