Astronomical Observing at Fishcreek - Friday 6/29/2007

This week, the Moon will be about as full as it can get, so there won't be much opportunity for viewing the deep-sky objects to fullest advantage.  However, viewing planets isn't affected by the brightness of the Moon and we have three beautiful planets from which to pick!  Saturn and its rings is just incredibly beautiful and will be within a degree of Venus which appears like a tiny crescent Moon in the telescopes.  Some of the telescopes will be able to see both planets in the same eyepiece field!  Jupiter's Great Red Spot should be visible as well as its four moons: Io, Europa, Ganymede and Callisto.  Double stars are another class of object unaffected by the brightness of the full Moon and there are plenty of those from which to choose.  We'll have a great night with plenty to look at despite the brightness of the full Moon.

We hope to see you here for a night under the stars - our twelfth year.
