Sky-Watcher 9x50 viewfinder with comfortable 90° view - upright and reversed image
This viewfinder has an upright and reversed image. It is mounted on a finder holder suitable for Sky-Watcher standard viewfinder shoes. The image is identical to that seen by a refractor or Maksutov Cassegrain telescope when equipped with a zenith mirror. Due to the 90° view, the use is much more comfortable than with a conventional, straightforward viewfinder.
