Palomar 2 (PGC 15963 and others) is one of fifteen globular clusters discovered on the plates of the first Palomar Observatory Sky Survey. Approximately 90,000 light-years away in Auriga, it is heavily obscured by dust in the plane of our galaxy. This obscuration dims the brightness by approximately 1.2 magnitudes and blocks a lot of the blue light, resulting in the reddish image.

Luminance – 24x600s – 240 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

360 minutes total exposure – 6 hours
