Astronomical Observing at Fishcreek Observing Site

Friday - 11/06/2009 at 7:00 PM

 

THIS EVENT WAS CANCELLED
despite near-perfect weather conditions.  Why?
 

1)  The field where we set up equipment was far too wet.

2)  An event occurred at the school tonight and the parking lot lights were left on.  They're brighter than the Sun on a cloudless July day.

These two conditions make observing impossible, sad to say.

Tonight, we have a 78% illuminated (waning gibbous) Moon rising at 8:31pm.  This phase is great for viewing detail in the craters and maria on or near the terminator - the line separating lunar night from day, a wealth of features can be seen.  Faint DSOs (Deep Space Objects) will be partially obscured due to the Moon, but Jupiter will be beautiful with all four of the Galilean moons lined up on the west side of the planet.  Take a look at the information for Jupiter, below.  We have the colorful double stars, open clusters made up of hundreds of stars, the globular clusters comprised of hundreds of thousands of stars, planetary nebula formed by dying stars, diffuse nebula and emission nebula where stars are being born.  Galaxies may not be visible this evening, except for M31 - the Andromeda Galaxy - our closest neighboring island universe.  Bring binoculars if you have a pair and we'll show you how to find the Andromeda Galaxy with them!  Also, we'll show you how to find the beautiful "Coat hanger" cluster which is best seen in binoculars.

We hope to see you here for a night under the stars - now in our fifteenth year!

On 11/6/2009 at 6:16:56pm the Moon will be 18.2 below the north-northeast horizon
but will look like this at very low power* in our telescopes when it clears the trees at 10:10 PM...



*
How do we change the "power" (magnification) of our telescopes?
Simple!  By changing the eyepiece to one of a longer or shorter focal length.
If the eyepiece is of shorter focal length, the "power" (magnification) is higher,
If he eyepiece is of longer focal length, the "power" (magnification) is lower.
By how much?  Here's the formula:

Magnification =F focal length of telescope objective lens (or mirror)
focal length of eyepiece being used      

Note: All graphics are correct-image representations.  A telescope will reverse this left-right and possibly invert up-down depending on type of equipment being used.
