The author, Stefan Hughes, is a historian/ astronomer with a passion for astrophotography and genealogy (family tree research). His interest for ancestral research and the lineage of families gave rise to his first book "Catchers of the Light - The Forgotten Lives of the Men and Women who First Photographed the Heavens" in which he focuses on the background of the first astro photographers and astronomers 19th and 20th centuries. The second book, "The Ages of Astrophotography" is a must-read sequel which fits well on every astronomer's book shelf!

Seven decades ago, while scanning a Palomar Sky Survey plate of the area around brilliant Regulus in Leo the Lion, astronomers Robert Harrington (no relation) and A.G. Wilson noticed a faint blur of light just 1/2° north of the star. They may have thought at first that the glow was just an internal lens flare caused by stray starlight, but it soon became apparent that they had discovered something very real.

At some point we all wish we had a chair to plant our bum on while at the scope. I’ve written this little ditty to share what I’ve learned so that perhaps you can make mistakes totally different from the ones I made (and I seem to continue making them). Like any woodworker I have my biases, preferred ways to do things (e.g. mortice and tenon joints) but for the observing chairsI present here there are lots of options open to you; consider your budget, skills and available tools to make your choices.

Few amateur astronomers are familiar with the name Robert Jonckheere. Jonckheere was a French double-star observer who conducted research at a number of observatories over his six-decade career, including the Strasbourg Observatory in France, the Royal Greenwich Observatory in England, as well as McDonald Observatory in Texas.

Interferometrically Testing Two Celestron C14 Edge Telescopes

I’ve wanted to interferometrically test the two C14s that I have in my shop to get some good data on their optical quality for some time but gathering all of the equipment needed for such a test isn’t easy and I was hesitant to take my scope out of action when the skies were clear. Since it would probably be cloudy for months on end in winter, December seemed like a good time to try to get it done.

Stardust Gallery LED Lightbox and Metallic Print Review

The owner of Stardust Gallery, Craig, was looking for volunteers to review an LED backlit lightbox containing either a Hubble image or an image of user choice. Since I had what I felt were fairly decent Milky Way images acquired from a session at a dark sky site late last Fall, I thought one of the somewhat processed images might be a good candidate to display inside one of the Stardust Gallery backlit lightboxes, and eagerly forwarded the image to the website.
