Reflection Nebula NGC 7129 in Cepheus | Schulman Telescope

NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. The nebula is rosebud-shaped. The young stars have blown a large, oddly shaped bubble in the molecular cloud that once surrounded them at their birth. The rosy pink color comes from glowing dust grains on the surface of the bubble being heated by the intense light from the young stars within. Ultraviolet and visible light produced by the young stars is absorbed by the surrounding dust grains.

The 0.81 m (32 in) Schulman Telescope is a Ritchey-Chrétien reflector built by RC Optical Systems and installed in 2010. It is operated by the Mount Lemmon SkyCenter and is Arizona's largest dedicated public observatory. The Schulman Telescope was designed from inception for remote control over the Internet by amateur and professional astrophotographers worldwide. It is currently the world's largest telescope dedicated for this purpose.
