Telescopes are instruments of hope and faith. Hope that a better, clearer and brighter universe can be observed. Faith that we can bring these discoveries back to our small planet and create positive changes for all of it's inhabitants.

Quote:Dan - thanks! I feel lucky and very fortunate to have gotten this scope...and owe a big "thank you" to Stan Lopata and his wife Terry for making it possible for me to own it (we had a nice visit with them when we drove up to pick up the scope).Different topic - I can rotate the OTA within the rings, but it takes some effort to do so...is there anything I should check that might make the rotation easier?John
Quote:And a picture of the drive with the case off...note that the RA axis gear and the drive worm are hardly engaged, and that the adjustment bolts with springs that I've seen in every other Cave drive aren't present here...the three bolts have what look like two split collar washers, and a nut on the other side...with everything "tightened up". Any thoughts on that?

Quote:John - here's the "down the OTA" shot!
If I need to clean the mirrors while they're out (and I won't do it unless they're a lot dirtier than they look), what would you recommend as the best way to clean the primary?
