Astrophotography is one of the most important branches of photography that helps scientists and astrologists to identify the objects of the night sky. It is one of those activities that created lots of job opportunities for people in 2020.
Astrophotography is not as easy as it shows. It needs lots of knowledge and experience to handle its complicated tips and tricks, and beginners can attend a photography course to learn everything they need to know about astrophotography. The astrophotography tips in this article apply whether you want to shoot deep-sky objects with a DSLR camera and telescope or with a simple camera lens on a tripod. But first of all, you have to know what is astrophotography.
Astrophotography is capturing pictures of the objects of the night sky, such as the Sun, the Moon, planets, and galaxies with special equipment.
Just as Wikipedia says, astrophotography, also known as astronomical imaging, is photography of astronomical objects, celestial events, and areas of the night sky. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, astrophotography has the ability to image objects invisible to the human eye such as, dim stars, nebulae, and galaxies.
Astrophotography Tips
- Choose an Area of Interest
The first step to start astrophotography is choosing your area of interest. Astrophotography has so many different areas including solar imaging and Milky Way landscapes. Each of these areas involves its own special set of skills, equipment, and techniques and needs a particular knowledge and talent. For instance, the photography equipment for capturing a lunar eclipse is distinct from what you need for a long exposure image of an emission nebula. For starting astrophotography, you must choose your field and focus on it in order to have a better experience of learning.
Note that the night sky is diverse and full of billions of stars and planets. This diversity determines your type of astronomy subject, the equipment you purchase, and the camera setting that you will use. This is a reason why beginners must know every astrophotography type with details.
- Types of Astrophotography
- DSLR Camera and Lens on Stationary Tripod
This is the type of astrophotography that focuses on nighttime landscape photography, which is incredibly popular these days. Whether you capture a shot of the Milky Way raised over a desert landscape or a portrait of the Winter constellations, they all fall into this category. Some of the examples of this type of astrophotography include Night Sky Time Lapse, Meteor Shower Composite, Milky Way Photography, Constellation Composite, and Moon Phase Landscape.
- DSLR Camera and Lens on Tracking Mount
This is another level of landscape astrophotography, in which the photographer collects light over an ultra-wide area of the night sky using a wide-angle lens. Astrophotographers can use a tracking mount to have exposures of 1 minute or more for collecting a much deeper view of the sky.
This type of astrophotography includes Deep Milky Way Photo, Wide Field Deep-Sky Image, Solar Transit (Solar Filter), Solar Eclipse (Solar Filter), and Total Lunar Eclipse.
- DSLR Camera attached to Telescope on Tracking Mount
This type of astrophotography is also known as prime-focus astrophotography. In prime-focus, the camera is attached directly to the telescope focus draw-tube, and the type and size of the telescope optical design determine the focal length.
It includes Deep Sky Imaging (Galaxies, Nebulae, Star Clusters), Planetary Imaging, Solar Imaging, and Detailed Moon Surface Imaging.
- Point and Shoot Camera through Telescope Eyepiece
It is known as Eyepiece projection astrophotography and involves aligning the camera lens with a telescope eyepiece for utilizing the magnification of the eyepiece and/ or Barlow lens.
This type of astrophotography is useful for planetary astrophotography and includes Solar Transit (Solar Filter), Planetary Imaging, Solar Imaging (Solar Filter), and Moon Surface Imaging. But note that it won’t work for Deep Sky Imaging.
- Own Your Camera and Tripod
Once you chose your area of interest, you must afford the DSLR camera with a tripod that best suits the type of astrophotography that you chose. Camera and Tripod are the most important factors in astrophotography, and beginners must choose a suitable one in order to have a successful profession.
A good camera for astrophotography must have high quality and a perfect lens to capture thousands of stars in the night sky. The number of stars that blink in an astrophotographer’s camera is incredibly more than the stars that you can see with naked eyes, and this fact can shock any beginner in the first place.
- Take Your First Shot
After affording your suitable camera and tripod, it is time to capture your first shot. It is better to practice the techniques at home before venturing out to a new location in the dark.
First of all, you must take a look at the weather forecast and find out a night with clear or mostly clear weather.
Then you must take a look at the moon phase for finding the best situation. Keep in mind that nights of the New Moon are best for astrophotography, and nights of the full moon are worst to shoot on.
After finding the best night for shooting, check and make sure that your tripod is locked securely and aims your camera towards the brighter star in the night sky. Set your camera to Manual mode and your lens to manual focus in order to have full control of the light you let into your camera.
- Choose the Right Exposure
One of the most important tips in astrophotography is choosing the right exposure. Astrophotographers must be careful with the exposure and use it in the right way to have a great view of the night sky.
Beginners must know that after 15-20 seconds, the images of the night sky will show stars trailing and must shoot exposures as long as they can before the stars begin to trail. One of the best ways to do this is by using the 500 rule as a point of reference. In this method, the photographer divides the focal length of the camera lens by 500 to bring the exposure back to the normal level in post-processing.
Astrophotography is a complicated type of photography full of challenges and different tricks. Beginners must learn everything and practice in order to succeed. Practice, learn and be confident about what you do to capture perfect shots of the night sky.
