No , there just very good digital setting circles so to speak.
They give you a read out of what your scope is pointing at.
I was contemplating getting them at one stage but decided to fork out some more $s, build a large fork mount and go the Go-To route in the form of Mel Bartels System.
It is designed to work with a Dob or EQ scope.
All you need is his system a cheapy CPU to run it on (picked up an old p3 in the papers for $50) so it can interface with a planetarium program (although it will run with out in basic drive mode) and some modification to you existing Dob mount in the form of some large ply discs ect .
It is going to be more expensive than the A.N. but gives you one hell of a tracking platform in either ALT AZ or EQ modes .
Have you checked it out Mike?
He has designed it to be the most affordable system for the amature with out comprimising functions. It just depends on how handy you are . There is a Yahoo Forum web site for questions and info from others.
Mine should be here in the next few weeks.
