POLARIS

Description

During fix star and planet observation the POLARIS shows its true strengths.

The unique clear-view-horizon-mirror combines all advantages of the full-view-mirror with those of the traditional split-view-mirror. In addition, it guarantees a wide field of vision and a precise view of the horizon even during poor visibility conditions. Yet another distinctive feature is the star-spreading glass (astigmatizing lens) which breaks a single point of light into a line, thus eliminating the need to swivel the sextant.

Furthermore, there are scales for a combined dip and index error adjustment on the drum screw. This index error adjustment on the sextant was developed by Bobby Schenk.

Indirect illumination on the arc as well as on the micrometer drum (vernier) allows for a glare-free reading at night.

Please note: The 6 x 30mm telescope as well as the artificial horizon do not fit together with the sextant in the Rough Case. Here we recommend the wooden case, in which an additional holder is attached.
