Check our weather and the moon phase
Weather permitting, Saturday Night Observing is from 7pm to midnight where volunteer Staff provide guided tours of the sky.
Check back often for the lastest information regarding programs and news.
Check the phase of the Moon here and
remember, less moon = darker skies which is what you need
to see many deep sky objects such as those found in the Messier
Catalog or the NGC Objects. But whether the Moon is
just a sliver or full, it's always great to see through
As a volunteer organization, we can really only guarantee to answer the phone Saturday nights when we are there. Check back here and our facebook page for the latest information.

CUSTER HONEY BEE CLUB MEET.
Last chance to order your bees for the spring! We'll be taking orders at our February meeting! (Supplied by North Fork Promise Land Apiaries)
Custer's Honey Bee Club is a group of enthusiastic beekeepers and bee lovers who get together once a month to share their honey bee experiences and learn from each other about how to keep bees, sustainable bee practices and hive management. At these informal meetings, you will have a chance to meet and mingle with beekeepers of all levels, from the novice beekeeper to the professional. Custer's Honey Bee Club has a community bee yard and other facilities that allows for hands-on collaborative learning and demonstrations and which is surrounded by a beautiful arboretum. Not yet a beekeeper, but want to learn what beekeeping is all about? Are you a backyard beekeeper looking for other backyard beekeepers? Or a professional beekeeper interested in getting involved with the growing North Fork beekeeping movement? Come join us!
Get a feel for the place and part of our must-see-in-person collection!
