StellarVue Refracting Telescope

Piggybacking on the RASA is a custom StellarVue refracting telescope, with aperture 80mm, f-ratio f/5.25, and focal length=420mm.  It has a field flattener and focal reducer.  The prism at the front has the same 7-degree wedge angle as on the RASA and the same dispersive glass type, but has a square cross section 75mm x 75mm.  It rides piggyback on the RASA, always pointing toward the same location in the night sky.

The ZWO ASI1600MM camera has a sensor with a 31mm diagonal length, giving a field of view of 4.2 degrees diagonal, similar to that of the RASA system.
The StellarVue and its ASI1600MM camera serve to confirm or reject detected laser pulse candidates identified by the RASA Schmidt system, albeit with lower signal-to-noise by a factor of 4.
