Ritchie X-11Y Navigation 2-Inch Dial Sport Kayak Compass (Yellow)

It is made in the USA. It is a high quality product and not small. Although it is primarily designed for boating I use it to align my telescope using magnetic north. When I place the compass over the optical tube, the rubber base prevents slip and fall. The rubber line and v-notch improve accuracy. It is very convenient to use this type of compass on a high telescope rather than military-type compasses which require looking from upside down. This compass does not interfere with metal. The neck lanyard helps to fix it on the telescope. I did not try the light sticks yet because the nice color of compass provides enough contrast to find direction.
