NGC/IC Project Restoration Effort

===== NGC 5765. This is a double galaxy, found by JH on 24 April 1830. Though he saw both, he provided only a single position for the pair, and -- before the NGC was compiled -- it was seen only at Birr Castle. So, given that Dreyer had only JH's position to go on, he may have simply followed Herschel's lead in GC in listing the two objects under a single number. There are several similar cases in the NGC; Wolfgang Steinicke notes that NGC 523, 2187, 3500, 4496, and 5307 are listed as double objects in the NGC descriptions. This is another case, too, where the "A" and "B" suffixes are confusing. RNGC assigned them in order of brightness, so "A" is the southeastern object. UGC, however, assigned the suffixes in RA order, so that "a" (lower case in UGC), is the northwestern galaxy. Also see the note for IC 1066 and IC 1067 in the "notngc" files.

===== NGC 5765 24" (6/30/16): at 322x; NGC 5765B is moderately bright, fairly small, round, 24" diameter, sharply concentrated with a very small bright core that stands out. Brighter of a contact pair with NGC 5765A 24" NW. The companion appeared very faint, fairly small, elongated ~5:2 E-W, 30"x12", contains a very small brighter core, very faint low surface brightness extensions. 17.5" (4/13/91): NGC 5765 is a very close double system oriented NW-SE. The southeast component (NGC 5765B) is brighter and appears faint, small, round. NGC 5765A is virtually in contact at the northwest end and appeared very faint, small, slightly elongated E-W, low surface brightness. The nuclei have a separation of 20".
