Solar Eclipse on Aug 21, 2017

There is a major eclipse over much of North America this month. The sun will go dark during the day right in the middle of a cloudless day. An eclipse is when one object completely blocks another. If you’re big on vocabulary words, the word that describes this as a syzygy, which is a straight [...]

International Asteroid Day at the Las Cumbres Observatory Open House

Having recently visited  UCSB's Sedgewick Reserve at the foothills of Figueroa Mountain in the Santa Ynez Valley, I was eager to learn more about the organization, people, and equipment comprising the Las Cumbres Observatory Global Telescope Network, commonly shortened to LCOGT Network or simply LCO. LCO's very first fully automated research telescope was installed in [...]

Lunar Eclipse

The total lunar eclipse of April 15 lasted about 3.5 hours between late Monday and early Tuesday, with the Earth's shadow slowing darkening the face of the so-called "Blood Moon" in a jaw-dropping sight for stargazers willing to stay up extra late or rise super-early for the event. The lunar eclipse peaked at 3 a.m. [...]

Successful Talk with Dr. Dave Mitchell

Very full meeting last night! Dr. Dave Mitchell spoke to about 85 people, including a bunch of youngsters who asked as many questions as the adults!

John Dobson

We lost one of the true giants of the amateur community on January 15, 2014. John Lowry Dobson was a popularizer of amateur astronomy. He is most notable for being the promoter of a design for a large, portable, low-cost Newtonian reflector telescope that bears his name, the Dobsonian telescope. Read more about him here.

What’s Up for the December Sky

Key Stars For observers at mid-northern latitudes, the Pleiades star cluster is due south around 10 P.M. local time. Above it is Perseus, flanked by Auriga and Cassiopeia.

Constellation Photography by Lee Coombs

One of my earliest projects when I first started doing astrophotography was photographing all the Northern Hemisphere constellations. These early photos are still some of my most used photographs whenever I give talks yet were the easiest to take. With today’s modern films, one can record all the stars visible with the naked eye in [...]

Photographing the Sun by Lee Coombs

With an abundance of light, photographing the sun may seem like an extremely easy thing to do. It is this abundance of light, which includes harmful infrared and ultraviolet radiation, that presents the problems associated with solar photography. As kids, many of us experimented with a magnifying glass using it to focus the image of [...]

Me and My Telescopes by Jim Carlisle

I started out in amateur astronomer as a kid interested in building my own telescope. At that time, that was the way most amateurs got their scopes, especially if you were too poor to buy one. My first telescope came from the advertisement pages of Popular Mechanics magazine, when I was 10 or 11 years [...]

Me and My Telescope by Dr. Russ Genet

Since I couldn’t make up my mind which of the many telescopes I’ve been involved with over the last half-century was my favorite, Aurora agreed that I could write two articles: one on my past telescopes, and the other on my current telescope. Here is number one. I wasn’t born in a telescope, but from [...]

Me and My Telescope by Lee Coombs

I have always had an interest in astronomy and, while in junior high school, fabricated a variety of telescopes from old eyeglass lenses or any other optics I could get my hands on. My first real astronomical telescope was one I built using a 6-inch f/8 mirror that was given to me by a friend [...]

Me and My Telescope by Aurora Lipper

My telescope was given to me as a Christmas present by my husband. The telescope was the “treasure” of a Treasure Hunt I was sent on, picking up parts and pieces of the telescope along the way (the motor drive was found in the clothes dryer). I had never owned a telescope, or even a [...]

My Brief Astronomy Adventure by Robin White

In 1980 I decided to do something that was very unusual for me at the time….read a book! The book I chose to read was “Cosmos” by Carl Sagan. I know most of you reading this now have read Cosmos at some point in your life and therefor understand the impact it could have on [...]

Me and My Scope by Dave Majors

Although I am still fairly new to the club I have been interested in astronomy for many years. Born in 1958 I grew up alongside the space program. In the early 1960’s I lived in El Paso,Tx where my mom worked at White Sands Missile Range-apparently on classified projects as to the day she passed [...]

On May 20, 2012, an annular eclipse of the Sun will be visible within a narrow corridor that will traverse the Northern Hemisphere of Earth. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring the image of the Sun. An annular solar eclipse occurs when the [...]

Fun with the Sun by Michael Spingler

When I was 12 years old I had my first view of the sun with my homebuilt 8” Newtonian. Ever since that day I have been hooked on solar astronomy. My first solar filter incorporated a Hershel wedge design. This system used a non-aluminized diagonal which was inserted into the eyepiece holder, and very dark [...]

Moments in my Professional Astronomical Career I Would Just as Soon Forget

by Dr. Ray Weymann I have done both theoretical and observational research and there have been some awkward moments in both. Early in my career I was a coauthor on a paper which involved computing the interior structure of the sun throughout its life. Standard practice in scientific research publications is to submit your paper [...]

Me and “My” Scopes by Dr. Ray Weymann

Please notice the quotation marks around the title, because none of the telescopes that have been a part of my life have been "mine"--I have never owned one!
