Filters mounting procedure

This paragraph describes the complete procedure to be followed to mount the filters on the
integrated filter-wheel. The wheel uses standard 1.25" mounted filters or 31mm unmounted
filters.
The AST492 is equipped with a 7 positions filter wheel. Position number 1 is referenced by a
small white arrow near the hole, which points to the direction where position 2 is located.
