It’s a couple of days past the Full Moon, the Moon is waning and the next astro-viewing window is about to open – and I still have images from the last cycle which I haven’t posted.
The window “opens” a few days after Full Moon, with the waning Moon rising later in the evening. It “closes” over two weeks later, as the crescent Moon waxes to First Quarter and gets too bright for serious deep sky observing.
So here is NGC 362, a pretty globular cluster, which I imaged on a field trip with Macarthur Astronomical Society over three weeks ago with no Moon in the sky.
Located adjacent to the Small Magellanic Cloud (but a lot closer), NGC 362 is often overlooked in favour of the much brighter, closer and thus more visually appealing 47 Tucanae situated only 3° away.
NGC 362 is about 10.4 billion years old, making it a relatively young globular cluster. Astronomers know this by the higher metallicity of its stars, compared to other globular clusters.
