CR399 - Open cluster in Vulpecula
Open Cluster CR399
  • Description: Open Cluster CR399 in Vulpecula, also know as "The Coathanger Cluster". South is up in this view which is how it would look in a widefield telescope but inverted compared to the view through binoculars. Clouds and humidity terminated this shot! All three red exposures were fine but the telescope dewed up during the last two green exposures and clouds shut it down after a single blue shot. The clouds added an interesting aura to the image so I have posted it! Other items of interest in this image are open cluster NGC6802 to the right of CR399, and Sh2-83 - a compact emission nebula left of centre near the bottom of the image.
