Images are recorded in structures and devices that can perceive images, and can store them
in a form suitable for later viewing or for delivery to some other location.
In reference to telescope images, there's one device that at one time was the only one ever used.
But as time went on, its use steadily decreased, until now, it's very seldom used for professional
work. That device is the eye and all the peripherals and other components in the system of which
it's a part. The system can perceive images, but only in visible light. The form in which they're stored
is in brain memory, which only works for one observer, and the image can't be delivered to others.
If the eye isn't being used, then we tend to call any other system a 'camera'. It's not quite right to say
that they all work in the same way, but they all do share the same 'high level' principle: Some other
sensing surface, other than the retina of the eye, is placed where the telescope forms the image.
For visible light or wavelengths close to it, the sensor may be a piece of photo film or a digital device
such as a CCD, sensitive to the band of wavelengths of interest. (The telescope gathers and focuses
a lot more than just the visible wavelengths, on both ends of that range.)
Film captures the image in the old familiar way, which can be stored, printed in books, or even
digitized later.
A digital device delivers its image directly as digital data, ready to store just as any other information
is stored in digital form ... on tape, in solid state memory, on a server or on a DVD etc., and it can be
delivered to other astronomers by email, by radio from the Hubble scope, on a flash drive, on a
website, or on the astronomer's Facebook page.

Telescopes
Telescopes are used by astronomers to collect light from celestial objects such as stars, planets, and galaxies. They enable astronomers to study these objects in detail, revealing information about their properties, composition, and motion. Telescopes can also help astronomers in detecting and studying phenomena like supernovae, black holes, and exoplanets.
Telescopes are commonly used by astronomers to observe objects in space such as planets, stars, and galaxies. Microscopes are not typically used by astronomers as they are designed for studying very small objects on Earth, such as cells and microbes.
Astronomers typically look through telescopes at the stars to study celestial objects such as planets, stars, galaxies, and other phenomena in the universe. They use telescopes to gather data and make observations that help expand our knowledge of the cosmos.

The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.
TELESCOPES
Astronomers wanted to put a telescope into space to avoid the distortion caused by Earth's atmosphere, which can affect the quality of images taken by ground-based telescopes. By placing a telescope in space, astronomers can achieve sharper and clearer images of celestial objects.
Astronomers use instruments such as spectrometers to analyze starlight and determine a star's chemical composition, temperature, and motion. Telescopes are used to observe stars and capture images at different wavelengths. Interferometers combine signals from multiple telescopes to create high-resolution images of stars and star systems.

Astronomers have used telescopes and charge coupled devices.
Yes, both of them. And they also use reflecting telescopes.
Very little astronomy is still done by physically looking through telescopes, so astronomers can basically work any hours they want. The really large telescopes are quite expensive and tend to be shared (and located in remote, desolate places). Most astronomers rely on dedicated on-site staff at the scope who collect images or data for the astronomers to analyze later.
