The amount of technology we now take for granted is astonishing; a typical smartphone has a dazzling array of components and functions including digital camera, GPS receiver, computer, internet browser and email. For anyone with an interest in science, this effectively means you have a mobile laboratory and research centre packed into a small portable box that fits in your pocket. With a few modifications, your smartphone can be converted into a laboratory instrument wh Read More →

Getting Started with Astrophotography

Capturing the beauty of the universe presents a serious challenge for even the most experienced photographer.  No matter how beautiful the finished photograph may be, it often pales in comparison to the real thing.  Taking high quality astronomical photographs requires not only excellent general photography skills, but a fine eye, attention to detail, and of course the right equipment. The good news: with a little practice and patience, anyone can learn how to capture celestial bodies in all their glory!

Astrophotography participants range from amateur astronomers taking photographs of the moon, planets, and stars to professional astronomers mapping and documenting the heavens.  Many amateur photographers strive to capture the beauty of the world they see around them. The surrounding sky certainly provides a wealth of photo opportunities. And thanks to technological advances, the cost of equipment have dropped significantly in recent years so this is a great hobby for even the tightest of budgets.

Stuff to Consider

One of the chief challenges of astrophotography is of course, the relative lack of light.  While some celestial objects such as the moon and stars are sufficiently visible to produce quality photographs using basic equipment, other heavenly bodies are simply too gar away to generate much light.  Therefore most astrophotography is dependent upon the use of time exposures to accumulate a sufficient amount of light required.  Those photographers who are unaccustomed to using long exposures will need to do some experimenting in order to find the perfect balance.

Other photographic techniques can also make astrophotography more rewarding.  For instance, most photographers will need to mount their camera to the focal point of their telescopes in order to get a clearer view of the heavens and an accurate representation of what they see when they peer through the glass.  Many quality telescopes come with a camera mount built in, and this is certainly a feature to look for when shopping for a new model.

Special film can also help to capture the stars, moon, etc.  Film photographers can use special emulsions designed for low light conditions, while digital photographers can look for special cameras designed to overcome the challenges of night photography.  When shopping for a new camera, astrophotography buffs should look for models capable of supporting very long exposure times and multiple exposures.  Successful astrophotography can require multiple exposures up to 20 or more, so this is a particularly important feature to look for.

Last but certainly not least, photographers with an eye to the heavens will want to look at the array of filters designed to make astrophotography more rewarding.  Filters designed to reduce fogging and other distortion can make a big difference in the look of the finished photograph.  There are many filters designed for use in astrophotography, and it is a good idea for photographers to test several models in order to find the most effective solution.

The challenges encountered when trying to capture the night sky can vary from place to place, and it is important to choose filters designed to address those issues.  Amateur astronomers in some parts of the country may be troubled by light pollution, while others may live in areas prone to haze, fog and other atmospheric conditions.  Finding a filter designed to address these common problems can make the night sky clearer, and photographing your part of the universe a great deal more enjoyable.
