Choosing Your First Astrophotography Camera: CMOS in 2026

If you’re stepping into astrophotography, the camera choice can feel overwhelming. Here’s a straightforward look at what matters and which direction to go in 2026.

CMOS has won

CCD sensors are essentially discontinued for amateur astronomy. Every major manufacturer — ZWO, Player One, QHY — now builds exclusively on CMOS technology. Modern back-illuminated CMOS sensors like the Sony IMX571 and IMX533 deliver lower read noise, faster readout, and better quantum efficiency than the CCDs they replaced.

Cooled or uncooled?

For deep-sky imaging with long exposures, a cooled camera is essential. Cooling the sensor to -20°C or lower dramatically reduces thermal noise, giving you cleaner data. Cameras like the ZWO ASI2600MC Pro or Player One Poseidon-M Pro include TEC cooling that holds a stable temperature throughout your imaging session.

For planetary and lunar imaging, an uncooled camera is perfectly fine. Planetary imaging uses very short exposures (milliseconds), so thermal noise isn’t a factor. The ZWO ASI662MC or Player One Mars-C II are excellent choices here.

Mono or colour?

Monochrome cameras with filter wheels produce the highest quality images, but require more equipment and processing time. A colour (OSC) camera is simpler to use and still delivers stunning results, especially with modern dual-narrowband filters like the Antlia ALP-T or Optolong L-eXtreme.

Our recommendation for your first deep-sky camera: the ZWO ASI533MC Pro. Its square sensor eliminates amp glow, it has near-zero read noise, and the 1-inch format works beautifully with fast refractors.
