Milky WOW

Friday, June 29:

With a 10 day old moon setting at 2AM, I decided to head to the observatory, if only to visit with friends and relax a bit.  The sky was mostly overcast, even showing us a 22 deg Moon ring at one point.  As the Moon made it's final plummet around 1:30am the clouds parted and revealed a beautiful sky that was sooo worth staying up for.  We waited patiently for the clear sky to darken after Moonset and opened the roof.  We hopped around Cygnus, Cassiopeia, Andromeda, Lyra, and (of course) Sagittarius.  Notable views of Wild Duck (M11), Dumbell Nebula (M27), Ring Nebula (M57), Double Cluster, and the the gorgeous Andromeda Galaxy.  Unfortunately, it was too late and bright to do any astrophotography with the scope.

The stars started to dance in the eyepieces after about an hour of viewing as we were pushing 3:30am so we called it a night.  Before I packed up the gear I took a 180 degree Panorama of the milkyway from horizon to horizon.

Here's a single frame I took of the Milky Way flowing through the Summer Triangle, which is made up of the stars Vega, Deneb, and Altair.  There's lots of great stuff in there but look hard in this frame to find Brocchi's cluster, aka: the "Coathanger Cluster.

Lightning and light pollution

On Friday 5/25/12 our area was hit with some very severe weather but it was supposed to clear quickly afterward.  So, not willing to waste a day off, I decided to head out to the observatory to wait out the storm.  With the 360 degree view at a nice elevation it is perfect storm watching site as well.  The storm was in full swing when I arrived but it wasn't on top of us yet.  I quickly set up the tripod and using my shutter release to  keep the shutter going at 30 sec exposures, it was dark so no need to worry about over exposure.

Lightning is one of the most impressive and surprisingly one of the easiest things to photograph if you don't over think it.  Don't waste your time trying to snap as it happens, you'll only frustrate yourself.  If you have a nighttime storm just set up a tripod and shoot continuously at 30 sec with a wide aperture, pour some wine and get comfy (and safe).  For a daytime storm close the aperture and use shorter exposure times.   Just make sure to grab your gear when the rain hits if you don't have a rain cover (link is the super cheap one I use).

As the night went on the storm moved south and the stars were visible above the thunderheads. Saturn and Spica are the most prominent objects above the clouds. All these shots were taken between 11pm and 1am.

Here's best shots out of 200 or so:

This is the shot I was waiting for!

Bright stars on the left are Saturn (upper) and Spica (lower)

When the sky finally cleared it was such low transparency and seeing was so poor that we didn't even bother opening the observatory roof.

With summertime nearing, the Milky Way has been rising in time for some interesting photo ops.  I've been trying to get a shot of the Milky Way arching over this particular dirt road or weeks and after 3 different tries I have something finally worth showing.   Last night (5/27/12) I returned to this site located near the very rural Spartansburg, PA.  While very rural you can still see the dramatic effects of light pollution.  I'm anxiously awaiting the airing of the documentary The City Dark on PBS on July 5.  I strongly urge you to watch and in the meantime, if you must have glaring property lights get some motion detectors or sky friendly fixtures and bulbs.  Reconnect with the stars, there's a whole Universe out there.  People need to realize we're part of something much bigger.

TURN THE LIGHTS OUT!

You can put lipstick on an Sbig...

Last night, Jim, Randy and I decided it was high time to break out the SBIG ST2000XCM and get some real photography going.  We spent a good hour or more precision aligning and tweaking the scope.  Mostly I stood in the way watching and at best was a pair of sharp eyes to sight guide stars for alignment while the guys twisted various knobs and timed star movements.

Then, hungrily rubbing our hands together, we hunkered down for the next 4+ hours in front of the computer screen searching for guide stars and refocusing and searching for guide stars and refocusing and...  Now I know this sounds like the epitome of tedium but when spiked coffee and a bit of tequila are involved it becomes an all out astrogeek party.  It really was a blast and we learned a few things even if we don't have photos, the next clear night we'll definitely have something to show.  I believe the biggest problem we had was the sky, seeing was below average making good astrophotography near impossible even if we had all the kinks worked out.

While all this was going on I had my camera aimed at the observatory (with Polaris directly above) for 245, 1 min exposures the entire time.  Hours of star (and astronomer) movement were captured and turned into this timelapse video.

All the frames combined using Startrails for this photo.

And at around 2am as I was about to head home the inner Milky Way made it's grand appearance with the summer triangle riding high in the east.  The observatory is on the left.

Good things to come as summer is truly on it's way.

Last chance at Orion

[Thursday, April 12]
Tonight was my last opportunity to shoot Orion until winter.  It's on the heels of the sun in the southwestern sky in the early evening and is completely out of sight before midnight this time of year.
Arguably, the most recognizable northern hemispheric constellation holds one of the most active star forming regions nearby in our own the Milky Way.  The Orion Nebula (aka: Great Nebula in Orion, M42, NGC 1976) is actually the middle "star" in Orion's scabbard.  If you grab some binoculars and look at Orion's scabbard, the three closer stars lined up almost perpendicularly below the three wider belt stars, you'll see that those three little stars are actually multiple stars in three little open clusters. If you look long enough at (and around; averted vision really makes it pop) the middle group you will see wispy clouds shaped like wings wrapping around the little stars in the center.  Those little stars in the center are a cluster of very young stars called the Trapezium.  The wispy clouds are gas an dust in the process of condensing into stars.  Read an interesting recent post by Phil Plait, the Bad Astronomer on the Orion Nebula.

Here she is, this may just be my favorite photo I have ever taken.  I've been trying to shoot Orion for a long time but without a tracking mount it was extremely frustrating. With my camera piggyback mounted on a Meade RCX 400 it's a breeze. Thanks to the Observatory at Bisbee Hill guys for use of the equipment.

I also pointed the scope at a couple prominent galaxies near the tail of Ursa Major or the handle of the Big Dipper and snapped away.  This is the Whirlpool Galaxy (aka: M51a, NGC 5194) located just under the last star of the dipper's handle (picture the dipper right side up, like a spoon lying on a table).  As you can see, it appears to be a large spiral devouring a smaller galaxy (M51b or NGC 5195) but the smaller galaxy is actually passing behind the Whirlpool, merely gravitationally tugging on it.  This galactic encounter sparks massive star formation in the Whirlpool Galaxy, the pinkish/purplish hues are nebulous regions.

This is the gorgeous spiral galaxy M101 (NGC 5457) also near the end of the Big Dipper's handle.  Find it by looking at the last two handle stars and make an equilateral triangle pointing up (again, think of the dipper as horizontal), at the top of the triangle you'll find M101. There's three other galaxies visible in this image as well.  At 10 o'clock from M101 is NGC 5477 and straight to the left edge of the frame from there is a tiny edge-on galaxy NGC 9071.  The Fuzzy blob at the bottom is NGC 5474.

Another Ursa Major treat, Comet Garrad was visible (it's the green thingy), it was fantastic night!

[4/13/12]
Friday night was a bit hazy and observing was kind of a flop but this was our beautiful horizon.  Nice lineup of Canis Major, Orion, Taurus, Venus, Pleiades, and Perseus' leg.
