Eye Pieces: 22mm Panoptic, 9mm Nagler, 25mm Plossl, 32mm Plossl<br />
Weather: Warm, Humid, Few Passing Clouds, Breezy, Bright patio lights from neighbors<br />
Moon: 1st Quarter</p>
<p>Alignment Stars: <a href="http://en.wikipedia.org/wiki/Spica">Spica</a> and Arcturus<br />
Calibration Stars: Vega and <a href="http://en.wikipedia.org/wiki/Antares">Antares</a></p>
<p>Did not really plan out my session.  Even though I had a nap earlier in the day I was still kind of tired from being out in the morning, but I did not want to let the clear sky go to waste.</p>
<p><a href="http://www.suffolksky.com/wp-content/uploads/2010/06/log_book.jpg"><img src="http://www.suffolksky.com/wp-content/uploads/2010/06/log_book-150x150.jpg" alt="Observation Log" title="log_book" width="150" height="150" class="alignright size-thumbnail wp-image-728" /></a>From my observing notes:</p>
<p><a href="http://en.wikipedia.org/wiki/Messier_13">Messier 13 &#8211; The Great Cluster in Hercules</a> &#8211; M13 is a globular cluster located in the constellation Hercules, I had to work a bit to get good focus using the 9mm in the C6.  Once I was able to get focus it was very easy to resolve the individual stars outside of the clusters center.  Also, able to resolve well with the 22mm.  Focus was easier to obtain with the 22mm.  While focusing on M13 with the 9mm Nagler I did notice a <a href="http://www.astronomiainumbria.org/advanced_internet_files/meccanica/easyweb.easynet.co.uk/_chrish/lx_flop.htm">&#8220;mirror shift&#8221;</a>, this is the first time I have experienced this in any of my scopes (not saying it has not happened before, this is just the first time I have noticed it).</p>
<p>I also observed <a href="http://en.wikipedia.org/wiki/Messier_5">M5</a>, <a href="http://en.wikipedia.org/wiki/Messier_10">M10</a>, <a href="http://en.wikipedia.org/wiki/Messier_92">M92</a>, and <a href="http://en.wikipedia.org/wiki/Messier_12">M12</a>.  Messier 12 was the hardest of these to resolve.</p>
<p><a href="http://www.suffolksky.com/wp-content/uploads/2010/06/saturn_sketch_06192010.jpg"><img src="http://www.suffolksky.com/wp-content/uploads/2010/06/saturn_sketch_06192010-150x150.jpg" alt="Saturn Moon Location Sketch" title="saturn_sketch_06192010" width="150" height="150" class="alignright size-thumbnail wp-image-752" /></a>Saturn looked very nice with the 9mm.  The shadow of the planet&#8217;s rings were easily seen on the planet&#8217;s surface.  The rings are still nearly edge on so there was no real detail to be seen.  Three of Saturn&#8217;s moons were easily visible.  I looked up the planet in <a href="http://www.stellarium.org/">Stellarium</a> to figure out which moons we were seeing and they were <a href="http://en.wikipedia.org/wiki/Rhea_%28moon%29">Rhea</a>, <a href="http://en.wikipedia.org/wiki/Tethys_%28moon%29">Tethys</a>, and <a href="http://en.wikipedia.org/wiki/Titan_%28moon%29">Titan</a>.  I am not very good a sketching but I did draw a small sketch of the moons locations so I could look it up.</p>
<p>The kids came out for a bit to look at Saturn , Mars, and the Moon.  My son Johnathan stay out with me for most of the time I was out, which was cool since he is generally not into it.  </p>
<p>We tried to look at M81 and M82 but both of these appeared as just smudges.  M81 had a bright center but no detail and M82 showed no detail, just a smudge of faint light.  I am not sure if it was because of the amount of light pollution or if these targets are just better suited for the 8&#8243; scope.  I have observed both of these with good detail in the 8&#8243;.</p>
<p>Around 11:30 we were over the heat, humidity, and mosquitoes so we called it a night.</p>
