Welcome to the official website of the Cumberland Astronomical Society.  We are a group of amateur astronomers based in Gallatin, Tennessee.  Our focus is to bring astronomy to the general public in the upper middle Tennessee area.  We hold several monthly events at local schools, libraries, and parks. Everyone is welcome, so please click the "EVENTS" link for dates and times.

Please enjoy the video below which gives a brief overview of the Cumberland Astronomical Society.

There was an error on our Website. Tonights star party is supposed to be a club party
Sorry for the confusion.

The new moon every so often lines up with the sun so that somewhere on the earths surface
An eclipse happens where the moon blocks some or most of the sun. We were lucky to have this
happen over our skies. Below are some the views of the sun from the 23rd by members and friends

After much editing Jewel Mclerran is putting together a series of video's to show what we
came across when attempting to collimate a Celestron 8se with a Hotech collimator. In this
series of videos club member David Craig brought in his Hotech Collimator. One thing you
may notice is that we were unable to bring the scope to focus. Instead of giving up we went
ahead with the steps just to see what all is involved. Hope you find these videos helpful

Ted Ed posted another video on distances in Astronomy. This exact question has come up many times.
Hope this video Helps clear things up.

Lonnie Puterbaugh would like to announce:

Lunar Eclipse viewing via NASA TV with live feed from yours truly and the TAC minivan on site at
Marshall Space Flight Center.

From about midnight Monday night/Tuesday am until about mid-eclipse or a little later, NASA TV will be showing
the eclipse live from Marshall Space Flight Center with a live feed from yours truly and the TAC minivan on site
(weather permitting). I will be using (2) APO refractors -- a TEC 140 (high magnification) and a Takahashi 106
(full disk) mounted tandem with video cameras for the feed.

The TAC cameras have IR response which is capable of showing craters on the moon through moderate to dense cloud
cover even when the moon isnít visible to the naked eye. It wonít be pretty if I need to do this, but we could
still show the eclipse through the clouds. Right now, the forecast in Huntsville shows heavy thunderstorms during
the day Monday with clear and cool at night!!! It just might present good seeing conditions after dark.

I may take a color cam to show the blood red color.

Any other suggestions for me and TAC?

2012 Observing Resolution -
Start working on your Double Star Award!!!

Albiero in Cygnus

One of the advantages of membership in the Cumberland Astronomical Society is that we are a member of The Astronomical League, which is composed of over 200 astronomy clubs from all over the United States.  Several of these member societies sponsor Observing Clubs, which award pins and certificates upon completion.

This month, we'll focus on the Double Star Club, which is managed by Nashville's own Mike Benson of Barnard-Seyfert Astronomical Society.

The purpose of the Double Star Club is to introduce observers to 100 of the finest double and multiple stars in the heavens. You don't need a large, expensive apochromatic refractor to view the objects on this list since a small refractor, Newtonian reflector, or Schmidt-Cassegrain will do just fine. All objects on this list were originally observed with a three-inch refractor using between 75X and 150X. Again, this program is meant to allow you to enjoy a different aspect of our wonderful hobby, and not to test your equipment.

Double star observing can be very forgiving. You don't need the darkest skies, the clearest skies, or even a moonless night to observe many of these objects. Some can be observed from your backyard under moderate light pollution, some can be observed under less than transparent skies, and some can even be observed with the moon up. However, as usual in astronomy, the best results can be obtained under optimum conditions. The point is, always try for the best conditions, but if you don't have them, don't worry about it. You can still enjoy this program.
