Astrophotography Cameras

Below you will find a brief description of the types of Astrophotography Cameras available, and what these cameras are best at.  Many people dive into astrophotography with no previous photography experience (like I did) and have the tall order of learning how to use modern camera equipment.

Astrophotography Cameras: My advice

My primary astrophotography camera – Canon Rebel T3i

I suggest that you decide on what your main photography goals are before purchasing your first astrophotography camera.  With that being said, if you are looking for a quick recommendation to start taking deep-sky photos like the ones on this website, I’d start with an entry level DSLR from Canon such as the Canon Rebel T5.  

You could save some money by purchasing a used DSLR body such as the Canon Rebel T2i, or T3i.  I consider these DSLR’s to be in the “sweet spot” right now that lie within the limits of performance and affordability.  I upgraded my previous astrophotography camera (Canon Xsi) to a modified Canon Rebel T3i in October 2016.

Above: my first astrophotography camera was a Canon Rebel Xsi (450D).  I learned how to photograph deep-sky objects with this camera and even modified the camera myself by removing the IR cut filter.

The Canon Rebel Xsi makes an excellent choice for beginner DSLR astrophotographers, even in 2016 as I write this post.  Also known as the Canon 450D, this camera was the successor to the Canon EOS Xti, and was introduced way back in 2008.  It’s 12.2 megapixel CMOS sensor is small by today’s standards.  For comparison, the latest model in Canon’s

For comparison, the latest model in Canon’s line-up in this category (the Canon T6i) is 24.2 MP!  The limited ISO capabilities of the Xsi are also worth noting, topping out at a measly ISO 1600.   The biggest downfall of a DSLR this old is the amount of thermal noise produced.  These days, Canon cameras are designed to be much better at handling noise using a high ISO setting.

Comparing noise in 6 different Canon DSLR models:

The Canon Rebel Xsi is still a popular choice for amateur astrophotographers


However, despite its age and humble statistics, this camera can produce stunning results that can compete with images of much more expensive cameras.  For the most part, the noise can be taken care of by shooting dark frames, and noise reduction in post-processing.  I have seen used DSLR bodies for the Canon Rebel Xsi sell for as low as $150.  Now THAT’S a steal!

Quite possibly the most important piece of any astrophotography equipment rig is the camera itself.  There are many options available to the amateur astrophotographer and night sky enthusiast.

Brands such as Canon and Nikon have dominated the market for DSLR astronomy photographers in the past, but now camera manufacturers like Sony have also entered the picture with its mirrorless design.  The prices and features of these cameras vary as much as the deep-sky nebulas and galaxies you will image with them.  I have my preferences towards the Canon line of DSLR cameras, but I have done my best to cover the basics of all astrophotography cameras below.

DSLR Camera Filters

DSLR cameras are great at accepting filters to use during your imaging sessions through your telescope.  For example, I use an Astronomik 12nm Ha Filter in my Canon T3i to capture narrowband h-alpha photos.  The 12nm h-alpha filters blocks out all wavelengths of light (including light pollution and moonlight) except for a very narrow band of data in the hydrogen alpha spectrum.

Speaking of light pollution, astrophotographers in the city can benefit from LP (Light pollution) filters for their DSLR camera.  The filter I currently use for all RGB (color) imaging is an IDAS LPS (light pollution suppression) filter made by Hutech.  This clip-in filter does a great job at blocking stray light from street lamps, exterior lighting, and car headlights.

Types of Astrophotography Cameras

There are a few options available when thinking about taking pictures of the night sky.  The main type of camera I focus on my astrophotography is a DSLR (Digital Single Lens Reflex) camera.  Other options include CCD (Dedicated, Cooled Astronomical Cameras), Point and Shoot Digital Cameras, and Webcams.  Each type of camera has it’s strengths and weaknesses, whether it’s performance, cost, or ease of use.  The reason I currently prefer using a DSLR camera for my astronomy imaging is the convenience, flexibility, and cost.  I may advance into a dedicated astronomical CCD Camera in the future, but for now, I am still getting the results I want with my Canon 450D.

Choosing the Right Camera for the job

The type of camera you will use depends on what you intend to photograph.  Because I mainly shoot deep-sky astronomical objects, a DSLR that I could attach to my telescope via a t-adapter was the logical choice.  The DSLR also allows you to attach several different types of lenses to it for landscape astrophotography projects.

If you prefer to focus on taking pictures of the planets in our solar system, a webcam may be a better fit for your needs. If you are not interested in all of the technical settings and advanced controls included in a DSLR camera, a Point and Shoot model may be all you need for your landscape astrophotography goals.  If you are a serious amateur astronomer who wants to take your deep-sky astrophotography to the next level, the CCD camera is likely in your future.

Deep-Sky Astrophotography

This is the act of photographing deep-sky objects in space such as galaxies, nebulae and globular clusters.  These objects are usually cataloged as Messier Objects, NGC (New General Catalogue) or IC (Index Catalogues).  This is the realm where I spend the majority of my time.  DSLR Cameras and CCD Cameras are the 2 main options available for this type of astrophotography.  A tracking telescope mount is required to compensate for the rotation of the Earth, and the apparent movement of the night sky.  Without an Equatorial Mount, you will experience star trailing in exposures longer than 15-10 seconds. An example deep-sky astrophotography is this image of the California Nebula.

Landscape Astrophotography

Landscape astrophotography has gained popularity over the years with the increasingly affordable DSLR’s available.  These cameras are much more sensitive to light than ever before, and nobody can resist the allure of an image of the Milky Way!  This type of photography can also include shots of constellations, planet conjunctions, the moon and more.  This type of photography has quickly become a close second behind my interest in deep-sky imaging.  Attaching a camera lens to your DSLR is necessary for a wide field view of space, rather than connecting the camera to a telescope.

Solar System Imaging – Planetary Astrophotography

I began my photographic journey with this type of imaging.  My first shots were of the Moon through my Orion 4.5 Reflector telescope.  I would use my Point and Shoot Canon Powershot hand-held through the eyepiece for pictures of the Moon, Jupiter, Saturn, Mars, and Venus.  For the best results, astrophotographers will take short videos of the planet they want to capture, and stack the best frames together using Registax or a similar software. The reason for this method is to compensate for varying levels of transparency in the Earth’s atmosphere.  Some of the best planetary images in the world were taken using an inexpensive webcam.

Narrowband Deep-Sky Astrophotography

This is where it gets interesting.  Narrowband imaging is used by professional astrophotographers around the world, including on photos taken by the Hubble Space Telescope!  The concept behind this type of photography is to shoot your deep-sky object through different filters that only pick up certain wavelengths of light. This is beneficial for several reasons, among them is being able to capture images under heavy light pollution.  This is usually done with a cooled CCD camera with an attached filter wheel.

No matter which camera you use, there is a steep learning curve to overcome before achieving high-quality images like you see on Astronomy Picture of the Day.  I encourage you to join your local astronomy club, or one of the many astrophotography communities on the web for specific advice about your astrophotography camera.
