On this page I collect my observations of the open star cluster M
25 (IC 4725) in the constellation Sagittarius.
Introduction
The open star cluster M 25 is located in the constellation Sagittarius and
should be visible to the naked eye as a small nebula patch.
According to Stoyan, it is considered as a "classical object for binoculars,"
which is already resolved into stars in binoculars.
M 25 (IC 4725)
Size: 30' (Stoyan)
Distance: 2,000 light years (Stoyan)
Rating: *** (Stoyan).
