Disclaimer: It's not often that I talk about my purchases, toys or tools on here. I generally find blogs that do so to be a bit crass and filled with braggadocio. Feel free to ignore this post if you feel it crosses into that territory. However, I sincerely hope it does not.
I finally decided to join the full frame1 crowd this week with the purchase of a D800. Amazon had a few decent rebates and with the sell off of some of my older gear I was able to swing it. I've been mulling over making the switch from DX equipment for a while. It wasn't until I received the camera and spent a little time with it this weekend that I realized exactly what I had signed up for. Here's a test shot I took this Saturday while I was figuring out my way around the controls.

You can read the serial numbers off the fog lights and headlights in that photo.
Now, I do realize that PhaseOne, Hasselblad and Leica have been selling 35+ MP medium format cameras and backs for years however it's still a bit astonishing to me that such resolution is available in a 35mm sized body. Granted there is more to a sensor than resolution and the larger formats blow 35mm away in other areas, but still, just incredible in that package. That's a 24" wide print at 300 DPI, quite amazing.
The downside to all these pixels is the storage and processing needed to handle them. I will probably be adding faster drives and more RAM to the workstation to handle the D800's output. Right now Lightroom seems to struggle a bit. First world problems I guess.
Hopefully I'll be using the camera on a few upcoming projects I'm working on. If everything materializes as it should I might be able to talk about those publically soon-ish. A few of you are already aware of at least one of them.
1. I utterly hate the term full frame when referring to 35mm format DSLRs. 35mm was a fairly small film format and still is in the the digital days. Folks who shoot 4x5 will have a bone to pick with you and your "full frame" D800/5D Mk III.
Fortunately tonight was relatively free of clouds (although the wind wasn't very helpful) and I managed a decent photo of comet PANSTARRS as it set. It's getting harder to spot on the western horizon as the moon has moved away from it, still worth checking out though. It's very hard to see with the naked eye right now and will only get dimmer over the next few days. Having binoculars will help. The photo was taken with my D7000 at ISO 3200, f/5.6 and 4 seconds with the 70-300mm VR.
There's been a lot of hype surrounding comet PANSTARRS. While it will be visible with the naked eye in the early twilight hours it will not as spectacular as Hale-Bopp, Hyakutake or McNaught. That shouldn't stop you from going out for a look, just don't be surprised when it's not a jaw dropping sight. A pair of binoculars will be useful for locating it in the evening twilight. However, you'll need to be careful as it will be fairly close to the sun before March 12th. It's been predicted to hang out around magnitude 2 or so which is about the same brightness as the stars in the Big Dipper or Orion's belt. If it were above the horizon longer after sunset this would probably be a good sight for most people, however the glare of twilight will wash it out substantially.

From about March 12th to 14th PANSTARRS will have a nice pairing with the thing waxing crescent moon. This will make it easier to find and create an good photo op. A normal to semi-telephoto lens will be useful, something in the 85mm + range I'd guess, for trying to capture PANSTARRS. Don't be afraid of a higher ISO either. Second magnitude isn't terribly bright and ISO 1600+ will let you take a short enough exposure that the Earth's rotation shouldn't blur things up too badly. You'll also need a very clear view of the western horizon. At most comet PANSTARRS will only get around 10º above the horizon. That's only about a fist width held out at arms length. Below are a series of screen captures from Stellarium showing the comet's progression over the next few days. You can click to enlarge.
Looking west on March 10th 2013 at about 7:55 PM EDT (6:55 PM EST). Not very high in the sky and hard to spot.

Looking west on March 13th 2013 at about 7:55 PM EDT (6:55 PM EST). One of the best nights.
Looking west on March 14th 2013 at about 7:55 PM EDT (6:55 PM EST). Probably the second best night to catch PANSTARRS.
Again, I wouldn't let any of this stop you from going out and checking it out. Naked eye comets are rare and even small ones are fun to see. Consider it practice for comet ISON later this year. If it holds up to the hype it should be nothing short of spectacular. However, comets are very hard to predict so at this point ISON could do anything between now and December.
2012 is behind us. It was a busy year, it barely seemed like it was there. This past year was the first full year of my life I wasn't enrolled in school or taking classes for anything. I'm definitely not ready to settle on a career for thirty years and retire and I might be back in school before long. Sitting still this long isn't something I'm terribly good at.
With the office move at work I took the opportunity to try out this standing desk thing. Since the budget for new furniture in the office is nonexistent I ended up fabricating my own desk with some cinder blocks and an old workbench I rescued from surplus. The result is a little shaky, but it works.
Curiosity’s findings stole the show on Monday and from a scientific standpoint they are rather tantalizing. Mars leaves a great deal of mystery to be uncovered. However, I believe the more stirring and historically interesting find came from another small nuclear powered probe launched thirty some years ago.
Voyager 1 is currently the furthest manmade object that has ever been sent out from Earth and the Voyager program as a whole is the longest running space exploration mission humans have ever put forth. It was reported a few years back that Voyager 1 was believed to be closing in on the edge of our solar system. Although the readings from the probe's still functioning sensors differed from the expected. This sent scientists back to the models to try and figure out what was going on. After some time to ponder and some new data coming in over the last few months it appears that the Voyager 1 craft is indeed nearing the edge of the solar system. I won’t weight you down with the specifics; the official NASA release on the data is very in depth for those interested.

