Meade Magellan I Digital Setting Circles for 6" to 16" Meade Starfinder Dobs. Included are 4000-step encoders for the Starfinder mount (alt-az), Magellan computer, installation and owners guides, a fresh 9V battery, and mounting hardware.
I was able to locate Uranus and Neptune at 220x for the first time with this system. The key to proper alignment is defocusing a star at high power. This out-of-focus disc is easy to center against the field stop of the eyepiece. Each time the unit is aligned it gives a number (about 90-110) which indicates the merit of alignment. With this method I can get the perfect value of 100 consistently. This precise alignment can put the object of interest in my 12mm Nagler (0.8 deg field) every time, and even in my Pentax 5.2mm XL (0.3 deg).
I am building a new Dob mount and tube for my mirror and decided to sell the encoders and computer as a set, since the encoders are designed for the Starfinder mounts.
