Discovery Channel Telescope Snaps Inaugural Pictures 66

Posted by Unknown Lamer from the space-is-always-cool dept.
eldavojohn writes "Two decades ago ... Discovery Channel teamed up with Lowell Observatory and embarked upon a $53 million adventure: the fifth largest telescope in the United States funded entirely without state or federal money. The very first photos snapped with its 16 million pixel camera are in and they look beautiful. Yet to be seen are the simultaneous spectroscopic and imaging observations that should be provided to researchers by the DCT's Ritchey-Chretien instrument cube. Located near a dark-sky site (Coconino National Forest), scientists hope to use this new telescope to answer many research questions including how our solar system formed and how dwarf galaxies evolve. For more telescope porn, check out the DCT's photo tours. Luckily 'the process of planning and building the telescope is due to be featured in a one-hour Discovery Channel documentary set to air in September 2012.' Perhaps there is hope for Discovery Channel to return to its former glory?"

            • It's worse than that; each package is usually a superset of the preceding package. And channels like Discovery tend to be in the basic package, so you don't get a choice to have it or not, unless you don't subscribe to cable at all.

              What I'd like to know is how they determine ratings these days. In the old days, the "Nielsen families" had extra boxes monitoring what they watched. These days, with cable boxes, they can have them report back to the cableco what people are watching, so I imagine they do that

              Good point, but the market I was thinking about is the mass people who decide whether to tune in to educational programs about astronomy or a puerile drama about a couple of retards building shitty motorcycles and constantly arguing with each other.

              Presumably the latter is winning on this one, unless the execs just happen to like motodrama more than they like money.

      • ...and as long as they are included in standard cable packages so they can get their franchise fee whether anyone watches them or not, they'll continue to head down crap lane with cheap reruns of shoddy programming.

    • Sadly there is a bigger audience for watching people wade around in swamps, go to pawn shops, dig antiques out of crazy people's backyards etc than for actual documentary television. The amount of crap on the channels that used to play interesting documentary type programing is depressing. We are rapidly headed back to the situation in the 70's when the only place playing that kind of programing is PBS. Though even that would require them to back off their steady stream of "Antiques Road Show".

    It's not the fifth largest telescope in the United States. It's the fifth largest optical telescope in the continental United States. There are several larger optical telescopes on Mauna Kea, in Hawaii.
    • It doesn't allow simultaneous observations, either. It's near-simultaneous observations due to the mirror switching that happens in the DCT's RC cube - currently only one of three instruments have use of the telescope, depending on how the mirrors are oriented.

      Astronomy and terrestrial photography have somewhat different requirements. The telescope sensor is probably huge, each active site has to be as large as possible to gather any stray photons. Typical cameras are APS-C sized or less... they're more interested in being 'fast' rather then 'sensitive'.

      • Even for astronomy imaging, 16 megapixels isn't so impressive for "the fifth largest scope in the US." There are many amateur astronomers across the country imaging with CCD cameras based on KAF 16803 chips (4096 x 4096 pixels). Open an issue of "sky and telescope" to the pages where they present a gallery of readers' images, and you're very likely to see something taken with a 16 megapixel camera. They're high end cameras from an amateur standpoint, no doubt about it, but not super special. Think about

          Of course, it's all in the details, isn't it? At the very least, there's the question of how well cooled the sensor is to minimize heat noise, and beyond that, it could be something like an L3CCD, where you're literally counting every photon that hits the sensor. I have no idea what hardware they're actually using.

        Correct. The LMI's CCD is 6144x6160 15um pixels (92.16 mm x 92.40 mm) ref [lowell.edu], or 8500 mm^2; this is over 20x APS-C, 10x full-frame 35mm, and 6x the 9um KAF-16803 (and its 12um sister KAF-9000) mentioned in a sibling post.

        For comparison, an APS-C sensor with the same size (15um pitch) pixels would be ~1650x1100; summing over nxn pixel bins to get a resolution in that vicinity from a higher-resolution APS-C CCD will be close, but somewhat less sensitive, as more pixels means less fill factor.

        they're more interested in being 'fast' rather then 'sensitive'.

        What?! You know fast

    • Once it's above a few megapixels I personally care way more about the optics.

      However in this specific case I wouldn't be surprised if this particular camera -- if it's even sensical to convert to ISO speeds -- is on the order of ISO 0.02441... (1000 times more light sensitive than ISO 25.)

      First, the submitter got the value wrong. The Large Monolithic Imager (LMI) has 36 MPixels (technically, it has 6144x6160 = 37,847,040 pixels), not 16 MPixels.

      http://www.lowell.edu/dct_instruments.php [lowell.edu]

      Second, being a scientific instrument, it has a rather lot of requirements that your Nikon doesn't; the number of pixels is only one of several parameters engineers trade against each other when building a camera for scientific use.

      • Correct, 38 megapixels, still peanuts in the world of gigapixel astronomy cameras (Pan-Starrs, HyperSuprime-Cam, etc) but the deep-depletion E2V CCD is in a different class than an SLR CMOS senor and a lot of interesting things could be done with it. Sometimes an instrument is so expansive it precludes risky science but something this size could be used for a lot of interesting things. Especially interesting is that it's a single chip. Most CCDs that size are mosaics but this one is a single massive chip,

  • The "full sized" images on their website make me rage a little. First off, for a 16 MP camera, they can do a little better than 0.5MP image on their website.

    Yea, it could have been scaled down, but that is a minor gripe compared to them publishing a telecope image as a HIGHLY COMPRESSED JPEG.

    Seriously? Most of the stars and gas clouds in that blasted image are lossy compression artifacts.

    Why couldn't we have a nicely sized PNG?
  • What is with the bright center spot? Is that just millions of stars packed way more densely than on the spiral arms?

  • That the word "Inaugural" caused me to think the telescope took pictures of the Presidential Inauguration.

    I eventually read enough to realize this is a newer telescope, which would have made photos of any presidential inauguration unlikely. But since we're talking about powerful telescopes, I guess even the time travel element wouldn't be out of the question.

  • Does a privately funded scientific facility produce better science than a public one? For one thing, if a "science news" conglomerate owns its own facility, won't it naturally be biased towards reporting on discoveries made by itself?
  • We will never see this telescope mentioned on the Discover Channel again unless it involves a reality show with a group of rednecks who auction off dates with B-list celebrities to go logging in the nearby national forest.
