I am pondering a DM-4 versus a Giro-2 for a 4.5" refractor.
The DM-4 with encoders will absolutely be orthogonal for DSC's.
OTOH the Giro-2 allows adding counterweights, allowing for a larger scope
down the line.
(I've heard a rumor that the DM may be looking at adding counterweight
support.)
The Giro is 1/2 the cost.
Decisions, decisions.
