This Week's Astronomy Video

Sagittarius: Open cluster M7, the globular M22, and the nebula M8

A LOT to see in the sky here! Sagittarius is looking in towards the center of our Milky Way galaxy. This video takes an 'outward-in' approach. First, you'll learn the naked eye stars visible in the area, including some of nearby Scorpius. Next, trace the outline of the "Teapot" asterism within Sagittarius. Though not visible directly, learn where in Sagittarius to be looking towards the supermassive black hole at the center of our galaxy, Sagittarius A.

After that, break out the binoculars, as Messier 7 - though technically within Scorpius - is easily found from the "spout" of the Teapot. At the "lid," learn where Messier 22 can be found, which is one of the most spectacular globular clusters in the entire night sky. Find it first with binoculars, then move on to a telescope for an even more glorious view. 

And finally, use some of those same "lid" stars to locate the Lagoon Nebula, also known as Messier 8. This emission nebula is one of the brightest in the sky, but it also is the birthplace for the stars of open cluster NGC 6530, which all appear to be superimposed on top of the nebula. It's like getting two objects to view in one! 

Are you new to all this astronomy and telescope stuff? Eyes on the Sky's "Ultimate Guide to Telescopes and Amateur Astronomy" can have you up to speed on a lot in about an hour.

Eyes on the Sky astronomy videos are now closed captioned, allowing for translation into 58 languages as well as benefiting people who are deaf or hard of hearing.  Or, watch at work! Just don't tell your boss.


Beginner to amateur astronomy? Start here.

With tutorials on how to align and use an equatorial mount, a six-part series on telescope basics, and three videos on getting started stargazing, the "Ultimate Beginner's Guide to Telescopes and Amateur Astronomy" literally shows you in about an hour how to get started.

And because unexpected events occur (like supernova, comets and other phenomena), special astronomy events videos are occasionally offered.  Plus there's a full astronomy glossary and downloadable Greek alphabet PDF.  For the do-it-yourself folks, see the DIY-astronomy section - save money on astro equipment, or build it for the satisfaction of having done so.

"Dark-sky friendly lighting fixtures"

I talk about dark sky friendly lighting fixtures a lot - I mention them in most every video, in fact.  But what are they? Find various types of dark sky friendly lighting fixtures here, or try these lighting manufacturers - and if you still have trouble locating them, contact me.  NEW AS OF JANUARY 2013: The U.S.-based home improvement store Lowes now carries dark sky friendly lighting with the IDA seal of approval - look for them in your store. Got a neighbor with a light shining in your bedroom or window somewhere in your home?  Here's how to approach a neighbor about poorly shielded lighting.  You can also find the silver-crown light bulbs highlighted in previous "Dark Sky Facts" from these online retailers:

Support "Eyes on the Sky" and light pollution reduction

Making "Eyes on the Sky" every week isn't free.  Not only do I spend 10 to 12 hours on each 5-6 minute video by the time I research, write, shoot, create graphics, edit and upload each video, but some graphics, music, costumes and other things I add all cost money.  So I'd ask one of two things from you: Please either change your own outdoor lights and encourage your neighbors to do the same, or donate a bit towards my efforts to spread the word through these videos.  Even as little as $5 helps - yes, really - but what would help more is a monthly subscription of $3 a month.  That's only $0.69 an episode!  And you don't even need a Paypal account; you can donate or subscribe with any major credit card you see in the button graphic.  Thank you - I appreciate your support!

Solar viewing and safety

Viewing our closest star, the Sun, can be fun - and potentially dangerous if done wrong or with unsafe methods.  For more information about solar viewing and safety, please click here.

Beginners to stargazing have lot so questions about telescopes, like what types are out there?  How do I calculate magnification?  What eyepieces should I get?  What is barlow lens?  Get your questions answered here, quickly and easily, at the Informational Videos page. 

Special event astronomy videos about the supernova in M101 or the peak brighness of Mira, are available in the Special Events page.  

Last year's "Eyes on the Sky" videos may be found in the 2011 Videos area.

Star Charts

Free stuff is good, right?  How about free star charts so you can find things in the free videos discussed in "Eyes on the Sky" videos?  Click on the Star Charts linkfor PDF star charts you can download and use to see 'what's up!'

Not enough you say?  No problem!  Learn the stars that you can see each season of the year - even from light polluted areas - with these guides that take you through the constellations step by step in winterspringsummer and autumn

What else you ask? How about free videos that help you with stargazing, like how  to align an equatorial mount to the celestial pole, or why planispheres are a useful tool in astronomy.  You can find those resources in the Informational Videos section.
