Collinder 399 (CR 399) - Coat Hanger

Introduction | Map | My Own Observations | References

On this page I collect my observations of the asterism CR 399, called Coat Hanger, Al Sufi's Cluster, or Brocchi's Cluster, in the constellation Vulpecula/Little Fox.

 

Introduction

The asterism CR 399 is located in the constellation Vulpecula/Little Fox. Thanks to its shape, it is called Coat Hanger. While I was not able to find the Coat Hanger in 2016, I succeeded in 2017 using two approaches: (1) Found CR 399 between Altair and Vega, on half the way is a somewhat lighter star slightly above the direct link (apparently, this is Albireo) below is a double star (Anser), and below it finally the Coat Hanger; (2) you can find the Coat Hanger also using Cygnus/Swan (Deneb, Sadr) and Albireo. Meanwhile, I always search for the Coat Hanger using the second way.

Size: 60' (Stoyan)

My Own Observations

Regrettably, I did not find the Coat Hanger CR 399. Location, observation date, and telescopes used are unknown/forgotten.

In September 2017, I observed the Coat Hanger CR 399 using the Heritage 100P at different magnifications, and particularly with my Leica Trinovid binoculars (Sumène, Haute Loire, France):

In October 2017, I found CR 399 in Mühlhausen/Kraichgau (both binoculars, Leica Trinovid and TS) - and always well.
