The ASA's are cool to be sure, but anyone who thinks you don't need to guide because the RA has minimal PE is deluded IMHO....I've seen stars drift several arc sec in DEC on many nights solely due seeing.
If you then accept guiding as a given, not matter how good the RA drive, then guiding *adaptively* is the next step....
