Welcome To The Kopernik Astronomical Society

  • KAS members wrapping up at the Cherry Springs Star Party in 2017.

KAS Weekly Observing Plan

Each week KAS Member, Robert Byrnes publishes an observing plan to be used at Kopernik Observatory during the Public Friday Program. This is a great list to use each week for any observing challenges.

The Universe’s Splendor Is Within Your Reach

The KAS is always interested in getting new members of all levels of background and interest in Astronomy! We believe in letting members pursue their interest in Astronomy at whatever level they would like. We have members who are Beginners, Celestial Gazers, Astro Photographers,
Theory People or Experienced Observational Astronomers.
There’s So Much to See In the Dark!


2019 KAS Cherry Springs Star Party Adventure

The KAS is venturing to Cherry Springs State Park in Pennsylvania for the 2019 Cherry Springs Star Party May 30th – June 2nd. This is an annual adventure undertaken by the KAS, and typically we have between 8 – 15 active members attending the star party.  Cherry Springs offers some of the darkest skies in the northeast, and CSSP typically brings in between 200 – 500 participants.

2019 KAS Messier Marathon

Planning is underway for the 2019 KAS Messier Marathon.  This is a great opportunity to view all the objects catalogued by Charles Messier that took him 24 years to observe.  Messier catalogued objects that he originally thought were comets, but could not confirm them as such.  Basically these objects appeared to him as “faint fuzzies” but unlike comets, they never moved. His list of 110 objects were almost considered a hinderance by him.

Today, this list of objects are the most accessible and easiest to view objects in and around our galaxy.  About 10 of them can be spotted with the naked eye, and the rest are all findable with even a fairly modest telescope.  Every year during the new moon dark window in March, all but a few of these great objects are observable in just one night.  This year, 2019 there will be two windows to attempt “mostly” Messier marathons. In March the best chance will be the period surrounding March 9/10, and A second window will be March 30/31, 2019.  Despite the likelihood on an incomplete Marathon, seeing so many Messiers in one night would be a lofty accomplishment!

There are objects that will be impossible to see or extremely hard (usually 3-4 of them – see the SEDS article below). There are also darkish windows around those two dates where partial marathons will also be possible.

The objective here would be that the KAS gather on the first clear night during that window at Kopernik Observatory & Science Center.  So far there is interest with a a few KAS members.  This will be a Kopernik Astronomical Society ONLY event.
