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 5045 may be NGC 5155. JH describes this as "A great cluster, or a surprisingly rich portion of the milky way. It contains 34 stars 11m, and perhaps 150 or 200 more of less magnitudes in the field." There is nothing at his position matching this description, but 10 minutes of time following is a large Milky Way star cloud, nearly a degree across, that might well have been seen by JH. He picked this up in the same sweep as NGC 5155 (which see), so I'm not convinced that he in fact made a 10 minute error. However, unless another more compelling idea comes up, I'm at least going to list this identity.

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 "a great cluster, or a surprisingly rich portion of the milky way. It contains 34 stars 11th mag, and perhaps 150 or 200 more of less magnitudes in field."

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL) S.

NGC 5045 (13h 17m 03s, -63 24.9)

Doubtful Objects Report 4.

Location: Campsite South 23 16 - East 29 26

Telescope: Meade 8" 26mm eyepiece

Bright loosely spaced stars form a large zigzag asterism in appearance, rather prominent towards the east side yet thinly dispersed to the west. Rich field of view.

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (95x, 218x)

Bright, loosely spaced stars, which form a large, zigzag asterism (N-S) in appearance. Rather prominent towards its southern side, yet thinly dispersed to the north. It is a rich field of view, yet a rather difficult object. As stated by Herschel it is either a great cluster or a surprisingly rich portion of the Milky Way. He further noted that it contains 34 stars of perhaps 150 or 200 less magnitudes in the field. A sketch I made, (111x) reminds me of the Apollo Lunar module. A beautiful yellow 6.8magnitude star can be seen towards the south edge. Will go back to this one it looks more and more like a MW patch.
