-COMPTEL was the MeV Compton gamma-ray telescope on board of the NASA Compton Gamma-Ray observatory (CGRO). This was the second of NASA's Great Observatories, ​with17 ​tons the heaviest scientific payload ever flown at the time of its launch on April 5, 1991 aboard the space shuttle Atlantis. Compton was re-entered into the Earth'​s atmosphere on June 4, 2000.+COMPTEL was the MeV Compton gamma-ray telescope on board of the NASA Compton Gamma-Ray observatory (CGRO).

-COMPTEL was an imaging Compton telescope that utilizes the Compton effect and two layers of gamma-ray detectors to reconstruct an image of gamma-ray sources in the energy range 0.75 to 30 MeV. It had a field of view of approximately 1 sterradian, an angular resolution of the order of 1 degree and a spectral resolution of 6-10 %. Gamma rays from active galaxies, radioactive supernova remnants, compact objects, and diffuse gamma rays from the interstellar medium were studied with this instrument.+COMPTEL was an imaging Compton telescope that utilizes the Compton effect and two layers of gamma-ray detectors to reconstruct an image of gamma-ray sources in the energy range 0.75 to 30 MeV.
