The Dense Starfields between Deneb and Sadr in Cygnus

Object: Stars

Site: Front Yard

Seeing: 5 (Best I’ve seen in a while)

Transparency: Excellent

Type: Deep-Sky

Constellation: Cygnus

Magnification: 10x

FOV: 4.8 Degrees

Observing Time: 10:15pm – 10:35 pm

Notes: The rich star fields in the neck of Cygnus the Swan, between Deneb and Sadr.  At the beginning of my observing session I was looking for the “Keystone” in Hercules; didn’t find it, I’ll try again another night.  The Keystone is too large to fit inside a FOV of 4.8 Degrees, so I will not see it all in one field.  I then turned to the Summer Triangle and the respective constellations of the three brightest stars: Altair, in Aquila, Vega, in Lyra, and Deneb, in Cygnus.  The first star I observed was Vega in Lyra.  I tried to make out Lyra’s distinctive kite shape, as seen in the star charts, but I didn’t see it and was brought back to only seeing the epsilon lyrae star group, Vega, and delta-1 LYR in a distinctive triangle formation– see my “July 2nd, 2010” Posting for details.  I later found out that <again> Lyra the constellation is too large to fit inside my FOV, which was surprising since it looked relatively diminutive in the charts.  As a final destination for tonight, I marveled at the magnificent starfield in Cygnus, pictured above…I’m guessing a little over 100 stars were visible, which was quite a treat.  Seeing and Transparency were quite awesome too tonight.

Nice to see you’re still finding time to go outside. How are those finals coming?

Weather hasn’t been too kind over the last while, judging by the # of mosquito bites on my arm I’ve been outside no more than 4 times in the past month….. Care to recommend a second hobby? xD
