Discovery Channel Telescope Snaps Inaugural Pictures 66
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

The "market" consisting of the cable company oligopoly, right?
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.

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'.

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.

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.

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.
