Astrophotography How-To

There are many different types of astrophotography, from wide-angle Milky Way photography to deep-sky photography through an astronomical telescope. The basic elements of this hobby include the understanding of long-exposure images, focus, and image processing.

The following basic astrophotography tips and camera settings can be put into action the next time you find yourself under a clear night sky with your camera. I’ll also show you a beginner astrophotography setup for capturing deep-sky images using a camera and telescope. If I can do it, you can do it too.

Perhaps the intense colors of the Orion Nebula or the glimmering Pleiades star cluster have sparked your interest in astrophotography. Or maybe a haunting landscape photograph dominated by a full moon is more your style. However you got here, I understand your passion.

Night sky photography requires a basic understanding of your camera’s ISO setting and the process of taking long-exposure images. If you are a beginner, I’ve got good news. With an entry-level DSLR camera and a tripod, starry landscapes like the one below are within your reach.

My astrophotography equipment has evolved and expanded over the past 10 years, and the learning process never ends.

Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

Your telescope is a key piece of equipment

Beginner Astrophotography Tips

Ready to give it a go? Below are some ways to discover your own style words. Do one, or better still, do all of them and make your decision at the end of the process.

• We all have to start somewhere. If your passion is strong enough, it will carry you through the steep learning curve involved in astrophotography.
• Early on, I did not have a lot of money to invest in this hobby, and my basic equipment reflected that.
• After collecting at least 20 images look for common themes.
• I purchased a lot of my early items from used astronomy gear websites and classified ads.
• Choosing a camera, telescope, and equatorial mount that delivers the results you’re looking for takes time.

Deep-Sky Setup Walk-through

1. Using a DSLR and telescope allows you to take high-magnification images of jaw-dropping subjects such as the Eagle Nebula.
2. Beginners often ask me how I got started in deep-sky astrophotography with a telescope.
3. DSLR astrophotography is a great way to get started.
4. I walk you through the process of capturing deep-sky astrophotography images using a DSLR and telescope.
5. It’s a high-level overview of the processes involved but should answer many of the questions beginners have about astrophotography.

Choose an Area of Interest

I try to cover all aspects of astrophotography on this blog, but subscribers of my YouTube channel know that I spend more time imaging through a telescope than anything else. Some people prefer different areas of astronomy including Solar imaging, Moon Photography, or Milky Way Photography.

1. What type of astrophotography?

If you’re like me, you love all types of images that involve the night sky. However, a quest for a particular type of image may lead you down a new path that involves a new set of equipment and techniques. For instance, the photography equipment required to capture a photo of a lunar eclipse is very different than what’s needed for a long-exposure image of an emission nebula.

2. DSLR Camera and lens on Stationary Tripod:

Nighttime landscape photography is incredibly popular these days. Most images tagged #astrophotography on Instagram are exactly this. Whether it’s a shot of the Milky Way rising over a desert landscape, or simply a portrait of the Winter constellations, few images capture the mood that a night landscape can. Adding a star tracker to the equation brings landscape astrophotography to another level. A wide-angle lens such as the Rokinon 14mm F/2.8 can collect light over an ultra-wide area of the night sky.

Point and Shoot Camera through Telescope Eyepiece:

Focal lengths vary widely depending on the type of telescope used. A large Schmidt-Cassegrain Telescope may have a focal length of over 2000mm, which is ideal for photographing planets like Saturn, Mars, and Jupiter up close. The process of capturing very small objects (from our vantage point on Earth) is quite different than it is for large ones like nebulae.

A common focal length for a medium-sized refractor telescope is in the 400-600mm range, which is a practical magnification for most deep-sky objects in the night sky. The focal ratio of the telescope determines its ‘light-gathering’ power, and most refractors are in the F/4-F/7 range.
