Skies to Stars: Andromeda
By Ed Downs
It was another night at the Astronomy Club of Tulsa’s observatory, just southwest of Mounds, Okla. Yes, that is in the middle of nowhere, just right for dark night observing. It was also a visitor night, with a group of kids from a scout group and many adult visitors planning to join our group of astronomy nerds as we pointed our telescopes starward. With pleasant temperatures, it looked like a great observing evening, so of course, Oklahoma weather decided not to cooperate. Altostratus and cruciform clouds covered about two thirds of the sky, but a group of diehards headed out to do what we could to entertain and educate guests.
Our local expert and guru, John Land, conducted a terrific planetarium show, using what little of the sky could be seen by using a laser pointer, all the while promoting safe use of laser pointing devices, but trying to find a good target for beginners to view proved difficult. This writer was asked to see if I could find M 31 with my 12-inch Orion reflector, sometimes called a “light bucket” due to its ability to suck in even dim objects. Sure enough, M 31 was located, and folks were invited to view this wonder of the skies. We then realized the “M 31” meant absolutely nothing to the newcomers, and finally announced, “Who wants to take a look at the Andromeda Galaxy?”

The Christmas Star
By Ed Downs
The holiday season offers a huge number of both aviation and astronomical topics to write about. From the aviation standpoint, gift giving is made easy. Pilots will love anything that has to do with their flying activities or cherished flying machine. We are an easy “gift buy” group. Astronomy also has a firm connection with the Christmas season, with the Star of Bethlehem (the Christmas star) playing a major role in virtually every aspect of holiday decorations, lore and tradition. The biblical reference in Mathew 2:2 begins our tradition of “the Star in the East” and the holy journey of the three Magi, referred to as “The Three Kings” in late medieval times. It would be hard to imagine the Christmas tradition without this celestial miracle. A quick search in this writer’s biblical concordance comes up with no less than 10 references to the stars. And, it must be remembered that many biblical historians believe the Magi were astrologers, skilled in many arts and sciences, having familiarity with the prophecies of Daniel. While today astrology is considered a completely different subject than astronomy, they were once one and the same, and perhaps the oldest of all scientific understandings by ancient civilizations. Indeed, the stars are an integral part of the holiday season.
