Versatile nebular insect - eye Fabry - Perot spectrograph
Abstract
The design and performance of an insect-eye Fabry-Perot spectrograph used on a 249-cm Newtonian telescope, which can also be converted into a nebular filter camera, is presented. This device has several novel features, including a pressure-controlled optically contacted etalon and an image tube as a detector.
