SH2-114, the Flying Dragon Nebula, is a filamentous hydrogen emission nebula in the constellation Cygnus. This is a very dim nebula -- the dragon was not visible in any of the individual images; only after I combined 61 5-min exposures (a total of 5 hr 5 min of data) was this image achieved.

The dragon is estimated to be about 3,850 light-years, so I captured photons that were emitted at about the time that the earliest known Egyptian medical text, a papyrus addressing fertility, pregnancy, and gynecological health, was written.

Composite of the lunar eclipse, Aug 27-28, 2006. Images start about 15% into the partial phase, then about 75%, then close to peak, then 75%, then 15%.

Wolf-Rayet 134 is a large, bright star in the constellation Cygnus. Although it is not especially visible, the bubble of oxygen gas excited into a blue glow by the intense radiation from this star is the most salient feature of this image. Only one side of the bubble is obvious in my 3+ - hour exposure; a longer exposure could reveal the much dimmer remainder.

WR 134 is about 5,700 light-years from us. The photons from this bubble set out when horses were first domesticated in what is not Kazakhstan, and when the first Neolithic settlers appeared on the Greek island of Santorini.

Also present in this image are two open star clusters (NGC 6883 and 6871) but they are not distinct against the dense background of Milky Way stars.

Melotte 15 is a group of young, hot stars at the center of IC 1805, the Heart Nebula, in the constellation Cassiopeia. With my long focal length telescope this group dominates the view, surrounded by the much larger heart-shaped shell of hydrogen that is glowing due to the energy of these stars.

Melotte 15 is 7,500 light-years from our Sun, so I captured photons that left these stars at the time of the earliest archaeological evidence of cheese-making (in Poland), and of the earliest copper smelting (in Russia).

Great Escape Stage Company's Gala "Miscast Broadway" -- see it Saturday Aug 15 at 3:00 and 8:00 PM. What songs will they perform? You'll have to attend to find out! (...But I bet you can easily guess the show that gave us one of the songs.)
