The passion of a life study ...

My latest license plates

I first began to look up at the sky when I was six years old. I would go outside in my non-light-polluted backyard in south-central Kansas, and just stare up, looking ... and wondering.

A few years later, on a trip to the Grand Canyon, my parents got me the Golden Guide to the Stars. That was just the beginning.

When I was in high school, I bought a Criterion 8" f/7.5 Newtonian on a German Equatorial Mount, and began in earnest to observe the sky in close detail.

I got fork-mount fever before succumbing to aperture fever. It went: Criterion Dynamax 8, Meade 2120/LX5 10", and culminated with the 12" LX200.

Lately I have acquired several small, special-purpose telescopes.

Now, I encourage my daughter as much as I possibly can.

Merry Christmas Lucia's telescope is a 4.5" 4501 Meade Newtonian reflector. She love's it.

Omega Centauri

Globular cluster Omega Centauri
Globular star clusters are curious objects and are easily within reach of amateur-sized telescopes. They contain tens to hundreds of thousands of stars and range five to fifty kiloparsecs distant. Spherical in shape, hence their name, they seem to be special members of our galaxy. They have been observed around distant galaxies of different structure than the Milky Way's spiral nature, so they are not unique to our galaxy, or our type of galaxy.
In this view, taken in the Spring of 1988 with a piggy-backed Nikkor Reflex (catadioptric) 500mm telephoto, North is to the right. Taken from a dark-sky site between Tucson, AZ., and Kitt Peak National Observatory. While this photo was taken with color film, I experimented while scanning an 8x10 print. Using the scanner, I converted the same image to Black and White, as well as enlarged the central region two times, and three times.
Recently, I've been researching Globular Clusters and have updated my knowledge of these beasts.

Library

It is important to have an excellent reference resource for research. If you can't afford these for yourself, try your local public library. Here are a few of my favorites, and why:

Atlas of Deep-Sky Splendors, fourth edition, Hans Vehrenberg, Sky Publishing, 1983.
I find this book useful. Though the textual content is somewhat dated, it is still useful today. The consistent scale photographic plates show all of the Messier objects, as well as a few other prominent and sometimes unreachable southern objects for northern observers, which makes this atlas very useful to the Messier observer. Also, the scale is consistent for what observers with smaller instruments will see—very helpful for finding these objects the first time.

The Night Sky Observer's Guide, two volumes, Kepple & Sanner, Willman-Bell, 1998.
Split into two volumes, Autumn & Winter, and Spring & Summer, detailed information on the Deep-Sky is available going well beyond the Messier catalog, with drawings from various sizes of telescopes. A wealth of observing information.

Observer's Handbook, published annually, The Royal Astronomical Society of Canada.
Compact in size, and loaded with about the best emphemeral data any observer will need to keep pace with a constantly changing sky.

Uranometria 2000.0, two volumes, Tirion, Rappaport, & Lovi, Willman-Bell, 1987.
Best compromise in finely detailed star charts, and format for use with observing. The limiting magnitude of the atlas matches my 9x60mm finderscope which can be useful in picking objects out in the sky. Second edition soon to be available. The Deep Sky Field Guide contains the reference data, chart-by-chart breakdown by object type, errata/addenda, and overall supplements the Atlases nicely.

The 20-cm Schmidt-Cassegrain Telescope, Peter L. Manly, Cambridge University Press, 1994.
Even if you don't own an SCT, this is a valuable and practical observing guide covering a wide variety of interests. Somewhat dated, still very useful. I had checked this book out of the library, and decided to buy my own copy even before I finished reading it.

Millennium Star Atlas, three volumes, Sinnott & Perryman, Sky Publishing Corporation/European Space Agency, 1997.
If you can afford this atlas, you won't regret it. Just a few examples of what you get for the money: correctly oriented for position angle of galaxy plots, huge scale, more deep sky objects, limiting magnitude of 11 to 11.5!

Also ...

I hold the Astronomical League's

My first astronomy club membership was with the Spokane Astronomical Society from 1973-1974. I have served as member of the Executive Board, Vice-President, and President (youngest to-date) of the Denver Astronomical Society, with membership over three periods: late 1974-1980, 1987-1995, and 2000 to present. I am also a member (2001-) of the Northern Colorado Astronomical Society and (2001-) of the Longmont Astronomical Society. In the spirit of a new club for a new century, I helped found the Aurora Astronomical Association.

I started the DAS Members List Serv, and I now I run an eGroups list called Astronomy: General.

I am a MAPUGger .

I am list administrator for the FRAC.

I teach Astronomy to sixth-graders at the Jefferson County, Outdoor Education Laboratory School, here in Colorado.

I am a member of the Association of Lunar and Planetary Observers (ALPO), active in the Mercury section, and also belong to the International Dark-Sky Association (IDA).

... and I helped to construct the first pads at the DAS Dark Sky Site .

The newly poured pads see first light.

My observation interests are:

I also am interested in photography of eclipses, deep sky, the Sun & Moon, and wide-field regions.

Read the Star Naming FAQ!

Just how many planets are there anyway?

You might enjoy (hate?) reading about my nearly complete FilterQuest.

I am definitely a Meade-Lover and you can read my LX200 tips page.