The significant thing here is the fact that a piece of human technology is on the cusp of interstellar space. After traversing millions of miles, making close encounters with the outer planets, diligently radioing back a wealth of data the outer most reaches of our tiny, backwater solar system Voyager 1 is about the break loose and continue on a journey to the stars.
Think about that for a minute. Just sit back and take it all in.
It’s easy to lose track of the significance of such an accomplishment in an era where humans living among the stars is common in our fiction. Considering the fact that the first airplanes were put into service just over a century ago and the first orbital flights of unmanned satellites happened just over sixty years ago this is an astonishing accomplishment. In age where GPS and nearly instantaneous worldwide communication are available to nearly everyone it’s hard to imagine just how far we’ve come in such a short time. A century is just the blink of an eye on the cosmic scale, barely enough time for a few generations of even our own species to come and go. In that same time we’ve survived numerous threats to our very survival. Most of them caused by own our technology and ambition, the very same thing that has sent humans and our robotic counterparts to other worlds. Yet, here we are, about to leave the boundaries of our cosmic backyard.
Voyager 1 is the forerunner. The first step in what I hope will be a continued age of discovery and exploration. Once it crosses the heliopause we can say humanity has left its mark not only on the Earth or the solar system, but also on the galaxy. We’ve ridden our proverbial bicycles across the street into unknown territory. Truly a testament to our own potential, to what can be accomplished by a few simple primates working hard on a small greenish blue planet in the nondescript corner of the universe.
After applying to a few NASA Socials this year I was finally accepted to the Radiation Belt Storm Probe launch. I’m pretty excited about the whole thing and actually looking forward to the drive down to Kennedy Space Center. The launch itself is taking place on August 23rd at 4:08am. I’m not terribly fond of the launch time although it should still be dark at that time of morning. I hear night launches are spectacular and that should more than make up for the early wake up time.
The mission will focus on studying the Earth’s Van Allen Radiation Belts and how the sun influences these phenomena. I’m hoping to learn a great deal more about the mission during the briefings at KSC this week. Solar science wasn’t really my research focus in undergrad or grad school so I don’t know a great deal about it. Understanding the solar weather and the radiation belt environment is essential to future satellite and spacecraft design.
Please use caution when viewing the sun! Viewing the sun without proper protection could damage your imaging equipment or vision! Sunglasses and standard ND filters are NOT sufficient protection!
This week has been a busy one in terms of solar activity with sunspot AR1476 taking center stage. It's fairly large as sunspots go at roughly 7.5 times the size of the Earth and actually visible to the unaided eye with proper viewing protection. Any set of eclipse viewing glasses will allow you to safely view the spot. I recommend the AWB glasses from Woodland Hills Telescopes. The proceeds from the glasses go towards Astronomers Without Borders. Surprisingly enough the spot hasn't sent any massive flares or ejection our way as of this post.
Photographing solar phenomena isn't quite as hard as it seems. Using my usual Induro BHD1 ball head, a sturdy tripod, the Orion Short Tube 80, glass solar filter, and Nikon D7000 with appropriate adapters I managed to capture the shot below. The trickiest part is actually aiming the scope at the sun. The best way I've found so far is to watch the telescope's shadow and adjust its positioning until the shadow appears its smallest. Sort of like viewing a sun dial at noon. Of course none of this is a problem with higher end go-to models.

Yes that photo really was taken in the middle of the day. Good solar filters knock out around 99% of the incoming light, hence the black sky. The orange tint is due to the filter glass, the sun is actually closer to white in color. I have some Baader solar film on order that will hopefully be here later this week. Apparently it produces a less color shifted image. It's hard to get ahold of right now since most of the solar filter equipment is on back order due to the approaching transit of Venus.
Even if you're telescope-less a set of eclipse glasses are a cheap and easy way to checkout our nearest star. They'll be especially useful this June for the transit. Which, by the way, is the last one for the 21st century. You won't get another shot.
