Meteor 8/11/12

Persied Meteor

The Orionids. As the name implies, this meteor shower has a radiant point in the well-known constellation Orion. Orion rises pretty late still, but the optimal meteor watching time is after midnight. This shower peaks on about the 20th of November, but as with some other major meteor showers, meteors can be seen days in advance and after the peak. 10-20 meteors per hour is expected.

While you’re in the area, you might want to check out some of winter’s best dso (deep sky object) jewels. M42, the Great Nebula in Orion, is easily visible and quite lovely in Orion’s sword with a good set of binoculars. A few constellations over is Auriga, the charioteer. In it are two star clusters, M36 and M37, with M35 nearby. These visibly close clusters are some of my favorites; they are spectacular through my 15×70 binoculars.

Enjoy the Orionids!

Meteor 8/11/12

I didn’t come away with many meteor photos, but this one (to me) stands out! This was taken on a tripod, a thirty second exposure with the aperture wide open and ISO 1600. To the upper left of the meteor is Cassiopeia. See the fuzzy blob at the right? That’s M31, the Andromeda Galaxy. COOL!!

Another Astro-event that is a do-not-miss! This is not quite the largest meteor shower, but it certainly is the most popular. It lasts several days, and peaks in the very fist hours of the 12th. Here are a few tips:

Stay Late: The later, the better. The absolute best time is after midnight, when we are turned farthest from the sun (although I have seen some good ones in the evening). Coincidentally, the shower also peaks just after midnight. Don’t plan to come out after 2 a.m., though, as the moon will have risen; although it’s not full it will drown out fainter meteors. Bottom line, Midnight-2 a.m. is the best time.

Go Dark: Go someplace where an astro-guy’s old enemy isn’t. Light pollution is pretty much everywhere these days, and it will drown out the fainter meteors. If you can’t, it’s o.k. Lots of meteors are visible in modest amounts of l.p., and bright ones will shine through even some of the hopeless places.

Dark Adapt Your Vision: If you stay out for about an hour, your eyes will convert to the awesomeness that is dark adapted vision. You may have noticed that when you go out at night and look at the stars, the stars will appear brighter when you don’t look directly at it (using peripheral vision, also called averted vision). If you stay out about an hour (even half an hour noticeably helps), your eyes will change so that direct vision will be brighter. But this means you can’t bring any light source. No cell phones, no flashlights, nothing. One glance at white light will destroy your adapted vision and you’ll have to wait another hour. Of course, this means being in a place without street lights.

Use Red Light: Wait, don’t lose all hope! As it turns out, red light doesn’t destroy adapted vision like normal light. So if you have a red flashlight, use it. It comes in handy, especially when trying to read star charts. “It can be any color, as long as it’s red…”

Look North/NorthEast: The Perseid Meteor Shower (which is annual, by the way) is named as such because meteors from this shower appear to radiate from the constellation Perseus (located in the Northeast these days), but meteors come from all over the sky. Looking North will put in the position to see the radiant point, though.

And, here’s a personal tip that I’m sharing, I learned this from watching past meteor showers:

Keep Your Eyes Moving: Ok, so you’re thinking, what? That’s it? It is. It really helps. If you keep staring at one star, your mind will wander, your eyes will start to close, stars will spin before your eyes… then FLASH. “What? Was that a meteor? Where? Man, I wish I had seen that one…” If you keep your eyes moving from star to star, learning new constellations, noticing star colors, etc., it will keep you alert. And sooner or later a beautiful meteor will streak through the atmosphere.

Enjoy the meteor shower (who knows, it might be a storm!).

It finally cleared up at night here in Maine, so I was able to pull off some astrophotos just as the moon rose. In the below picture is the area of the sky near Cassiopeia. The streak is a shooting star (click on it if you can’t see it); this is the fist time I have been able to capture a noticeable one!

We also built a campfire, so we all sat back and relaxed after a hard day’s work. I had some fun shooting the fire; I changed the White Balance to make the fire more yellow like the photo below (you can actually go to the menu and modify the tone, as in more yellow, red, blue, etc.; in Nikons go to White Balance, push select, choose the wb you want, then push the right cursor button, i.e. the right side of the little ring button thing. You can move across the chart for the desired tone).

For the below photo I stopped the aperture as far down as it would go, set it at the lowes ISO, and shoot a 4 second exposure. Doesn’t it create a cool effect?

Stay tuned!

Lyra

In the night sky tonight is the annual  Lyrid meteor shower. Although it peaks tonight, you can still see meteors from a meteor shower a day or two before and after the peak. The image above (from StarryNight software, I added the point where the shower is) shows where to look. To see it, it is best to go out sometime after midnight, as it is darkest then. Look up and eastward. The bright star Vega in the constellation makes it easier to spot. Don’t worry if you can’t find it, meteors can come from anywhere in the sky. It will be enough to just look eastward. This year it should be easier to spot even the fainter meteors this year, having no moon to contend with. The Lryids come from the dust and rock of Comet Thatcher. Also in the night sky is our own galaxy, the beautiful Milky Way, declaring the Creator’s glory (Ps. 19:1). If you have dark enough skies, it is quite as sight!

Dress warmly (if it is cold in your area) and clear skies!
