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.
