2013 03 12 – NGC 7006 (H 1.52/C42)


Most globular clusters are located within the Galactic halo. NGC 7006, however, resides in the outskirts of the Milky Way, roughly 150k light-years away from the Galactic center. Although my observation was in the early morning hours of March, this stellar formation actually makes a terrific October target. It’s small and dim, which can make it difficult to locate. Look for neighboring star patterns and then increase your magnification to help locate it. You’ll see a dense core at all apertures with a faint halo evident in 8” scopes. My 16” f/4.5 reflector at 75x revealed a smooth, round 1.5′ disk with a brighter dense center. Increasing to 150x, it appeared slightly mottled with an absence of resolved stars. I attempted to increase magnification to 225x but the cluster became too dim to pull out more detail. My best view was at 150x with a 42-degree TFOV.
