Open Cluster NGC 6802 Near the Coathanger Asterism

NGC 6802 is a tight little open cluster right next to Brocchi’s Cluster (a.k.a. Coathanger Asterism) in the constellation Vulpecula. I always picked this up on wide-field shots of the region, but this is the first time I put the big scope on this target. Dreyer’s original description of this cluster was Cl, L, vC, E 0deg, st 14…18 which translates to cluster, large, very compressed, extended to zero degrees, stars magnitude range from 14 to 18.

ARP 212 (NGC 7625) Irregular Galaxy in Pegasus

Here is another galaxy from the Arp Atlas of Peculiar Galaxies designated as ARP 212 (also known as NGC 7625). You can just start to make out some of the strange dust lanes in the galaxy in my 59-minute exposure.

Messier 2 (M2) – Globular Cluster in Aquarius

Here is a view of Messier 2 (M2), a bright globular cluster in the constellation Aquarius. M2 is about 37,500 light-years away and is one of the older globs in the Milky Way.

Reflection Nebula NGC 7129 in Cepheus

Here is a 68 minute combined exposure of the reflection nebula NGC 7129 in the constellation Cepheus. It is on the small side, measuring about 7’ x 7’ and has an apparent magnitude of 11.5. Without using filters, I don’t think I could get much more details using my stock Canon 6D but may add some additional time to it.  A young open cluster is causing the surrounding nebula to illuminate.
