Laying the Groundwork for the LAAS - Amateur Astronomers Past – Part 2
(Unless otherwise noted, much of the material presented here and in Episode 4 is based on an article by Dr. Mars F. Baumgardt, titled “Amateurs and Telescopes of Early Southern California.” It was published in the March 1940 Griffith Observer magazine, Vol. 4, No. 3, pp. 26-38, and is used with permission.)
Let’s continue where we left off in Episode 4 and go back to the 19th and early 20th centuries to learn about other early Los Angeles amateur astronomers. Many of them were the movers and shakers of Los Angeles, did much to popularize the science of astronomy and contributed a great deal to the growth and development of the city, the region and the state.

My wife and I were looking through an antique shop in Carlsbad California about ten years ago. I wasn’t looking for anything specific, but there are always “targets of opportunity” that could turn up. I was looking at some watches in a glass case when I felt a tap on my shoulder. My wife said, “You really need to come and look at this.” We went down an isle to a display cabinet upon which sat an old black box containing a number of glass lantern slides. I was stunned by what I saw in the box. It contained images of early 20th century telescopes along with images of images of large meteorites, photos of comets, photos of star fields, deep sky nebulae and many other things. It was obvious that she had found some sort of archive of old presentation slides about early astronomy in Southern California, made for some at present unidentified, organization. Many of the slides had hand written notes on them with names like G. W. Ritchey and E. E. Barnard. The antique shop was selling the slides individually, and some of them had already been sold. I wasn’t sure what I would do with this collection of slides but I couldn’t let it be sold off in pieces, so I bought the whole set of slides along with the black storage case.
Urban Imaging - One Clear September Night

On September 28th 2013 7:30pm, I started an observing run from the back of my townhouse, although I was hampered not only by bright urban lights, but by the lights from my townhouse, as you can painfully see at left . . .
I only planned to image Nova Del 2013 and see how bright it was(n’t), but in the process I got quite a few images, while learning to operate the equipment together. As Clyde Tombaugh noted in his excellent book “Out of the Darkness”, every piece of equipment has its quirks and idiosyncrasies, which needs to be recognized and worked around.
