| Globular Cluster M5 |
The Globular Cluster M5 resides 24,500 light-years away in the constellation Serpens. At an age of 13 billion years, it is one of the most ancient globular clusters known,
forming only a few billion years after the Big Bang. M5 is one of the 160 globular clusters known to reside in a spherical halo around the Milky Way's galactic center. M5 is
one of the larger globular clusters, containing about 100,000 stars within a diameter of 165 light years.
The image above combined 24 minutes red with 36 minutes each of green and blue exposures. A QSI-583wsg camera was used through a 305 mm AP Ricardi-Honders
Astrograph at f3.8. The image below combined 30 minutes luminance exposures with 9 minutes of green and 15 minutes red and 12 minutes of blue exposures. An
ST10XME camera was used through a TEC 140mm refractor at f7. Both images were obtained at the Hidden Lake Observatory.
