The rewards of astronomy were never more accessible than they are today. The recent profusion of spectacular images, the explosion of knowledge and technical possibilities, the ubiquitous presence of the Internet, and the widespread accessibility to equipment have catapulted popular astronomy into a new era.

Astronomy can be practiced during the day or night. In the daytime, it is possible to observe the Moon, several planets, and our own star, the Sun. It is dangerous to view the Sun directly. Instead, you should project its image onto a cardboard screen using binoculars or a telescope, or install special filters onto a telescope before looking through it. Solar spots, which are dark regions on the Sun’s surface, are easily seen when viewing the Sun using these methods.

At night, the entire sky becomes available for study. Whether poetic notions or scientific intentions fuel your pursuits, you should prepare yourself in advance. For starters, make sure you will be dressed in warm and comfortable clothes: it is surprising how cold you can become when remaining stationary for long periods of time at night, even in summer.

Consider bringing music: it can add to the enjoyment of your stargazing experience.

For more scientific activities, bring a precision watch, a good chair, and small table on which to place your star finder, astronomy books and sky charts. Bring a notebook and pencil to take notes.

A flashlight with a red filter will help you see your way in the dark without blinding your friends or yourself. Make your own red filter using the red reflector from a bicycle, or a piece of red cellophane held in place by an elastic band. These days, hardware stores even sell inexpensive headlamps with red LED light that are tremendously practical for stargazing.

Now that you are all set up, familiarize yourself with the constellations using only your eyes: constellations help guide us to the celestial objects we wish to observe. Once you have learned to orient yourself, binoculars will be very helpful – even professional astronomers commonly use them. Mounted on a tripod, binoculars provide magnificent celestial vistas, revealing the topography of the Moon, the moons of Jupiter, a good number of nebulas, and even some galaxies.

At some point, you will want to add a refracting or reflecting telescope to push your observations to the next level. The most important feature of a telescope is its optical precision of its optical components. Look for well-known brands that have established and reliable reputations. Newtonian-type telescopes are generally more affordable due to their simple design.

At the other end of the spectrum are amateur telescopes that are as powerful as those used by professionals thanks to computers and CCD cameras. In some cases, the telescope can be left outside while you make your observations from inside, comfortably seated in front of your computer.

Luckily for those who do not own a telescope, there are many astronomy clubs with members who share a passion for space and are more than happy to let others look through their telescopes. Do not hesitate to contact an astronomy club: the people are invariably a very welcoming bunch. Not sure how to find a club? Consult our list of links for the one nearest you.

A star finder (also known as a planisphere) is a circular map with an overlay that turns to show – through an opening in the overlay – the region of the sky that is visible for a specified time, date and location. It is an incredibly useful tool for orienting yourself in the night sky, for identifying constellations, and for planning your stargazing night.

Not everybody sees the same stars around the world. What one sees depends on the latitude, so it is essential that you know yours before buying a star finder. For southern Canada, a star finder designed for 45E north is sufficient.

The way a star finder works is simple. The days and months of the year are shown around the edge of a circular base, and the hours of the day are displayed around the overlay. By turning the overlay to line up the time of your observations with the date, the portion o the sky that is visible will appear through the opening in the overlay. All that remains is to hold the star finder over your head and orient it with respect to North.
