- 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.

- The telescope should be able to place the target somewhere on the CCD sensor and you can frame the object better, if necessary, by using the slow motion controls on the mount. Once done, a series of short exposures is taken. If you are using the LRGB filters mentioned above you can work with just 180-second exposures.

- Astrophotography - CCD’s: A CCD is a "Charged Coupled Device" and is made of the same material as computer chips. The method behind CCD's uses the same methods for which Albert Einstein won the Nobel Prize, the photo-electric effect. It was discovered that silicone release electrons when exposed to light.
CCD Cameras, CMOS Cameras for Astrophotography
- https://www.highpointscientific.com/telescope-accessories/astro-photography/ccd-cameras
- Astronomy CCD & CMOS Cameras for Telescopes. Dedicated astrophotography cameras are capable of capturing the phenomenal detail and color of faint objects in the night sky such as galaxies, nebulae, and star clusters. These cameras are typically referred to as CMOS or CCD cameras. Long exposures, typically consisting of several minutes, are taken with these cameras.
CCD Astroimaging & Astrophotography Cameras for Telescopes
- https://telescopes.net/imaging/ccd-cameras.html
- CCD astroimaging and astrophotography cameras will capture a still image of the night sky in user-specified exposure lengths. With post processing work, these images can be layered and stacked to create stunning and detailed pictures of nebula, star clusters, galaxies and planets. Available in both full color and black and white (monochrome) sensors, CCD cameras for …

- Film astrophotography began in the late 19th century with photographs of the moon, sun, and bright stars. Film then was thousands of times slower than it is today. While film became faster and faster, the technology itself changed very little. Then, in the 1970s, professional astronomers began using CCD cameras instead of film.

- While you could easily cherry pick some counterexamples, in general it's still objectively the case that CCDs are better suited for low-light and scientific imaging purposes, especially astrophotography. What’s been slowly shrinking over the years is the how much better CCDs are than CMOS.
CCD & CMOS SENSORS — AMATEUR ASTROPHOTOGRAPHY
- https://www.amateurastrophotography.com/ccd-cmos-sensors
- The area on a CCD (Charge Coupled Device) sensor is divided into pixels using a series of channel stops and gates. While the sensor is exposing, photons that fall on a pixel are converted into electrons and stored as charge packets. To readout the sensor after the exposure, we ‘clock’ the gates that form the pixels.

- Our calculator, at typical seeing of 2-4”, uses the Nyquist formula of 1/2 and the 1/3 to stop stars becoming square so the optimal range is between 0.67” and 2”. (0.67 = 2 / 3, 2 = 4 / 2). In summary, we are using Nyquist as a starting point, with a slight tweak, because we are typically sampling very small, circular, stars.
