Hubble Trubble
By David Russell 7/11/2015
Putting a fork into myths about Hubble's Galaxy classification

The Visible Matter – Dark Matter Coupling Problem
By David Russell 8/28/2013
In the current model of the Universe favored by most cosmologists the composition of the Universe is ~4.5% visible (baryonic) matter, 22.7% non-baryonic dark matter, and 72.8% dark energy...

The Likely Place RV Resort
By Tony Hallas 8/15/2013
... a beautiful grassy field for tent campers ( empty ), spotlessly clean bathrooms with hot showers, very nice camp sites with some shade trees right by the grassy field, a nice restaurant ... and if that wasn’t enough ... a challenging, well maintained 18 hole golf course! All this under the darkest skies in the US.

Classification of Planets and Moons in the Solar System – A New Proposal
By David Russell 7/24/2013
The definition of a planet and where the division is between Solar System objects that are planets and those that are not planets is currently in a state of disagreement among scientists.

A Visit to Questar and Parks
By Barry Kawa 7/18/2013
In the summer of 1997, on my quest to interview the great commercial telescope makers in American history for a book, I made a pilgrimage to one of the most famous small towns in telescope history: New Hope, Pennsylvania.

Telescope Nothing

An Interview with Thomas A. Zappetti of Unitron
By Barry Kawa 6/13/2013
In August 1997, the rumors were flying among amateur astronomy circles about the demise of Unitron. Certainly, their ads had long disappeared from the pages of magazines they once graced, such as Sky and Telescope...

Telescope Nothing

Interview with Al Nagler of TeleVue
By Barry Kawa 5/30/2013
The first time I saw a Tele Vue refractor was when I was responding to an ad in the Cleveland Plain Dealer in 1995 for a Brandon 94mm refractor. I drove to the seller’s home in Mentor-on-the-Lake, and admired the baby-blue Brandon on a Unitron alt-azimuth mount, set up on the back porch overlooking Lake Erie. But another telescope next to it really took my breath away. It was a brass Renaissance on a Tele Vue Panoramic mount. “Are you selling that one?” I asked. I liked the Brandon. But I really wanted the Renaissance. I ended up buying both.

The first in a running series :-)

The Mount Boys: Losmandy and Byers
By Barry Kawa 5/23/2013
In the world of commercial telescopes, if Byers mounts are the Mack trucks of telescope mounts, then Losmandy mounts are the Dodge Ram trucks. The two companies are only located about 120 miles apart, in North Hollywood and Barstow, but both seemed on the other side of the world from each other, in scale, size, market and old school and new school philosophy.

An Interview with Barry Greiner of D&G Optical
By Barry Kawa 5/9/2013
But after visiting Norman and Robert Edmund, I had a choice. Go see the sights in Philadelphia, like the U.S. Mint and Independence Hall, with my wife? Or spend the afternoon at D&G Optical talking to Barry Greiner about telescopes?

An Interview with Steve Kufeld, Inventor of the Telrad
By Barry Kawa 5/2/2013
On a trip to Southern California in June 1997 to track down some of the influential figures in the history of commercial telescopes, I hoped to find Steve Kufeld, the inventor of the world-famous Telrad telescope sighting device.

Interview with Tom Johnson of Celestron
By Barry Kawa 4/26/2013
In the spring of 1998, Tom Johnson was living a comfortable life in retirement in Palm Springs, Calif., after being out of the telescope wars for some 18 years and having sold Celestron to Diethelm Holding Co. of Zurich.

Interview with Norman and Robert Edmund of Edmund Scientific
By Barry Kawa 4/15/2013
Before World War II, if you were well-to-do and wanted a telescope, you could buy one from Tinsley Laboratories, J.W. Fecker, the old Brashear Co. in Pittsburgh and the venerable Warner and Swasey. If you weren’t wealthy, you had to build it yourself. That’s the world Norman Edmund entered when he got his start selling surplus optics by mail order.

An Interview with Dick Nelson of The Optical Craftsmen
By Barry Kawa 4/8/2013
In 1977, when I flew to California to track down and interview former commercial telescope makers, I was under the impression by talking to some people in the industry that Dick Nelson of The Optical Craftsmen was deceased. But Tom Cave in Long Beach told me

An Interview with John Diebel, Founder of Meade Instruments
By Barry Kawa 4/1/2013
In 1997, Meade Instruments Corp. stood at the top of the telescope market. It went public that year, and was the darling of smaller issues. Its products were innovative, industry changing and in demand, such as the Autostar Computer Controller and the ETX 90 Astro. The Meade 90 ETX had been introduced the year before and, at $495, the waiting list to get one was incredibly long. John Diebel, the company founder and, at that time, chief executive and chairman, welcomed a visitor in his office at Meade headquarters in Irvine, Calif...

By Barry Kawa 3/25/2013
This is the story of Criterion Manufacturing Co. of Hartford, Connecticut, makers of the legendary RV-6.

An Interview with Tom Cave - by Barry Kawa
By Barry Kawa 3/21/2013
the summer of 1997 took me to Long Beach, California, to talk to Tom Cave, the founder of Cave Optical Co., at his home there, where he had lived for almost 60 years. I had a 10-inch Cave reflector in my garage in Cleveland Heights that was a pleasure to use and my personal favorite. So, when I called Mr. Cave, it was an honor to speak to him, and he greeted me warmly and invited me out for an interview...
