Hi, my name is Don Goldman
and I live in Orangevale, California - a northeastern suburb of
Sacramento. I have a technical background with a Ph.D. in
near-infrared spectrsocopy. I am fortunate in founding a company,
Optical Solutions, to apply this background in building spectroscopic
equipment for chemical analysis for industry.
As a scientist, I have always been interested in astronomy. However,
I am relatively new to astronomical imaging. In fact, I purchased a
Meade LX-90 in February, 2001 primarily for visual use. In
June of 2001, I was fortunate to attend a lecture on CCD imaging at
the Sacramento Valley Astronomical Society. The point of this
presentation was to show how much detail can actually be obtained
with modern CCD cameras, even from light-polluted city skies. I knew
that this is what I wanted to do. It seemed like a great mix of
technology and art. So, I decided to purchase an SBIG ST-7E
CCD camera in July, 2001 along with an equatorial wedge for polar
alignment for the LX-90.
After using the camera for awhile, I became restless
with the small array size and upgraded my camera in April, 2002 to a a
Finger Lake Instruments MaxCam CM10ME CCD with large Kodak KAF-3200 array
along with a new mount, C-11, Borg guide-scope and SBIG STV auto-guider.
In November, 2004 I replaced this equipment with my current system -- a
12.5" RCOS Ritchey- Cretien open truss telescope,
Software Bisque's Paramount ME MKS4000 mount and an SBIG ST-10XME
I plan on getting involved with spectroscopy. I have modified a 15 mm
super Plossl eyepiece with a fiber optic connector to connect the C11
with my diode array spectrometer.
