The hen’s chest
Way up there in the eastern sky somewhere is a star named Sadr. I can barely make it out through all the light pollution, but I know it’s there, because my trusty telescope Stella dutifully bores a hole for me through the polluted atmosphere so I can peer into outer space. Even better, if I squeeze the incoming photons through a narrow-band hydrogen-alpha filter, I see less light from nearby streetlights and more of the illumination stars are sending my way.
Sadr resides in an interesting celestial neighborhood in our galaxy, the Milky Way. It is surrounded by clouds of nebulosity from the galaxy’s cosmic dust, making a more interesting picture. From Wikipedia (where else?) I learn
Gamma Cygni (γ Cyg, γ Cygni) [designates] a star in the northern constellation Cygnus, forming the intersection of an asterism of five stars called the Northern Cross. It has the traditional name Sadr… , which name comes from the Arabic word صدر şadr, “chest”, the same word which gave rise to the star Schedar (Alpha Cassiopeiae). In the catalogue of stars in the Calendarium of Al Achsasi al Mouakket, this star was designated Sadr al Dedjadjet, (صدرألدجاجة-şadr aldajaaja), which was translated into Latin as Pectus Gallinǣ, meaning the hen’s chest.
Now you know.
This photo represents a 30-minute total exposure. I plan to follow with similar exposures through Oxygen III and Sulfur II filters. The two additional shots will be combined with the hydrogen-alpha exposure to dazzle you with colors that the human eye probably would not see, even if Mr. Sadr was brighter in the sky. I will commission water color artist bro Tom to come up with an appropriate palette. For this he will earn his 15 minutes of fame, which has been a long time coming.
To continue the back story, I have been long convinced that the God of the heavens completed his building of the Universe some 14 billion years ago and has provided us with two instruction manuals; the Holy Bible and Nature itself. To quote a gent even older than I am, “The heavens declare the glory of God, and the sky above proclaims his handiwork” — Psalm. 19:1.
I believe it.
