The Kryoneri Observatory was established in 1972 and in 1975 its first telescope was installed, a 123 centimetres (48 in) Cassegrain reflector manufactured by Grubb Parsons, a British company based in Newcastle.

After the Second World War, Korgialenios' bequest had suffered considerable mutilation and the subsequent distress of the country led Stavros Plakidis, then director of the Οbservatory, to decide that such a purchase could not be made.

[3] On the back of the Prime Focus Instrument there are two fast-frame sCMOS Andor Zyla 5.5 cameras offering the ability to record a target simultaneously in two different wavelength bands.

[7] Next to this building is one of the stations of the Very Wide Field of View network, which is equipped with a sensor for detecting objects in Low Earth Orbit using Optical Triangulation.

The station consists of a sensor developed by Cilium Engineering and it is desined to detect objects in Low Earth Orbit using the Optical Triangulation method.

[8] The Manchester-Athens Wide-Field (Narrow-Band) Camera (WAWFC) is a Deep Sky Survey of the extensive line emission regions at high galactic latitudes.

[8] It is a joint project of the National Observatory of Athens and the Jodrell Bank Centre for Astrophysics of the Manchester University that aims to conduct a large-area sky survey with the aid of a customized camera and narrow-band filters properly designed for studying extended interstellar medium (ISM) structures in the optical emission lines of Ηα, [O III], and Hβ.

[8] As part of the program, the Korgialenio telescope detected lunar impact flashes during the Perseids meteor shower in 2023, using the instruments developed for the NELIOTA project.

The plan is to fire a high-powered laser to the Psyche spacecraft, which will then send back a response to the Aristarchos Telescope in the nearby Chelmos Observatory.
