| Bob Hogeveen's Report (n.b.hogeveen@hetnet.) |
|
One of the occasions on
which I visited the Southern
hemisphere was in 2001, "around" the Total Solar Eclipse of June 21. It
was a trip I made with some other Dutch observers to Zambia and
Zimbabwe. We
observed the Eclips in Zambia and then went of to Zimbabwe where spent
a few
days in Mana Pools N.P. and where we enjoyed the clearest, darkest
night one
can imagine (and moonless!). There were no real
astronomical scopes at hand exept one C5 and besides a few
looks through this C5 I made my own observations with my Swarovski AT80
birdwatching scope (which made overtime during the day as well as you
can
imagine). My fieldscope is not very suitable for observing doubles
because of
it's limited magnification (max. 60x) and besides that most of the time
during
the clear nights I concentrated on the many spectacular deepsky objects
which
can be seen in the area of Vela, Carina and Centaurus. In Crux it were of course
the Jewelbox Cluster (NGC4755) and the conspicuous
Southern Coalsack which took first attention. But the doubles were not
forgotten. I had made a list of some easy to spot-and-split doubles and
indeed
some of the S33-project doubles in Crux were also observed. In the end
I
observed four doubles in Crux on that occasion, Alpha, Beta, Gamma and
Iota. Of Beta I did not observe the B-component which is given in the project (mag. 11.4 @ 44.3") but another star which sits 270" to the west of A and is mag. 8.8. The information I had indicated that this was the "B-star", or at least a star that is paired with Beta-A. Now I tend to believe that it is just a field-star. Greetings from Holland and have fun with, and clear skies for the new project. Bob www.homepages.hetnet.nl/~nbhogeveen |
