Description
Cassens & Plath Star Astigmatizing Lens is an optical aid developed for observing navigational stars with a sextant. The lens makes constellations easier to identify by transforming point-shaped stars into small lines in the field of view.
In astronomical navigation, stars can be difficult to observe because they appear as small points of light. An astigmatizing lens changes how the star is perceived in the optics, making it easier for the navigator to identify and adjust the observation towards the horizon.
This accessory is often used for star sightings during celestial navigation, especially during night navigation where precise identification of stars is crucial.
The Cassens & Plath Star Astigmatizing Lens can be used with several Cassens & Plath sextants and is a useful accessory for navigators who want more precise observations of stars.
The black finish gives a discreet and stylish look that goes well with the sextant’s optical equipment.
