First light of my new mount Mesu 200 mk2 !!
Really happy when I compare with the same picture last year, under different skies and diferent mount….

NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820.
Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association. (Description credits: Wikipedia)

  1. Congrats for this superb result Jose! The image is so sharp and detailed that you can appreciate really small details, not seen in other reference images. Really well done.
