Among his many studies are tides, magnetism, and trade winds. He cataloged 341 southern hemisphere stars and discovered a star cluster in Centaurus. He also made the first complete observation of a…

History of Astronomy Part 1

evolved2 There have been thousands of science geeks contributing to astronomy over the centuries and millennia. Here are a mere handful that have been selected from some of the most significant figures. Some of these people are real icons of human history, big thinkers. As Isaac Newton once said "If I have seen farther than others, it is because I have stood on the shoulders of giants."…

LX200 Telescope

Meade 10 inch f/10 LX200 ACF Meade 10" f/10 LX200 ACF



I'll start with that "ACF" part because that tells you what kind of a telescope I've purchased. It looks an awful lot like a Schmidt Cassegrain because the light path is "folded up" into a similar package to a Schmidt. The 10" f/10 suggests a 100 inch light path but the scope is…

Coronado SolarMax

The Coronado SolarMax II 60mm, f/6.6, <0.5A H-α, BF15 The Scope

60mm, f/6.6, <0.5A H-α, BF15.

And here's what all that technical mumbo jumbo means.



The telescope is a refractor and the diameter of the lens is 60mm. The f/6.6 means the length of the scope is 6.6 times longer than it is wide which makes it 396 mm long (but everyone says…

Lightbridge Telescopes

A real light-bucket. Meade Lightbridge Dobsonian Surrier Truss Telescopes



A dobsonian telescope consists of optics which were designed by Isaac Newton in the 1660's, on a mount popularized by John Dobson in the 1960's. They say more than half of all amateur scopes are of this type and I believe it. Many people make their…

Great Star Patterns I Have Known

Dippers come in many sizes. Big Dipper

The most famous of all the dots ever connected. So well-known that people pretend to see it even when they don't. There are seven stars, eight if you count correctly. One of them is tiny, little, and wee, and is attempting to hide behind the…

Autumn Bliss

For those of us who could use the extra help. Capricornus the Seagoat

The name Capricornus has been shortened to Carpricorn by some folks. But that is a very recent thing, like only in the last hundred years maybe. Either way, it means Seagoat. And Seagoat is the oldest known name still in use for anything in the whole sky. People have been calling these stars the Seagoat for more than 7000…

The fish gets bigger every time he tells it. Scorpius the Scorpion

In the scorpion we find lots of bright stars that make an obvious fish hook shape, especially when you ignore the claws that the Romans surgically shortened in order to make Libra. In fact some natives of the south pacific call this constellation "Maui's Hook." You see Maui is one of the gods in the lands down under. His…

Spring Thaw

With great bangs comes great responsibility. Leo the Lion

The big kitty is one of the few real connect-the-dots sort of allegories. It makes a reasonable stick figure of an animal at least. The Chinese call it the horse. It takes some imagination. If you try to connect the dots you may get something that looks like a coat hanger after it's been used to unlock a car door. That's how I drew…

Winter Beast

Did you know that the artist who made the Wall Street Bull was never paid? Taurus the Bull

Taurus is a bull, well half of a bull anyway. The front half. Actually mostly the head, with a shiny red eye. I think he’s been drinking. He’s charging Orion who appears to be perfectly prepared to defend himself from the assault. Orion also appears to have lost his pants but we don’t talk about…

Deep Sky Zodiac

The beaten path that the Sun appears to trod on its yearly trek among the stars is the oldest known method of mapping our way around the sky. So the Sun was the center of celestial attention even before people promoted it to admin of the solar system. That makes a lot of sense to me. I could argue (without much effort) that out of all the thousands of gods that people have ever prayed to for a little help, the Sun is the one that delivers the most tangible… Continue

Ten Commandments of Star Parties

Moving it ahead for daylight savings time was a real bitch.

  1. Shatter not the darkness at the site of observing. Man-made lights thou shalt eschew, save the faint of red.

  2. Thou shalt not illuminate thy headlights of thy automobile, nor the car door shalt thy open before the disconnecting of thy dome light. Even a match strucketh in haste is…
