Front Range Astronomy Community


The Front Range Astronomy Community is made up of amateur astronomers along and around the 'Front Range' of Colorado and southern Wyoming. While many of our members belong to the Northern Colorado Astronomical Society (NCAS), Longmont Astronomical Society (LAS), Boulder Astronomy and Space Society (BASS), The Little Thompson Observatory (LTO), Denver Astronomical Society (DAS)Cheyenne Astronomical Society (CAS), and other clubs & organizations around the 'Front Range' of Colorado, membership in one or more of these clubs is not required to be on FRAC. 


Members of the FRAC group communicate with each other on topic such as:

  • Special astronomy events
  • Locations and times of dark sky observing gatherings
  • Observing tips and techniques
  • Sharing astrophotos taken by members
  • Equipment recommends and troubleshooting
  • DIY projects
  • Astronomy history
  • ...And Much More


The FRAC was originally created (March 1999) and conceived by Archer Sully with an interesting charter:

"...It is a list for observers in the area. The idea is to promote cross-club observing sessions and communication."

Note that FRAC is a mailing list, not a club.
