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 "F, lE, vlbM, 25 arcseconds, has a star 15th mag in it, excentric."

From: "Neat Southern Planetaries - V."

NGC 3149 (10037-8025) is a galaxy that lies near the same field of NGC 3195. It can see in the same field if the planetary is placed at the bottom SE edge of the eyepiece, with the galaxy being near the edge in the NW. At magnitude 13.1 it is clearly visible in a 20cm., subtending a circular size some 2'x1.9' min.arc. I could see no detail in the faint 'smudge', in what I describe as another typically unexciting galaxy. This object is not listed in Sky Catalogue 2000.0 or Sky Atlas 2000.0. Both the NGC and RNGC description is F,S,LE, VLBM,*15INV 'Faint, small, little extended, very little brighter in middle, 15 stars involved.'

HJ 5444 (10318-8155) The pair is bright and wide, and is listed as magnitude 7.0 and 9.5, separated by 41.9"sec.arc. at position angle 235O. Measures in the last 80 years have shown little change. The last measures in 1983, as quoted in the WDS96, gives a separation of 41.8"sec.arc. with a position angle 223.5O. Later observations have give the spectral class an upgrade in temperature, and the primary is now considered a B5 subgiant star of luminosity class III-IV, instead of B3. Based on the common proper motions of the two stars it is likely just an optical double star. The pair is visible even in a 7.5cm. My own observations describe the colours as bluish and yellowish. A neat pair!

R133 (09432-8120) has magnitudes 9.5 and 9.5 was first discovered by H.C.Russel from Sydney Observatory on the 26th May 1880. His observation is given as 3.5"sec.arc PA 44O. In 1983, the separation was measured at 3.65"sec.arc. while the position angle is given as 46O, indicating little change. This is a delightful even pair, with yellowish components. As both have similar common proper motions, it is likely that these stars maybe associated. If it is a true binary, the period is probably very long.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a unverified southern object.
