Touring the Backbone of Cygnus, the Swan

In the late days of northern summer, the constellation Cygnus lies nearly overhead in the mid-evening hours. A long, conspicuous constellation, Cygnus stretches along the diffuse arc of the Milky Way and is packed full of lovely deep-sky objects for stargazers of all skill levels.

Cygnus is an ancient star group and goes back at least 2,000 years. In Greek legend, Cygnus was a friend of Phaeton, the son of Helios, the Sun god. Phaeton met his demise while foolishly trying to drive his father’s sun-chariot across the sky. When Phaeton fell into the river Eridanus, Cygnus begged Zeus to turn him into a swan so he could fly down to retrieve his friend’s body. In doing so, however, he gave up his immortality. Zeus was touched by the selfless act of Cygnus in honoring his friend, so he cast the swan in a place of honor in the night sky [Read more…] about Touring the Backbone of Cygnus, the Swan

Almost Heaven (Star Party), West Virginia

Once in a while, you have to get yourself to dark skies. Forget the excuses, the lost sleep, the long drive. Just go. It will regenerate you, reconnect you to the cosmos, and help you remember why you became a stargazer in the first place.

Which is why I powered down the computer and packed a simple Dobsonian telescope, a binoviewer, and a couple of eyepieces and headed out to the Almost Heaven Star Party (AHSP) in West Virginia, an event held this year on September 2-6, 2016 [Read more…] about Almost Heaven (Star Party), West Virginia

Jupiter finally fades from view this month but it goes out in style, attended in the west after sunset by brilliant Venus and, at the beginning of the month, by a slender crescent Moon. Mars lingers in the starry sky of Scorpius and Sagittarius, and finally starts to move eastward and pull away from Saturn and Antares. And the Sun reaches the September equinox and marks the changing of the seasons. Here’s what to see in the night sky this month… [Read more…] about The Sky This Month – September 2016

Vixen’s Astonishing SG 2.1×42 Wide-Field Binoculars

While Galileo’s profound discoveries with his first telescope in 1609 are rightly celebrated in the annals of science, the optical design of his first telescope is not. Based on a simple convex objective lens and a concave eyepiece, Galileo’s early telescopes gave drinking-straw-narrow fields of view and and image brightness that dropped off drastically at the edge. His design was quickly replaced by the so-called Keplerian telescope which we all use today. So imagine my surprise when I discovered a relatively new set of binoculars from Vixen Optics that are based on a modern version of Galileo’s original telescope design. These Vixen SG 2.1×42 binoculars, which magnify just 2.1 times and have objective lenses 42 mm diameter, give extraordinary wide-field views of entire constellations, and some say that observing with these binoculars is like having ‘super vision’ [Read more…] about Vixen’s Astonishing SG 2.1×42 Wide-Field Binoculars

As befits a large constellation at the edge of the Milky Way, Ophiuchus is packed with deep-sky sights for observers with small and large telescopes. Open and globular star clusters abound here, along with many fine double stars. Let’s have a short tour of a handful of the highlights of the constellation, moving from easy objects to more difficult sights [Read more…] about Touring Clusters and Stars in Ophiuchus
