You can see an example of it by looking at Einstein's cross in a 18" or larger Dob/truss scope under really dark skies. Einsteins cross consists of a 15th mag galaxy PGC 69457 near Pegasus that is lensing a distant quasar. Once you locate the galaxy, the quasar is four distinct points measuring about 18 mag around the galaxy. We have seen this in a 24" truss scope from Cherry Springs PA. home of the Black Forest Star Party (plug plug...) Gravitational Lensing is not just for pro’s.

Take note as well of the weekly Carnival of Space, now in its 9th edition, this week edited on the Planetary Society’s weblog by the able Emily Lakdawalla. Here again the range is spacious, with musings on the atmospheres of extrasolar planets to the nano-minded Brian Wang’s thoughts on laser systems that could get us to Mars. If you only have time for one, don’t miss Pamela Gay’s take on gravitational lenses, a fine job on a tool of ever growing importance.
