This month’s copy of Sky and Telescope magazine suggested that 2 Collinder open clusters low down below Sirius make good targets for binoculars. Sirius currently transits due South at about 0030hrs and is then at its highest. That gives me the best chance of seeing objects below Sirius.
Open cluster Collinder 132 was the higher of the pair.
Here is the sky map from Sky Safari Pro 4:
It was easy to find the small triangle of stars down and to the left from Sirius (containing PI CMa). I could just spot Messier M41 to the right of that. Working down from there, I could find the bright yellow star, Wezen. I could confirm this by seeing two small pairs of objects to the left of it.
Unfortunately, that’s as low as I could go. A neighbour’s house prevented me from getting those last few degrees down to the horizon (green line). I guess that’s the problem with living at a relatively high Northern latitude! There would be no problem seeing Collinder 132 in Tenerife!
