16-mm/2.8 Fish-eye
This is an image obtained while observing on Crimean Observatory.
I set up my Edixa Prismaflex TTL on a tripod outside the dome
at Zeiss 50" and opened the camera for several hours. The
2.6 m Shain reflector is visible at center. The time exposure
of about 5 hours duration showing circumpolar stars. The dome
can be seen to blur slightly due to their motion during the exposure.
