The AN, is THE best system that you will get for finding your way about the heavens.
And, to cap it all off, it is run/owned by THE nicest of guys, Gary. He is a member here, but possibly too modest to blow his own trumpet.
The AN interfaces with a set of encoders on either your dob mount, or even a german equatorial, and helps you pin-point where you are pointing.
Next time you are at a star party I am sure you will see many of them. I have one, and it is fantastic. many other forum members have them.
