Quote:To make it possible for the RA circle to move with the clock rather than being fixed to the mount. The Plexiglas pointer also is fixed to the polar shaft.
I'm hoping you know the benefits of doing this way Dave!

Quote:Quote:I don't think the Meade Newtonians ever had driven RA circles eitherI think the RA circle on my 645 turns with the clock. It's loosely friction fit so that you can reset it.
Quote:the RA circle is on the RA casting and doesn't move except when you turn it manually
Quote:Its not the best situation observing from a giant slab of concrete heat sink but otherwise I have hardly any level lawn.
Quote:Your drive has the rare automatic RA circle kit installed we were just talking about earlier.
