The Strange Case of BL Lacertae

Serendipity has always been part of the process of discovery. Facts are collected. Perhaps they sit in cabinets and drawers for years, even decades, before someone takes the time to study them thoroughly. And perhaps something unusual is discovered. Even discovering and analyzing a point of light can bring surprises. In this case, it happens to be a ho-hum variable star.

A report by
The temperature was warm all night. Clouds covered over part of the sky to the north and threatened to invade the rest, but stayed away from the southern sky. Thanks to a poor attempt at alignment and computer initialization, both tracking and slewing were off by a considerable degree, affecting how well the computer/mount combination could center objects. Also, it didn’t help that I was picking targets in widely scattered portions of the sky. There was some light haze, and a thin crescent moon, but nothing too serious. So around 7:20PM I started setting up my 10-inch aperture f/4.5 Newtonian and Orion G3 camera for a night of deep sky objects. Since this is the only way to actually see more than a faint fuzzy patch of light, I dedicated myself to those rather than give views of the Moon and planets. People of all ages appreciated and liked my efforts, and had many good questions about just about everything. But the crowd this night seemed to be less than usual, especially for the last weekend of summer. Perhaps a large attendance at the Greek theater, perhaps many people left town?

Well, after more than six months, I finally got a chance to do some astronomy on July the 3rd. What a drought !
Oh well . . .
Once again, I was thankful for the laptop-controlled mount which made it possible to place the telescope within a half a degree of any object. The camera allowed me to see 9th mag stars to confirm where the telescope was pointing. This greatly speeds up finding objects under urban conditions where even finders are of limited use.
All photos were taken using an Orion 10-inch f/4.5 Newtonian and an Orion G3 color CCD camera.
