Once upon a time not so long ago, the best CCD cameras for astrophotography required serious cash. In the early days of this technology, in the late 1990s, such cameras were incredibly cumbersome, expensive and difficult to use. Fortunately the technology has moved on rapidly and today we are spoilt for choice when it comes to finding the best CCD camera for astrophotography. 

Unlike normal digital cameras, a CCD camera is specifically designed to work with telescopes, and is optimized for photographing deep space. 

Today there is something for almost every budget and experience level. This of course means it can be difficult to actually make a decision on what to buy. In this guide, we share our pick of the eight best CCD cameras for astrophotography (including some that actually use CMOS sensors), covering all aspects and budget levels. 

We also suggest three conventional cameras at the end, that are a sensible choice for astrophotography if you want a picture that can take pictures when not tethered to your telescope.

Choosing a CCD camera for astrophotography

Today CCD/CMOS digital imaging cameras generally come in two main types: Mono B&W or one shot color. The mono camera type produces images in grayscale only, so to produce color imagery you'll need a set of RGB filters. One shot color cameras can, as the name implies, produce color images straight off the bat. 

Color imagers are without doubt easier to use if you're after color photos. However, because of the way they one shot color cameras work, the finest imagery still comes from mono cameras employing color filters. To be honest this is an issue only the most demanding astrophotographers need worry about – these days there is a much smaller difference in image quality .

Another consideration with CCD and CMOS cameras is the size of the sensor and the pixel size of the sensor. Your choice will depend on what you wish to photograph. For nebulae, galaxies, nightscapes and so on, you'll need a large sensor giving a big field of view. For lunar or planetary photography, you'll want a smaller sensor giving a smaller field of view. 

Modern cameras can work in two modes: either taking single still frame images or high speed video streams. The former is generally employed for imaging nebulae and galaxies while the latter is used for imaging the moon and planets.

Almost all of the cameras you can buy today operate via a high-speed USB3 interface. In general all will come with their own operating software, however there are many third part packages available, and many of these will actually be better than the manufacturer-supplied software.

Let's get started with our roundup of the best CCD cameras for astrophotography. We've included a range of different astronomical cameras geared to different tasks, from lunar, solar and planetary imaging to long-exposure deep sky photography. Regardless of what you wish to do there is an affordable camera out there that will unquestionably meet or exceed your expectations.

Reasons to buy
+Specialized full-frame sensor+30x Live View & viewfinder zoom+4K video
Reasons to avoid
-CR3 (RAW) files not yet supported by some astro software -35mm sensor needs large image circle

Canon's last dedicated astrophotography camera was the Canon EOS 60Da back in 2010 – a capable but crop sensor camera, and built on the back of decade-old DSLR tech. By contrast, the Canon EOS Ra is an astro camera with a huge 30.MP full-frame image sensor – itself a luxury in the world of astrophotography. However, this is no stock sensor; the infrared-cutting filter is modified to enable four times the amount of hydrogen 656nm alpha rays, enabling a higher transmission of deep red IR rays without the need for specialized optics or accessories. It also boasts an incredibly useful 30x zoom on both the rear screen or electronic viewfinder, as well as the ability to record crisp 4K video. Some of the more boutique third-party software is still playing catch-up to Canon's RAW files, and you'll need to make sure that your optics can support the image circle of the larger sensor (though there are in-camera cropping options), but otherwise this is a clear winner for shooting the stars.
