This second Weltblick Model 131 is owned by Holger Kramer. It is equipped with a Unihex and an electric motor. When he acquired it from a friend it was in bad shape, requiring cleaning, lens alignment, and work on the mount. The scope is being used quite frequently for astrophotography. Some of his photos are included.
