This sky-watcher finder has an erect and reversed image. It is mounted on a finder bracket suitable for Sky-Watcher standard finder shoes. The image is identical to that seen through a refractor or Maksutov Cassegrain telescope fitted with a star diagonal. The 90° view makes it much more convenient to use than a conventional, straight viewfinder.
