- can make a permanent record of an astronomical image and have much longer integration times than the eye, but they are extremely inefficient, retaining only very less of the light that falls on them. CCDs \textbf {CCDs} CCDs. retain major amount of the incident light and provide more accurate measurements of brightness than photographic plates.

- There are several advantages to using CCD sensors versus standard film: The sensor is very sensitive to light and is comparable to standard film with 1600 ISO [2] Greater range of brightness over film usually referred to as grayscale; Linear response – twice the exposure equals twice the light gathering capacity

- The end result is that the astronomical CCDs are more flexible and have less noise than your digital camera. The downside is that CMOS devices in digital cameras are much faster than CCDs. The other important difference is that astronomical CCDs are typically used upside down.

- The inventors of the technology, George E. Smith and Willard Boyle determined that because of the CCD’s light sensitivity that it would help cameras to capture more clear images because the more light that is collected, the more precise and clear the image will be.

- 4.1 Advantages and disadvantages of CCDs. The principal advantages of CCDs are their sensitivity, dynamic range and linearity. The sensitivity, or quantum efficiency, is simply the fraction of photons incident on the chip which are detected. It is common for CCDs to achieve a quantum efficiency of about 80%.

- A telescope with focal ratio f/10 and diameter D = 0.5 m has a CCD detector placed at its focal plane. The CCD chip has dimensions 3 × 3 cm2 . Determine the size of the field of view that can be imaged on the CCD detector in units of arcminutes × arcminutes, and state whether or not an image of the full moon can be captured.

- Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications. Electronic cameras based on CCD technology are used in applications from home video to medical imaging to astronomy. CCD cameras offer several advantages over film cameras: They can be connected directly to a computer, can be highly …

- Astronomers today have much more efficient electronic detectors to record astronomical images. Most often, these are charge-coupled devices (CCDs), which are similar to the detectors used in video camcorders or in digital cameras (like the one more and more students have on their cell phones) (see Figure 6.14). In a CCD, photons of radiation hitting any part of the …
Advantages of film over CCD/TTL astrophotography - Film ...

- I see no advantages at all of film over CCD or Digital astrophotography. Its faster, easyer don't need a darkroom and all those trays and chemicls, films that you have to buy and store plus they go bad if you don't use them. Ok I know you have to have a computer and know how to use it, there are always trade off.
