The photos aren't all that great but I wanted to post about them anyway. It's been cloudy the last week and I'm going through astronomy withdrawal.

Re-greasing a Celestron CG-5 mount Posted by Michael Harrison

Comments (0) Trackbacks (0) Re-greasing a Celestron CG-5 mountI recently bought a used Celestron CG-5 mount and decided that after verifying basic operation, the next thing to do was to take it apart and do some basic maintenance. It's well known that the Celestron mounts made overseas need some rework to get full performance out of them. They frequently contain "lube" that is more like glue, the gears need polishing to remove burrs and many of the plastic rings look they've been cut from milk bottles.

How many CCTV cameras can you count? You're worried about what kind of privacy people voluntary give up through sites like Facebook when you've got all those eyes watching you that you have no control over? Your boat has left the dock. A long time ago. If you want to fight against privacy loss, fight against those cameras.

Comments (0) Trackbacks (0) 400 years of Jupiter's moonsI forgot to post about this yesterday, which was the 400th anniversay of the discovery by Galileo of Jupiter's moons Europa, Callisto and Io. Yeah Galileo! Go out and look at Jupiter tonight through at least some binoculars. You'll see a larger bright dot with smaller dots nearby. Today the average person has much better optics than Galileo had. Go look! Technorati : astronomy, galileo, jupiter |
