|Object Type||Globular Cluster|
|Size||12.0' x 12.0'|
With the rising of Ophiuchus comes globular season. The vast majority of globular clusters are concentrated between 16h and 23h RA. In Ophiuchus alone, Messier catalogued 5 globular clusters, most of which are visible to the naked eye under dark skies. M9 is one of the fainter ones, at around magnitude 7.8. Although I have never managed to sight it without optical aid, it is easily visible in binoculars, some resolution is achieved with an 8" telescope.
M9 is situated about 3 degrees south-east of eta ophiuchi in a rich portion of the Milky Way. As a result there are numerous other deep-sky objects in the vacinity and the region well repays any time spent observing.
