Getting Started in Astronomy

Many people find our night sky filled with stars fascinating and would like to know more about it but perhaps don’t know how to get started. If you count yourself amongst such people, below is some brief advice on getting started in astronomy as a hobby at little to no cost.

Firstly, you should learn your way around the night sky using some of the resources listed below. Then move on to binocular viewing if you have access to a pair. And be sure to contact one or more of the local amateur astronomer associations listed below as they are filled with enthusiastic folks who would love to share their hobby of astronomy with you.

Learn your way around the night sky

Even if you plan on eventually buying your own telescope (or have one already), this is an important and necessary step for the amateur astronomer.  You can’t point a telescope at the object you want to view if you don’t know how to navigate the sky (and you can’t troubleshoot issues with a go-to telescope properly either).

You’ve probably looked at the stars and noticed a few patterns already and can probably name a few constellations. Start with those you know and then use some of the resources below to build your knowledge of the stars.

Don’t know how to identify any constellations? Take 15 minutes and run through this interactive sequence and you’ll know the Big Dipper, Orion, and Cassiopeia.

Printed star maps

Sky and Telescope offers free sky maps in their Getting Started in Astronomy guide. There’s a map for each month of the year plus a map of the Moon.

SkyMaps.com also offers free maps that you can download each month. These maps are intended for certain hours of the evening of the given month, but they are particularly useful because: (1) they show the position of the planets in that month and (2) they include a list of viewing highlights for the month.

Example of a monthly map available from SkyMap.com which includes viewing highlights for each month.

For a map that is sturdier and will work for all months of they year, you can use what’s called a star finder or planisphere. The National Research Council and RASC offer a star finder that you can print, cut out, and glue on to sturdy paper. This star-finder allows you to turn its disc to set it to the date and time at which you’re observing. (Please note that when using it during Daylight Savings Time, you’ll need to subtract an hour). This video gives a good overview of how to use a star finder.

If you have a smartphone or tablet, then you can download apps that will show you what stars you’re looking at. You simply point your device at the region of sky that you’re looking at. There are many such apps available at a variety of prices; the ones listed below are free to download.

Star Chart is available on Apple and Android devices.
Google Sky Map is available for Android devices.

Planetarium software

Planetarium software shows you what the sky will look like at any time from any location on Earth. It’s useful for looking ahead to see when astronomical objects will be visible or for checking back in time to see what that bright star you saw the other night was. It’s also fun just to peruse it to get to know the night sky.

The fabulous program Stellarium does all of the above (and more!) and it’s free as well. Download it and install it on your computer (there are Windows, Mac OS, and Linux versions) and consult the Quickstart Guide in the wiki for assistance if needed.

Get out your binoculars

Odds are you may have a set of binoculars at home or know someone whose binoculars you can borrow. If not, a basic set suitable for astronomy (7X50 or 10X50) doesn’t have to cost too much. There’s many beautiful astronomical sights that can been seen with binoculars. Binoculars are particularly useful for wider objects such as the Moon and nebulae.

If you get serious about binocular viewing, you may that your inability to hold the binoculars nice and steady is becoming a nuisance. While binocular stands can be purchased, you may be able to rig up your own and save yourself some money.

Seek out local astronomers and viewings

There are several groups of amateur astronomers on Prince Edward Island. These groups welcome those who share their interest in astronomy and provide opportunities for viewings through their telescopes.

If you’d like to learn about astronomy while helping out with community events, consider signing up for UPEI’s Community Astronomy Network.

Of course, while you’re visiting UPEI Astronomy’s website, be sure to check out information about our viewings.
