President Obama, you’ve put your foot in it.

Much as I like you, Mr. President – and I definitely do – you have really put yours foot in it this time. I’m not a sycophant. I don’t agree with all of your positions. For instance, I think your stance on gun control is outright unconstitutional, while at the same time, I understand why you’d prefer that it were otherwise, and, since the system itself is corrupt and largely unconstitutional these days, why you’d be willing to violate your oath in order to see things done the way you’d like them to be done.

This isn’t stupid; it’s calculating and it is very much political, “just the way things work today.” For instance, if you actually think the government presently is authorized to restrict citizens from owning arms, I’d love to sit down with you and show you why you’re 100% wrong. I think you’re far too smart to buy the standard arguments for your own position, though, and I suspect that in private, you’d simply admit that is the case. I understand political expediency. I also understand an urge to do good, and that the legalities of the system can frustrate that urge if not pushed to the side.

But this time… I’m disappointed in you.

Hackery for my auroral photo pursuits

sssssTrying to figure out if there is an aurora, and if it can be photographed, really requires looking at some different kinds of data. One is the earth’s magnetosphere; how disturbed is it? That’s what causes auroras. That information has to be obtained from the GOES satellites, or magnetometers on the ground (I find the satellites to be a better indicator.) Another is the weather – if it’s cloudy, give up now. Then visibility comes into play – fog will kill the opportunity just as quickly as clouds. You can get that from NOAA (or whoever is your local weather provider if you’re not in the US.) But what if the moon is above the horizon? That’ll kill it too, at least, if the moon is showing any significant crescent. And of course, along those same lines, the sun has to be below the horizon. The moon and sun information can be calculated.

After repeatedly looking all this stuff up, and occasionally forgetting an important issue (like, is it cloudy?) before I drove out to my dark viewing area with my camera gear, I finally decided to pull all the information together into one handy place. And here it is, sized to fit on my iPod’s display, too. Further, since all the data is in one place, I have the underlying engine SMS me if conditions are right for an aurora; also, as long as I keep a browser open to the page, the page auto-refreshes.

The underlying processes keep an eye on things for me, updating their snapshots of satellite data and weather and lunar and solar states every five minutes. So I can be out and about, and if things look hot, I’ll get a text message on my cellphone. How cool is that?

Avatar arrives

AvatarMoviePosterSo Deb and I don’t go to theaters any more, we wait for the Bluray. Today was the big day that Avatar arrived, and instead of chess night, we had a movie night (usual suspects.) Brian, Evan, Deb and myself settled in after a nice dinner to see what all the fuss was about.

If anything, I think the movie was under-rated. What a feast for the eyes, and what fun, too. I was able to ignore the silly native-American and global-warming themes and just dig on the whole sci-fi-ness of it; the only thing that sorta bugged me was the musical portion of the sound track, which I can only describe as the Lion King on crack. But the rest was so good that mostly, I just ignored the silly drumming and the crazed new-age sing-a-longs. Which, thankfully, didn’t make up a large part of the movie.

There was quite a bit of other eye candy of numerous kinds — the biota of the world, the corporate headquarters virtual mapping system, the blue folk themselves… really a tour de force. I am so glad we bought the hi-def Blueray; it looks bleeding awesome on our 1080p home theater.

I really loved the ‘Mechs, larger-than-human armed and armored exoskeletons that remind me of baby MechWarrior or MechAssault ‘Mechs from the video and table games. I have a pretty good collection of Mechs (about 2…3 inches high, from the table game) and it tickled me to see things like them handled so well in a movie — definitely for the first time.

There have been some rumblings about DRM incompatibility with el-cheapo and/or poorly supported Bluray players out there; I’ll repeat the advice I give everyone about Bluray players: You want a Sony PS3. You don’t want anything else. Period. There is no doubt, no decent competition, no comparable bang-for-the-buck. The PS3 is it. And the PS3 will play the Avatar Blueray without any problems whatsoever.

Anyway, just thought I’d throw this out there. Great movie. On the (very) off chance you haven’t seen it, you should. This one goes to eleven.

My camera is back!

Here’s a shot I took with it today. The RAW image is definitely very pinkish-red, but as I was told, it’s not a rough job to correct for the additional red sensitivity. I think, because the red is so hot, I’m losing a little dynamic range in the normal regime as well, but as you can see here, it’s not a severe problem. Now if the weather will give me a break, I’ll give the camera a real workout on some emission nebulae!

Review: Canon EF 85mm f/1.8 USM Lens

c85mm

The Canon EF 85mm f/1.8 USM Medium Telephoto Lensis a moderate weight (15 oz), very well built lens. It does not come with the appropriate hood, the Canon ET-65 III. You get both a lens cap and a mount cap, all packed inside tight conformal foam to protect the lens during shipping. There’s also a very brief manual and the usual warranty paperwork.

The lens offers AF and manual focus, and allows manual focus even when AF is set to on, a very useful feature for low-light and other challenging focus situations. This is a USM lens, and as a direct consequence focus is fast and precise, just as you’d expect.

The AF/Manual switch is in a reasonable location, close to the camera body. There is a range indication on the barrel of the lens behind a transparent window which serves to keep dust and debris out of the workings of the lens. Manual focus is controlled with a broad, easy to manage textured ring about mid-body on the lens. During focus, nothing external on the lens body moves or rotates, so there are no complications for using polarizing filters, and no concerns about the lens “pumping” air and so causing dust contamination in either the lens or camera with use.

So I sent my camera off to be modified…

…for hydrogen-alpha infrared. This mod will give it about 3.5 times the sensitivity to the glow of emission nebulas, and so enhance my ability to shoot astro photos.

Astrotrac — Adding tracking to Astrophotography

3952232557_5923d1aa8d_b

So, after a couple of years of working with untracked astro photo techniques, and a fair amount of success, I finally gave in and got a tracking system. I went with the Astrotrac because of the advertised light weight, easy setup, and long, accurate tracking capability (2 hours, advertised.)

I’d seen some pretty spectacular astro photos, considerably better than mine. So I bit.

On "The Price of Freedom"

The price of freedom is risk.

The price of safety is conformity, restriction, and repression.

You can bank on it. Our leaders certainly have.
