My Telescope and the one used to capture all these images. The Stella Cam Ex is mounted prime focus usually through the 2" diagonal. Normally it is not recommended to image through more glass (i.e. the diagonal), but I use one to retain all of my scope's swing through so I can image even at the zenith.This scope is operated completely by remote control from the computer room inside my house. An ETX-90 is mounted on top as a guider scope.
