Description:
Alpha Libra (Zubenelgenubi) can be very easily split.
M5 can be found from betha libra. This globular cluster was fainter
than I expected. It may be due to poor seeing. However; it is still
easy to find. Cannot see a definite central core.
M4 is also an easy target but it seemed fainter than M5 to me. Cannot
observe it for long time because the clouds blocked the way.
