Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

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.

Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pF, L, R, vglbM, 2'."

Location: Polokwane

16-inch f/10 SCT (127x 290x 462x)

Easy seen as a round to oval north-west to south-east glow against the back ground. The surface brightness is quite even and the edges flimsy with no bright nucleus. On the western edge a magnitude 11 yellow star can be seen.
