The Mintron used with a NexStar N11GPS and a Hyperstar

lens assembly (at f/2.1)

One of the most amazing results using the Mintron at the N11GPS can be achieved when

using this camera in conjunction with the Hyperstar lens assembly. This wide-field setup is

especially suited for a remote observing setup. You can find an article on how to build the

necessary adapter on my homepage. Here are some pictures of the complete assembly:
