Should You Upgrade To A Camera Instead?

If you are a beginner who enjoys taking pictures of celestial objects, using your smartphone with the use of an adapter can be the perfect way to get into astrophotography.

However, if you are serious about your hobby, you’ll probably consider purchasing a camera instead.

There are limitations to using a smartphone instead of a camera, such as a DSLR, for astrophotography.

These include how you won’t be able to match the quality of images that are produced by a DSLR camera that’s attached to your telescope and equatorial mount so that it can follow the stars.

That said, there are things you can do to make your smartphone work as best as it possibly can ‘“ and produce amazing pictures.

How To Use A Smartphone For Astrophotography 

How To Use A Smartphone For Astrophotography

You’ll need apps

You’ll have to be able to adjust your phone’s settings manually in order to elevate it so that it can match an astrophotography camera.

Some important settings you’ll have to tweak include increasing your phone’s ISO, which is basically how much light hits its sensor.

For astrophotography in the dark, you certainly want the ISO to be as high as possible. An app like Camera FV-5 (Android) or NightCap Camera (IOS) will be helpful here.

Invest in eyepiece filters

These can help to block out unwanted light and also increase the details of what your smartphone can capture.

They are especially useful if your smartphone isn’t equipped with exposure control, bearing in mind that you need to be able to take pictures that dim the light so that the images aren’t overexposed.

An example of a filter is a moon filter that will cut out glare and help you see its details, such as craters.

Consider taking videos

Have you ever felt frustrated that the image of the planet that you can see through the eyepiece isn’t the same as what your phone is taking?

To ensure higher-quality images with your smartphone, you need to stack your images with software later.

This uses multiple photos so that the best result can be derived from them. A smart tip is to record a video clip of the planet with your phone and then use image-stacking software that will use the best frames from it.

Zoom in with a lens

Another important piece of gear that you need if you want to take pictures of the night sky with your smartphone is a lens.

This will help you when it comes to zooming into a celestial object to reveal its color and details. You should use a telephoto lens instead of a digital zoom as that will decrease the quality of your image (via Sky at Night).

This type of lens will allow you to take pictures of various things, such as sunsets and the moon. Of course, you’ll have to use the lens with your telescope so that is definitely a non-negotiable item you’ll need if you want to take pictures of the night sky with your smartphone.

Invest in a tripod

You’d need one for your telescope anyway, so make use of it with your smartphone.

This will ensure that your phone remains steady for long exposure shots, which are crucial for astrophotography. These shots allow more light to enter the camera’s sensor.

Process the pics afterward

As with any astrophotography images, it’s worth putting them through editing software afterward to reveal their best parts.

By tweaking the contrast, brightness, and stacking images, as we mentioned earlier, you will be able to make your pictures look so much better. But be warned ‘“ you don’t want to overprocess your images; otherwise, they won’t look natural.
