Frequently Asked Questions about Star Parties

What is a star party?

A star party is a gathering of amateur astronomers who set up their telescopes and observe the dynamic night sky. Students and their families are invited to come and participate as well. It is a great way for non-astronomers to see things they don't typically take the time to ponder.

How much does it cost?

A Star Party is a no-charge event and open to astronomers and non-astronomers alike. We do ask that schools provide refreshments for astronomer volunteers, since they use up a lot of energy standing out in the cold all night.

When is the best time of year for a star party?

Star parties are best scheduled during first quarter and waxing gibbous Moon. During full moon, the moon is so bright it obscures a view of other celestial objects and even the Moon is best viewed when NOT full. The spring and fall are usually excellent times to hold star parties, as the night time temperatures are reasonable and it gets dark early enough. However, star parties can be held at any time of year.

Should I bring a flashlight?

If you do, bring only small ones to keep the stray light low. Flashlight etiquette - point it toward the ground only. Cover it with several layers of red cellophane or use a red LED light. Red light doesn't affect our adaptation to night vision. You will find that after a few minutes in the dark, without looking at the white beam of a flashlight, you will be able to see enough to walk safely on a paved path toward the astronomers. It takes 3 minutes to reach 30% of full night-vision-adaptation; 30 minutes to reach 65%; but 3 hours to reach full night-adaptation. One flash of light in your eyes will start the process all over again! So, please be respectful of others who are trying to get night-adapted!

What kind of clothing should I wear?

In Winter the rule is dress warm – have a few layers – bring a hat and gloves. Temperatures in Winter months can get very low in the evening.

In Summer the rule is wear long sleeves, and apply bug spray before going outdoors.

Remember that you may be outside for several hours during a clear night, when it is significantly colder or cooler than during the day. It is best to dress in layers, so you can remove or add as needed.

What if there is bad weather?

Clouds or extreme low temperatures would cancel observing. We will consult local weather forecasters and make a decision by 2:00p on the day of the star party. To get a GO/NO GO status on the star party contact your school coordinator.

What can I expect to see?

Many beautiful objects, including:

• Planets, such as Jupiter, Mars, and Saturn.
  
• The Earth's Moon.
  
• Nebulas, Galaxies, and so much more.
  

How can I learn more about shielding techniques for outdoor lighting?

What information is available about the Amateur Telescope Makers of Boston?

The following are useful documents:

• Who We Are brochure
• Interested in Astronomy brochure (designed for 14" x 17" paper)

A note to members running a star party - please print copies of either document and make them available at the star party to help promote the club.
