Although a 2.8" wide pair of 6.5/8.5 stars I failed to split this pair.
The fact that I observed them immediately followed the light feast of Alpha
Cent may have something to do with it. I will return.
This star lies close to Hadar, the unsplittable and is easily found by star-hopping in the area of the Pointers. Hartung suggests this star is an easy split and a long period for this pair with little change and an attractive field. Comments: I found the primary a Light Blue colour with its fainter companion to the North. The field is very rich field with a Crux look-alike to the west and a bright star in the eastern segment of the field at low power. HS 3.

Date & Time: 13/5/01 19.15 +10 UT Seeing: 7.5 <1-10 Seeing Scale (10 best)>. Location of site: Sydney, Australia Site classification: Suburban Conditions: Good Temperature: 21ºC Sky darkness: 4.8 <Limiting magnitude> Telescope: Pixie 8’ Dob Magnification: 50x and 200x |
Tight unequal double – no colour noted.
Notes Needed to go to 200x to split this double located slightly south of A and B Cent. If double was any closer the secondary would be lost in the glare.

Date & Time: May 13th, 2001 07:35 UT Seeing: 4 <1-10 Seeing Scale (10 best)> Stability: 7/10 Location of site: Escobar, Argentina Site classification: Suburban Sky darkness: -- <Limiting magnitude> Telescope: Celestron SCT 8" f/10 Eyepieces: Ultima 30 mm, Radian 8 mm, Ortho 12,5 mm (MG) Magnification: 71x, 267x, 163x |
Little bit tight double, only separable
at higher magnifications (as 267x). At this power, any differential colour
is evident, just white (both). A is brighter than B.
