On this page I collect my observations of the open star cluster IC 4665 in the constellation Ophiuchus.

 

Introduction

The open star cluster IC 4665 in the constellation Ophiuchus can, according to Stoyan, already be seen with the naked eye as a faint glow. The cluster is too large to be seen well in the eVscope, it is more of a "binoculars object".

Size: 70' (Stoyan)
Distance: 1,200 light years (Stoyan)
Rating: *** (Stoyan)
