Caeleste is pleased to announce that it has been officially accredited under the Crédit d’Impôt Recherche (CIR) by the French Ministry of Higher Education and Research.
Hera Spacecraft Captures Distant Asteroids with Caeleste’s Faintstar2 Sensor

On its way to the Didymos double asteroid system ESA spacecraft Hera has successfully captured images of distant asteroids (1126) Otero and (18805) Kellyday. This was done with the Asteroid Framing Camera (AFC) – a navigational and scientific instrument meant to guide the spacecraft during its approach to its mission target, next year.

Webinar: The Future of Detectors in Astronomy – Insights from Caeleste and ESO

FTG is a pixel concept that enables non-destructive readout in plain CMOS (CIS) pixels. By repeating the measurement multiple times, the accuracy of the photocharge readout improves with the square root of the number of repetitions. Figure 1 illustrates schematic cross section of a FTG pixel next to NFTG.
