Event Report:

Another successful night of stargazing at Fishcreek.
Excellent conditions allowed tremendous views of
many deep sky objects including the Milkyway and
Comet Garradd (C/2009 P1) in Delphinus at magnitude 8.3


We hope to see you for our next planned event on 8/26/2011

Click here for chart of Solar/Lunar/planet availability for tonight. 

Tonight, we'll be Moon free until it rises at 10:41pm.  The dim DSOs (Deep Space Objects) that we love to view, will be available until approximately 1:00am when the Moon will clear the trees to the east of the observing field.  Beautiful Saturn with its magnificent rings and moons, is almost gone for another several months.  The Earth's rotation of the Sun has now carried us far enough so that Saturn is nearly lost in the glare of the Sun.  Don't dispair, however...Jupiter is rising early enough now for us to see this king of the planets.  Colorful double stars and open clusters made up of hundreds of stars that will look beautiful; the globular clusters will be fantastic as will the planetary nebula formed by dying stars.  The diffuse nebula and emission nebula where stars are being born will be visible.  Galaxies will be available to us, but difficult unless the night is perfectly clear.

Click here for a list of DeepSky Objects that will be available to us this session.

How about the planets...which ones can we see tonight? 

    Sun is obviously unavailable to us, it will be night time after all. 
    Mercury is rising 10 minutes before sunrise and now totally lost in the glare of the rising sun.
    Venus is now rising 3 minutes after sunrise and, like Mercury, totally lost in the glare of the Sun.
    Earth is what you'll be standing on as you look up. 
    Mars is a late night object now, rising at 2:45am.
    Jupiter is a late night object rising at 11:10pm.
    Saturn is visible in the evening until it sets at 10:22pm.
    Uranus rises at 9:40pm.
    Neptune rises at 8:18pm.
 
  Pluto rises at 4:59pm, but so incredibly small and dim that we can't see a thing in our telescopes!  We can show you where it is.  OK, OK...if you want to try to see it, we'll try.  Don't expect to see anything, though!
    Moon is nearly at third quarter and rises at 10:41pm tonight.

Never EVER point your telescope at the Sun!!!  Instantaneous and permanent eye damage will result!!!
Very special equipment is required to provide an image like this...don't try this at home.

At 1:00am when it clears the trees to the east of the observing field, the Moon will look like this in our telescopes at low power*:


*
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.

On 8/19/2011 at 9:23:40pm Mars will be 23.9 below the north-northwest horizon

Question: Will Mars be "as big as a Full Moon on August 27!" ???
 Answer: ABSOLUTELY NOT!!!

Question: Will there be "Two Full Moons in the Sky!" ???
 Answer: ABSOLUTELY NOT!!!

Mars was the closest in recorded history on August 27, but that was only in 2003, not every year!
At that time, it appeared to be 1/75
th the apparent diameter of the Moon!  NOT the "same size as the Full Moon".
