PLEASE CHECK OUR WEBSITE , FACEBOOK, OR YOUR EMAIL FOR CHANGES DUE TO WEATHER CONDITIONS

Sunset is at 7:38 PM and it gets dark quickly.  Although the daytime temperatures may be warm, the temperatures can become quite chilly as the night progresses into the night so be sure to bring along a warm coat, cap and even gloves are essential to help you enjoy the evening. A reclining lawn chair and blanket would be a nice as well. Of course the observatory classroom will be a nice spot to warm up a bit and visit with friends. 

This is a special members only event coinciding with the Messier Marathon. The goal of the evening is to locate as many of the 110 M objects compiled by French astronomer Charles Messier in the late 1700's. Visible in smaller or moderate sized telescopes, the deep sky objects of the Messier Catalogue of star clusters, nebula and galaxies are popular viewing targets. Members are also welcome to just come and do some casual observing if they choose not to try the Messier Marathon. 

This event will run all night until sunrise, with members being asked to bring a pot-luck style dish/desert/snack to share. The club will provide drinks/coffee/hot chocolate also.  Page 10 of our March 2026 Newsletter  has links to charts of the Messier objects and the Sequence you should be observing them.  Starting with the early evening objects that set quickly and working your way across the toward the ones rising in the east. We sent out an email from the Night Sky Network as a reminder and ask for a head count if you plan on attending this event. Please respond to it if you plan on attending.

Some tips for a successful Messier Marathon quest.  

1. Bring your telescope with a variety of eyepieces.  Several objects can be seen with binoculars.

2. Battery Power Supply for your scope and charging cords, we do have a limited number of extension cords for AC power.

3. Bring some detailed Star charts of a good Astronomy app.

4. Print out the Sequenced Log Sheet to check off your progress. The log sheet is arranged in the order you need to search for objects, starting with the ones that set soon after sunset.  

5. Some Pencils and a hard surface clip board to write on.  ( Pens don't work well if its cold or damp )

6. Comfortable Lawn chair, Warm Jacket and Cap as temperatures drop.

7. Bring a dish or snacks to share in the potluck to keep your energy up.  

We reserve Observatory nights nearest the New Moon for our members.  This allows our members to work on their various observing projects, do some astrophotography, share ideas and help each other with their goals. Members may bring your own telescope or enjoy viewing with some of our members.  You can bring along family or a friend if they want to observe with you. As a member you may bring family members or a friend that wants to observe with you but not large groups. Please keep minor family members within your observing area with a supervising adult.
