IC342: An Obscured Spiral Galaxy, Hiding in Plain Sight

The galaxy IC342 ranks as one of the under-appreciated gems of the northern night sky. As you can see in the image above, this elegant nearby spiral galaxy in the far-northern constellation Camelopardalis (the Giraffe) is a photogenic target for experienced imagers. But it’s rather challenging to see visually in all but the darkest skies. It is, however, worth the effort to see this swirling assembly because it lies in an unusually beautiful field of foreground stars [Read more…] about IC342: An Obscured Spiral Galaxy, Hiding in Plain Sight

The Sky This Month – October 2016

October 1, 2016 by Brian Ventrudo Filed Under: Celestial Events

harvest_moon They’ve put on a brilliant show in the past several months, but Saturn and Mars slowly fade into the sunset this month in the southwestern sky. The two planets, along with the Moon and Venus, are a beautiful sight on Oct. 3-5 in the southwest. The Orionid meteor shower also peaks this month as the Earth passes through a stream of debris from Comet Halley. And there’s a “Black Moon” this month, defined as two New Moons in a single calendar month (as defined in Universal Time). Here’s what to look for in the night sky this month… [Read more…] about The Sky This Month – October 2016

The Blinking Planetary Nebula

September 23, 2016 by Brian Ventrudo Filed Under: Deep Sky

While the Milky Way along the backbone of the constellation Cygnus, the Swan, offers many fine targets for stargazers, the wings of the constellation are also well worth exploring, especially in the months of July through October when the constellation lies near the meridian. In this short tour, let’s tiptoe through the western wing of the Swan and inspect the remarkable Blinking Planetary, NGC 6826, and a few more intriguing deep-sky objects [Read more…] about The Blinking Planetary Nebula

Mini-Documentary Shows Incredible View of the Night Sky

Infinity ² from Uncage the Soul Productions on Vimeo.

Here’s an incredible video that’s as close as it comes to the actual feeling of being under a clear dark sky. Created by Ben Canales and John Waller of Uncage the Soul Productions, this short work features 20 high-school students at a summer astronomy camp in Oregon. The producers simply ask, “What do you feel?” The film also visits the Oregon Star Party where 600 astronomers camp out with their scopes.

This isn’t a timelapse. It’s a video of the night sky in real time. It shows what’s possible with current camera technology, in this case a Canon MH20f-SH set at ISO400,000, along with a fast 20 mm Sigma Art lens.

In this video, along with wide-field views of the late-summer sky, you can see stars reflected in the primary mirror of a big Dob as it turns, a live view of the star Capella through an eyepiece, and a view of the Perseid meteor shower. Just amazing.

Touring the Backbone of Cygnus, the Swan

September 16, 2016 by Brian Ventrudo Filed Under: Deep Sky

The Milky Way through the constellation Cygnus. The dark cloud bisecting the Milky Way is the Great Rift.

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
