NGC/IC Project Restoration Effort

===== NGC 6559. For some time, I had this as a "double" diffused nebula, taking my own position for the "northwest" part, and Andris Lauberts's ESO-B position for the "southeast" section. Ahem. JH's object is a relatively small nebula centered on a double star, with another slightly fainter star to the southeast. Looking at this again in January 2016, I see that Andris got this right ("3 sts in neby"). I didn't; my apologies. Well, it is fixed now. I've adopted the position of the double star close to the center that JH noted as that for the nebula. I also note that the nebula itself is relatively blue (probably a reflection nebula), while a streamer of red nebulosity appears to the northwest. This in turn leads to a large patch of fainter nebulosity overlaid by twisting bands of absorption. All in all, this is quite a pretty area. See also NGC 7088 for comments by Steve Waldee.

===== NGC 6559 17.5" (7/20/96): at 140x an irregular glow is easily visible surrounding a group of 5 stars and brightest around a 30" pair of mag 9.5/10.5 stars. The 4'x3' nebulosity extends mainly to the west and NW of this pair. Best view probably unfiltered at 140x (nebulosity dims with OIII and similar with UHC), but with a UHC filter a very large hazy nebulosity ~10' diameter stands out to the northwest involving a number of brighter stars. 17.5" (7/17/93): observation made at 100x using an OIII filter: Brightest portion of extensive nebulous complex, most prominent along two converging rows of stars oriented SW-NE and NW-SE. A mag 10 star is located in the second chain. This description appears to describe the large region of nebulosity to the NW of NGC 6559 mentioned in the July '96 observation. 17.5" (6/20/87): 88x with UHC filter: fairly bright, fairly large nebulosity about 5' diameter. Surrounds two mag 11 stars and extending to four or five fainter mag 12/13 stars. 13" (7/16/82): fairly faint, curved strip of nebulosity, includes five stars.
