a Solar telescope is one, also a Coronagraph which is used to in a sense make an artificial eclipse in the observatory. The Coronagraph was invented in l93l by a French Astronomer. I saw two of them once in a museum in Philadelphia in the seventies, oddly they were in a temporary exhibit with weather instruments, ok, solar energy is part of weather, I am sure. They had telescopes with the necessary light-reduction filter ,opunted on shouder stocks rather like Mannlicher rifles, these were full-length shoulder stocks, the Coronagraph was the (barrel) I seemed to think they had a trigger group also, possiblky these had a camera attachment The astronomer"s name was Bernard Lyot prounounced (Leo) like the Lion constellation. Dop not confuse with chronograph which is a type of watch, Many do confuse the two, Corona meaning Crown, part of the Solar structure normally invisible except during an eclipse. Obvosy there are serious eye-safety concerns here requiring special light-attenuation to bring down the solar light to a safe level. I wish I had more information on this unusual instrument which was aimed directly at the sun with a shoulder stock.l
