In HA The Ghost Nebula (designated Sh2-136, VdB 141 or IC 63) is a reflection nebula located in the constellation Cepheus. It lies near the cluster NGC 7023. Looking at the adjacent image, the nebula’s name is easily understood. The Ghost nebula is referred to as a globule (cataloged CB230) and over 2 light-years across. There are several stars embedded, whose emissions make the nebula shine in brownish colour.

The Helix Nebula, also known as NGC 7293, is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.[5] The distance, measured by the Gaia mission, is 655±13 light-years[6]. It is similar in appearance to the Cat’s Eye Nebula and the Ring Nebula, whose size, age, and physical… Continue reading Helix Nebula

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.[3]
