Caption: To mark the 44th anniversary of the first man on the Moon, the astronomical group ¨ASTROTECNO¨, made a rocket festival in the town of Calimaya, State of Mexico. The Saturn V, owned by the engineer Rafael Lopez Velez, was the special guest of the event.
The rocket and its platform were accompanied by a midday Sun, with its majestic Halo.

Caption: Albireo, also known as Beta Cygni appears to the unaided eye to be a single star of magnitude 3 in the Constellation of Cygnus, but through a telescope, even low magnification views resolve it into a double star. The brighter Golden yellow star (actually itself a very close binary System) makes a striking colour contrast with its fainter blue companion star.
The Golden Star Albireo(component A at magnitude 3.3) & the Blue star(component B at magnitude 5.5) system are not a physically connected system, the Blue star is actually twice as far away as the Golden Yellow one, just happens that “line of sight” makes this a pair. Albireo is located about 430 light years from Earth!
Certainly Albireo is one of the Finest examples of a Colorful Double Star Pairing!
Separated by 35 seconds of arc, the two components provide one of the best contrasting double stars in the sky due to their different colors.
Often Albireo (aka Beta Cygni) is the first light target for many with new telescopes!
I captured this shot from my backyard in Dayton, Ohio last night on 07-25-2013, at the Prime focus of a 10” dia. telescope & Canon Rebel Xsi DSLR, ISO 400, 1 minute exposure unguided.
Here is some more information on Albireo written by my good friend Dr. Jim Kaler.

Caption: Here is the latest rendition of the Crab Nebula supernova remnant:

It is always very difficult to present objects like this that are so well-known in a way that still offers something (anything!) new. In this image I concentrated on enhancing the nebula with H-alpha data as well as maintaining the very fine blue/green filamentary structure *within* the nebula. This feature is generally overwhelmed when blending H-alpha data.
Additionally I went ahead and created an animation that blinks this image with an image taken in 1999 by ESO's VLT. You can see the video on Vimeo here:
Finally the creation of this image was recorded to become a tutorial on H-alpha blending available at the SkyCenter website.
