Tips and Suggestions

Promoting Your Event 


If you're active on social media, use the hashtags #100HoursOfAstronomy and #IAU100 to share your event. We want to help promote it on our channels! 


You can also avail of the IAU100 and 100 Hours of Astronomy logos here.

For large public events, good promotion beforehand will help make the event a success. If you are holding small sidewalk events where you plan to have only one or two people with telescopes, keep your advertising to a minimum. We suggest just turning up with your telescopes and show those in the area the night/daytime sky, but do not forget to register you event here on the 100 Hours of Astronomy website, every event is important, no matter how small!

Promote the event in your own astronomy club first. Getting as many members as possible to be part of the event will ensure a good number of telescopes available for the event. The more the better!


If you regularly hold public events, it is a good idea to develop relationships with local newspapers, television and radio stations, free-lance reporters and editors. It is also important to find all the local online event calendars in your area. It is fairly easy to send out press releases to everyone and to register events on line. You will be surprised at how often major news organisations pick up items from these postings and releases. Be ready if you are called for an interview. Assign a spokesperson for the event making sure they have all the information to deliver a quality interview if required.


Send announcements to local schools through the school office and to individual teachers and the PTA or other parental organisations as well. Many teachers will work with you to coordinate lesson plans or special projects that take advantage of the observing opportunity for their students. Schools often have websites, email lists and on-line calendars – don’t forget to ask them to include your event.

Local libraries can post flyers on their public news boards. They can also reach members of the public that are likely to be interested in getting a chance to look through a telescope. Ask them to work with you, possibly making a display of some astronomy related materials along with a flyer announcing your event. Libraries also use the internet as a resource and can be a great help in reaching the public and alerting them to your event.

Remember, if you are sending your announcement out by email, make sure to ask the recipient to forward it on to others who maybe interested. Simply asking help to spread the word, works!

Stargazing Tips:

Perhaps your 100 Hours activity involved stargazing into the night sky. Enjoying the night sky is simple and straightforward, anybody can take part and no expert knowledge or equipment is needed. To help you make the most of your stargazing, here are ten tips to starting and developing your interest in astronomy.


1. Choose your instrument 

The old saying “the right tool for the job” applies to stargazing, too. Your eyes are excellent instruments for astronomy as you can see a huge amount of the sky and detect moving objects like shooting stars. To see even more stars, consider a good pair of binoculars. These are good value for money and are easy to use. Serious astronomers may like to invest in a telescope. These instruments gather much more light than your eyes, so allow you to see faint objects such as galaxies and nebulae more easily.

2. Choose your location

The ideal location for stargazing is far away from town and city lights as this will give better views of the night sky. However, beginners may actually find it easier to get into the hobby using light-polluted skies, as the dimmer stars are drowned out making the brighter constellations even easier to see. So if you live in a city, do not be put off! Always remember to stay safe. If you go to a remote location try to visit it during the daytime and always let others know your plans. 

3. Choose your equipment

Stargazing does not necessarily require a lot of equipment, but a few items are highly recommended. At the top of the list is warm clothing as it can get bitterly cold at night. A reclining chair will allow you to lie back and stay comfortable. Torches covered in red plastic, or painted with red nail varnish will help you see while keeping your eyes adjusted to the dark. A hot drink and some snacks are advised, as are sky maps, a fully charged mobile phone, and an accurate watch. 

4. Be prepared

Only a small amount of research will let you maximise your stargazing time. Learn what is visible and when. As well as the obvious stars and planets, consider finding out when man-made objects pass overhead, such as the International Space Station. Checking the weather forecast will also save you a lot of frustration if cloudy weather is imminent. 

5. Learn the night sky

Getting to know the constellations is one of the most rewarding parts of amateur astronomy. Tracking down new star patterns will help you find your way around the night sky quickly and before long your knowledge will be greatly increased. 

6. Become a story teller

The constellations come laden with myths and legends that have been told for many hundreds of years. Knowing these tales will allow you to tell stories with the stars, become familiar with patterns in the sky, and make you a hit around the camp fire. 

7. The more you look, the more you see

The secret of astronomy is persistence. If it is cloudy one night, try again the next. Keep observing and build on your experiences. The night sky changes over the year, so there are always new things to look at. 

8. Get involved with other people

There is a lot to be said for enjoying the peace and tranquillity of the night while observing on your own, but stargazing can be a social activity. If you would like to take things further, consider joining an amateur astronomy society. Then you will be able to learn from others and share your new hobby.

9. Keep a log book

Jotting down all of the things you see and notice in a journal will help you to learn and make the most of your observing sessions. In no time at all you will be star hopping from the great nebula in Orion to the Pleiades star cluster in Taurus. 

10. Enjoy it!

Remember that star gazing is fun and simple. Avoid getting caught up in technical aspects if that does not interest you. It is incredibly satisfying to just go outside on a starry night and look up!
