Rain and clouds are still in power over the skies of Lijiang so this is another opportunity to share one of my old observation made in Colombia.
|Binocular and eyepiece view comparison|
The first time I saw it I was surfing the sky with binoculars and it seemed just like a tiny and crowded stellar town in the middle of a less starry background due to light pollution. Not far from it, there were others open clusters including the Great Nebula in Carina with its companion clusters NGC3324 and NGC3293; truly a good show for bino-viewers.
Later, despite the heavy urban light pollution and the last brightness of a waxing moon almost ready to set, I got to see dozens of stars in the cluster, in spite of the cheap 20mm erecting eyepiece that comes by default with the Celestron astromaster telescope.
I believe that under darker skies and a better piece of glass, you can manage to see two or three times of the numbers of stars I could make out that night. Of course, even in binoculars, the cluster looks like a lovely bunch of bright lights waiting to be explored more deeply.
