At the core of astro images is the ability to record the light from your telescope with astrophotography cameras. In the past CCD was considered the gold standard for astrophotography. CCD has predictable signal-to-noise ratio when cooled, and is the camera of choice for most scientific applications.
However recent developments in CMOS technology have led to a rise of excellent sensors which have a much lower noise profile as well as high quantum efficiency (QE). Manufacturers have been able to transition these sensors from high-end DSLR cameras to cooled astrophotography cameras.
Cameras with cooling are best for deep space astrophotography and typically have larger sensors. Cameras with smaller sensors, but no cooling, are best for planetary imaging as well as guiding cameras.
Bintel stock a wide range of cameras for all different applications. It’s important to match the camera to your telescope to ensure the “sampling” is in the right range for what you’d like to do. It’s best to check the camera/telescope combination using our astrophotography calculator here.
Other factors include whether the camera is colour or mono, whether you need filters, framerate and readout speed. Some cameras have additional features for astrophotography built in. It’s worth reviewing the specifications. If you need help choosing the right camera for your astrophotography, we’re happy to help!
