More on Aquarius' position and stars

Event Date: July 29th
Time: 11:00 PM


Brief

Yestersday, I showed Aquarius with its stick figure. Although most of its stars are too dim to see easily, they trace out the Water Bearer quite well for if we look carefully at it.  First, the image I will include is the same as yesterday's first one...sortof...minus labeling and the stick figure!  The azimuth is identical to yesterday's looking east-southeast.  If you see the "arrow" of Capricornus to its southwest (right), Aquarius' extended legs extended, his torso, and then a lopsided "loop" showing his "water bowl". 
**This is one of the rare times that I will ever show an image with no labeling or stick figures, yet it should help you recognize this part of the sky when dark enough to see low.**



Detailed

   The second image is a near-duplicate of yesterday's of Aquarius and M2, including the figure and star names.  Did you easily identify the Aquarius stars without the aid of the stick figure??

   I normally do not duplicate images so soon for journals on consecutive dates, with the exception of showing how our revolution around the Sun shows a slightly change in altitude; that can be noticed today also if we look closely.  This time, I also labeled a few more stars that could help identify it if you looked for those before anything else.  Good luck seeing it in the night sky, where there are no stick figures, hence putting in image one, once again. 
Use the images of Aquarius' stick figure and labels when outside viewing, or one of today's popular "apps" on mobile devices if you point it towards Aquarius: such can help enhance viewing dim astronomy constellations and as a reminder of where they are.  However, try to also get to know your sky well by studying it aid-free.  When you go back later to your software or app, see how easily you can identify dim stars as well as brighter ones!  Many of the labeled above are 3rd or 4th magnitude.  If you don't see the most eastern ones at first, wait until the entire constellation gets higher out of atmospheric pollution.
