What is Astrophotography?

Astrophotography is a complex yet incredibly rewarding hobby. It’s the process of taking pictures of celestial objects to capture them in all their glory. To do so, one needs to pair their camera with an astronomy telescope. The telescope acts as an extension of your camera’s lens. It captures light from far away objects and projects a detailed image of them. Your camera then captures this projected image. A decent astrophotography rig can be expensive. However, it can capture some stunningly beautiful pictures.

Keep in mind that taking pictures of the night sky isn’t astrophotography. That’s a completely different ball game that requires specialized cameras, patience, and an insane amount of skill. The beauty of astrophotography is that even an amateur can enjoy it. All you need is the right equipment on hand.

Elements of a Decent Astrophotography Telescope

It goes without saying that you’re going to need a capable telescope for astrophotography. One that is capable of projecting crystal clear images of what it’s pointed at. The better your telescope will be, the more detail you’ll be able to capture in your pictures. Now, there are a handful of factors that determine the telescopic ability of a telescope.

Aperture

The size of your telescope’s objective lens is called its aperture. A telescope functions by allowing light to enter through its lens and then project an image. The more light a telescope can capture through its lens, the more powerful it becomes. A larger aperture means that a telescope will be able to project images that are brighter and clearer. Aperture is important. However, it isn’t as big of a thing as some people like to think. The size of your telescope’s optics can only increase its light gathering capability. The quality of its optics determines how well it can turn that captured light into a clear image. A quality astrophotography telescope should have well-made optics.

Focal Length And Focal Ratio

A telescope’s focal length and ratio are quite important when you’re getting into astrophotography. The focal length of a telescope is the distance between its objective lens and the point at which light rays converge to form an image. Telescopes with longer focal lengths have higher magnification power at the cost of a smaller field of view. Shorter focal lengths have wider field of views but lesser magnification power. Focal length should be kept in mind when shopping for an astrophotography telescope. It will determine how much scenery you can bring in one picture and how closely you can view objects.

The focal ratio of a telescope has a very big impact on your astrophotography experience. This determines the speed of a telescope’s image recording. Faster focal ratios mean that your telescope will capture an image faster and vice versa. A faster focal ratio isn’t necessarily good. The faster an image is captured, the less exposure time it gets. If you plan on taking pictures of deep space objects (which project fainter light) a slower focal ratio will be better. Your telescope will be able to produce a clearer image that you can then capture.

Portability

When it comes to ​telescopes for astrophotography, bigger is better. A bigger telescope is capable of capturing clearer images. However, bigger ​telescopes for astrophotography are bulky and impractical. Especially if you’re into astrophotography. You want a telescope that you can move around with you. Astrophotography often requires you to move around to get the best shot. Sometimes you need to shift your telescope to remoter areas to avoid light pollution as well. Basically, what you’re looking for is a telescope that offers power and is light enough to be carried around easily.

Mounts

To do their job effectively, telescopes need a stable and solid mount. An astronomy telescope is next to useless if you don’t have a mount that offers stable support. There are two popular mount types in the astronomy community; altazimuth mounts and equatorial mounts. While both are great, equatorial mounts are preferable in astrophotography. These mounts have two different axes on which they move. This makes operating them a bit complicated. However, their dual axes allow these mounts to be moved according to the Earth’s rotation.

With a motorized equatorial mount, one can track an object in the sky over a period of time. Astrophotography often requires you to leave your setup pointed at the same object for several hours. In situations like these, an equatorial mount is essential. Otherwise, you won’t be able to keep your lens pointed at what you want to capture.

Adapters

A telescope won’t take pictures on its own. You’re going to need adapters to attach your camera to your telescope. The kind of adapter that you’ll need depends on whether you plan on using a DSLR to take pictures or your smartphone. You can capture decent photos with a smartphone. However, to truly capture what you can see through a telescope, you’re going to need a DSLR camera.

Phone adapter mounts are quite simple to use. They can be attached to a telescope’s eyepiece and then act like a mounting bracket for your phone. They’re often a good option for people who are trying their hand at astrophotography. You can start with a phone mount (which is much cheaper) and then move over to something better if you enjoy astrophotography.

T-ring adapters are designed for attaching DSLR cameras to telescopes. They allow you to connect your camera’s lens to your telescope’s eyepiece. T-rings aren’t that expensive either. However, you need to pick one that fits your camera’s lens perfectly. An adapter that’s too big won’t be able to hold your camera securely. An adapter that’s too small may end up getting stuck to your camera.

Different Kinds of Telescopes

There are two major design types in telescopes; the Newtonian Reflector and the Refractor. Both of these designs take a different approach towards making objects in the sky more viewable. Here’s a rundown on each design’s advantages and disadvantages.

Reflector Telescope

Advantages

  • They have larger apertures. This makes reflectors superb for deep space viewing. Their larger aperture also allows them to capture clearer and detailed images.
  • They don’t experience chromatic aberration. Chromatic aberration can significantly reduce the accuracy of what a telescope is viewing.
  • Reflectors cost less than refractors. They make great beginner scopes since you can get a huge aperture at a very low price point.

Disadvantages

  • Reflectors have two mirrors in them. These mirrors can be misaligned easily if the telescope gets shaken around too much. You need to be able to collimate (realign) these mirrors to keep your telescope accurate. This can bring an added element of technicality for beginner astronomers.
  • Reflectors have an open body that keeps their optics exposed. This means that their optics need to be cleaned and serviced frequently. Also, reflectors need time to let their optics reach the same temperature as their surroundings.
  • The shape of a reflector telescope’s mirror creates a distorted effect at the edge of its field of view. This effect makes objects appear stretched out like a comet.

Refractor Scopes

Advantages

  • Their closed body design means that these scopes never need to be maintained. Their optics are kept sealed inside of their body. This makes refractors easier to use.
  • Unlike reflectors, refractor telescopes don’t have part of their optics blocking incoming light. This lets them capture images with better clarity.
  • Refractors have their eyepiece situated at the backend of their body. This makes them more accessible for people of all heights.

Disadvantages

  • Refractor scopes cost more because of their optics. Larger aperture refractors can become quite expensive.
  • Refractors tend to experience chromatic aberration which can make images look weird.
  • Refractors also weigh more. Larger refractors can be a lot heavier and less portable.

Both telescope designs have their pros and cons. However, we can’t say that one design is better than the other. They both have their qualities, and it all comes down to your personal preference. Some people like refractors and other like reflectors. Trying out both designs can help you figure out which one will suit you better.

Now let’s take a look at some superb telescopes for astrophotography.
