Powerful new camera developed to directly image exoplanets – Astronomy Now
While NASA is famed for the occasional convoluted acronym, the camera team came up with its own prize winner: DARKNESS, which stands for “DARK-speckle Near-infrared Energy-resolved Superconducting Spectrophotometer.”
The DARKNESS camera can take thousands of images per second without the “read noise” and other factors that affect more traditional cameras. It also can determine the wavelength and arrival time of every photon striking its detector.
OK, that's cool. But I have a question. Why does this "new" camera look sort of weather beaten in the pic?

First line was "being developed" - implying what you're looking at is still under construction. Sheet metal, for example, often comes with text on it when shipped from the mill. That would, for example, explain the dirt-like marks on the top.
I'm sure they'll spray paint it or something when it's done.

spray paint? It's NASA, not some bogan workshop.
Usually they gold leaf space stuff for the radiation protection. The leaf is so thin just touch it and it'll peel off onto your finger no matter how well you wash. Gloves wont help either so thin just a little rub and it'll tear the leaf.
(Those little blobs are only a few micrograms, scientists wont get rich scraping gold leaf off their finger tips even after a lifetime's worth.)

Gold can be hammered, do to it's extraordinary malleability, to a film 6 atoms thick.
So, any sensible person would use gold spray paint.

NASA (in fact all satellite builders) always uses gold leaf, never spray.
I'm sure there's a good reason why, too lazy to look right now.

I should have used the jokey face.
Amazing you took me seriously on the spray paint, twice.*
* NASA would never spray. The mist could get into the equipment. They always use those paint markers[^] to avoid that.

Use an artist's paint brush, rub on face to build up a little static, pick up the leaf and "paint it on". So simple even an old fool could do it... oh wait.. I don't have any. Traded all mine for bitcoins. 
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

It looks like the instrument mounting on the telescope is actually the weather-beaten part. The camera itself (the black box?) seemed pretty clean.

I'm basically putting together a new guitar with an old body.
I got a combination of Seymour Duncan Hot Rails and Cool Rails and now I'm figuring out the potentiometers. (1 of them has to be push/pull  ).
The wiring scheme says 250 Ohm, so I got that (though I don't know what the difference 250 vs 500 actually does), but there is also a difference between a logarithmic ("audio") and a linear potentiometer. I read you should use the logarithmic ones since they don't "cut-off" at the end. Is that both for volume and tone (I need 1 volume and 2 tones) ?
Any other advice I should take in account for the potentiometers, eg how do you know what knobs will fit on those meters?
Any advice on the switch itself (5 way switch)?
thanks

That's easy. 3D print your own knobs that fit.

Volume pots should be log taper, otherwise all the action is in a few degrees at the bottom end. Remeber that loudness is essentially logarithmic. Tone, it depends on the circuit. If you fit a linear one and all the effect is concentrated at one end, then go log (or antilog, which can be hard to obtain).
Knobs: Most older pots had a 1/4" dia shaft with a flat for a grubscrew. Newer ones (here, at least) have a nominal 6mm dia, splined to suit push-on knobs. You can't put a splined knob on a 1/4 shaft, but you can do the opposite, and it's all horrible and wobbly.
Good luck,
