oil for Byers gear?

Posted By john lawson

My 12" telescope with a 12" Byers gear has been sitting outside for years and I have just cleaned it up. I put a light oil on the worm and the scope kind of stick slips in the normal direction (but not the other). Should these gears (bronze worm and aluminum wheel) be run dry, light oil or heavy grease? Thanks for any ideas.

orion autoguider and CI700 mount

Posted By john lawson

Has anyone made the Orion autoguider work with the Celestron CI700 mount?
If so, How?

Good choice?

I've just started to use the Pentax k20d for astrophotography and i'm
pretty impressed. No amp glow that I can see and low noise. I don't
think that you want to shoot at 1600 speed anyway. The only thing I
don't like is that you can't turn off the dark frame subtraction in the
present firmware.
