Description

By both focal reducing and stopping down the Startravel 80/400 telescope, a 60/230 combination is obtained. Thanks to the use of the Fringe Killer filter, CA can be limited to reasonable level.

The main limitation of this setup is the small field without distortion, less than one degree.
