Biography
I am a
Physicist, retired from
Siemens Medical Solutions where I was Staff Scientist. I have drifted
away from science a bit in my imaging pursuits as I am now content to
merely produce pretty pictures rather than engaging in astrometry and
photometry.
I owe my progress in amateur astronomy to
my two mentors. Jack Schmidling patiently taught me all I know about image
acquisition and processing. Doc Clay Sherrod was my cybermentor, helping
me to understand the mysteries of the skies and the workings of my
scopes. I owe them a tremendous debt and I endeavor to repay it by
serving as a cybermentor to budding imagers on various astronomy groups on
the Internet.
Areas of interest
I enjoy imaging comets because they
are a dynamic target, fast moving and always changing.
Of late I’ve
specialized in H-a imaging because it levels the playing field when it
comes to light pollution. My H-a imagery is just as good from my 4.0 VLM
site as it would be from a truly
dark site. Such is the advantage of
narrow-band imaging.
Observing site
The
Igloo observatory is so named because when I first erected it, neighbors
commented on the “ igloo” in my back yard. It is located on a residential
airpark in Hampshire, IL. It is a ten-foot ProDome. I am about 45 miles
east of Chicago, with considerable light pollution. The VLM varies from
3.0 to the east to as good as 4.5 at the zenith on exceptional nights.
Unfortunately my Midwest seeing is seldom better than Pickering 4,
limiting me to shorter focal lengths.
