NGC/IC Project Restoration Effort

===== NGC 7689. The RC3 position (from ESO) is correct (barring an error in ESO, of course), while RC2 gives the wrong RA. Oddly, there is nothing in the GSC at either position, though ESO-LV repeats the ESO position and gives plausible data for the galaxy there. ----- The incorrect RA in RC2 is from the NGC, GC, and finally JH whose RA is just 30 seconds too small. While I haven't yet looked at the sweep, I don't think that this can be wire error -- at this declination, the minimum wire error would be 48 seconds. So, it looks to be a simple digit error somewhere in the observation/reduction "pipeline". The surface brightness of the galaxy is apparently a bit too low for the GSC, by the way. The object itself is a beautiful SB(sr)bc I-II spiral, and has entries in the 2MASS lists, UCAC, GSC3, and UB10. I've adopted the position from 2MASS PSC.

===== NGC 7689 30" (10/13/15 - OzSky): at 303; bright, very large, oval 3:2 or 5:3 NW-SE, ~2.7'x1.8', contains a relatively large brighter core that is only weakly concentrated. Spiral structure is evident. A short arm is attached on the southeast side of the core and extends east. A second arm appears to be attached on the southwest side of the core and extends southeast. Finally a third arm appears to the north of the core. The halo is patchy or mottled on the northwest side (HII regions or parts of an arm). A mag 11 star is 2.2' E of center, a mag 15 star is at the north-northwest edge of the halo and a mag 16 star (or stellar knot) is at the northeast edge of the halo.
