Unlike other competing models, you have:
--16 character red LED (not LCD), so works in cold,
--rich object descriptions (name, type, appearance, size, mag),
--do not have to enter date (or wait for planet calcs each time),
--accuracy feedback on (re)alignments,
--access to alignment stars during use.
Accurate. No need to level--for alt-azimuth mounts, point scope vertically, align on two stars. Realign works well.
Works with dobsonian and equatorial mounts. Need to buy the appropriate installation kit for your mount elsewhere (encoders, cable, and brackets).
