This section of the Astroimaging website will examine accessories for the new Celestron Nexstar 6 SE. When designing an open measured sky view for local environments, a manual non-electronic compass is a very important accessory. The compass chosen serves telescopes, the marine industry, Boy Scouts, campers and the professional military.
The Eyeskey Optics Company model EK4076 handheld compass is of compact size and lightweight, easy to handle and carry. For night use, luminous dial and luminous magnet arrow, rotary 50mm dial with 360° scale. Accuracy is +- 0.5 degree. Made of high strength engineering metal, glass, and covered by enamel paint, which is capable of working under extreme weather conditions. The compass has a reading lens, aiming line, cover, graduated metric and imperial scales, cover, distance measuring notches, inclinometer, hinged, glass viewing portal, level bubble, threaded for tripod, wind rose, central support, 360-degree pivoting dial, reading adjustable eyepiece, north line with north arrow, metal hanging/holding ring, and case. Convex lens makes reading dial scale more clear. It has a lengthened proportion scale straightedge, and the cover can be flipped up and down 180-degrees to double the measuring range.

The astronomical compass was used to survey and determine the directions and dimensions of the open sky view from the observatory deck and is useful for the manual location of the Moon and planets from the directions of various environmental obstructions and to develop a mercator projection for the availability of clear viewing areas for future observations and studies. It can provide detailed and accurate data, determine the positioning of rising and setting of celestial objects, monitor times version cardinal directions, but only when not in the vicinity of cell phones, magnetic devices, magnetized metal, and other electronics.
The compass updates the Celestron Nexstar 6 SE telescope leveler and can provide a fast survey of the celestial night sky before observing. With this compass, directions will be known even if obscured by tall skyscrapers, mountains and other obstructions.
