Digital Compass POLE FINDER NS-10 GPS

Digital Compass for Equatorial Mount POLE FINDER NS-10 GPS - Smoothly align the polar axis even in dark places where the North Star is not visible.

This is an electronic compass that supports the alignment of the polar axis of a portable equatorial mount during celestial observation and photography. It has a built-in 9-axis sensor, allowing for easy and quick setting of the polar axis (toward the North Star) at the specified latitude. By using the included GPS module, it can automatically set the magnetic declination and latitude information for the location of use. (The automatically set magnetic declination value is only valid within Japan; manual setting is required overseas.) It is suitable for relatively short exposure astrophotography and constellation photography. For long exposure or telephoto lens photography, precise adjustments using a polar alignment telescope or similar equipment are necessary. The magnetic declination values are based on the information published by the Geospatial Information Authority of Japan in 2020.
