Globular Cluster Palomar 2 (PAL2) in Auriga

The dim reddish object in this image is the globular cluster named Palomar 2 (PAL2). It is one of a group of 15 globular clusters discovered by examining survey plates of the Palomar Observatory Sky Survey in the 1950’s. It lies about 90,000 light years away and partially veiled by the Milky Way running through the constellation Auriga. It has an apparent magnitude of 13.04 and measures about 2.2’. It took me six nights of attempts on this – I hard a hard time spotting in test exposures to get it centered.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, Antares Focal Reducer, ISO 3200, 32 x 60 seconds using Backyard EOS with darks, bias and flat frames, guided using an Orion 60mm guide scope with an attached ZWO ASI290MC camera. Image Date: December 20, 2017. Location: The Dark Side Observatory in Weatherly, PA.
