Introduction | Map | My Own Observations | References
On this page I collect my observations of the open star cluster IC 4756 in the constellation Serpens Cauda.
The open star cluster IC 4756 in Serpens Cauda (tail of the snake) consists, according to Karkoschka, of few, inconspicuously scattered stars and is rather an object for opera glasses or binoculars. Stoyan describes it as "loosely distributed", but also as "having clear-cut borders." For the eVscope, the cluster is too large.
Size: 70' / 60' (Stoyan/Karkoschka)
Distance: 1,600 / 1,400 light years (Stoyan/Karkoschka)
Rating: * (Stoyan)
IC 4756 (top center) belongs to the constellation Serpens Cauda, but is close to the constellation Eagle and above Scutum. M 16 (lower right) also belongs to the constellation Serpens Cauda, but is close to the constellation Scutum/Shield. (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
