More Saturn and Globulars 05-06/07/2019

Here is another image of Saturn, with the PD this time. Not brilliant, but at least you can see the Cassini division in the rings this time.


Also observed 3 globulars, NGC6284, NGC6235 and M22. The first 2 were difficult but the real find was M22, which I didn’t know anything about! Its brighter and larger than M13! See for a comparison under similar conditions. M13 was alot higher up of course.

“M22 is a very remarkable object. At 10,400 light years, it is one of the nearer globular clusters. At this distance, its 32′ angular diameter, slightly larger than that of the Full Moon, corresponds to a linear of about  97 light years; visually, it is still about 17′. It is visible to the naked eye for observers at not too northern latitudes, as it is brighter than the Hercules globular cluster M13 and outshined only by the two bright southern globulars (not in Messier’s catalog), Omega Centauri (NGC 5139) and 47 Tucanae (NGC 104) – this is the ranking of the four brightest in the sky.”
