This question is only somewhat tongue in cheek.

 

Why is so much of out equipment black?  We enjoy our hobby in the dark.  Is there anyone here who has not fumbled around looking for a black lens cap on the dark ground in the middle of the night?  I have no money at all but I think I'd pay a premium for white or yellow cables that would show up in the dim light of my red headlamp and be easier to avoid tripping on.

 

I know certain parts need to be matte black to cut down on internal reflection, but cables?  Lens caps? The external parts of anything? 

 

I love the fact that my ES ED80 is white.  The black carbon fiber version looks way cool in the daylight but....

 

Anyway, any opinions?

 

Clear skies everyone!

Starlight can often be bright enough to cast a strong shadow. Light reflected from the white equipment can adversely affect night vision.

Could black anodization be cheaper than other colors? Usually the goodies with red, blue, orange, etc anodization seem to be pricier.

I like to think of it as a fashion statement - matches the dark clothes I wear at night.

I am glad my APM/TMB was painted white as it saved more than a couple of bumps in the head.

Black radiates heat faster than white. On the other hand black absorbs heat better than white.

Warning:  the following includes paraphrasing, cross-generational stereotypes, and broad, sweeping generalizations.  Reader discretion is advised.

 

Chrome, silver tones, and gold tones are "old fashioned," superficial, ordinary, common, rote, cliché.

Black is modern... high tech...

Black is cool.

Black is heavy, dark, deep, dense, mysterious, dramatic, primal, magical.

 

Practicality?...  Nah.cool.gif

 

Best wishes.

None of my scopes is black (white, white and cream or whatever the Edge HD color is). Expensive mounts usually are *not* black (Losmandys excepted). The EQ6R-Pro and HEQ5 are white. iOptron has red, white and black mounts. Astro-Physics has white (now that the black Mach1 is no longer in production), Software Bisque has red, 10Micron has black. Celestron is mostly black. 

 

Cables usually are black, but you can definitely get other colors if you want. Dedicated astro-cameras are mostly red or blue. And so it goes. Good counterweights are chrome, cheaper are usually black but sometimes gunmetal gray. 

 

Personally I don't like an all-black look, but some equipment looks nice in black. Also black hides dirt well--I wouldn't particularly want white or yellow cases.

There are good reasons for equipment colors.  

 

- A chair is good to be white, I can see it more easily in the dark. 

 

- A focuser is better black as it's less likely to reflect stray light. Eyepieces are another.  

 

- White and black have different emissive properties. 

 

I buy my scopes used so I take what I get...

Better for stealth viewing. I like my black Skywatcher OTAs.

Thanks for all the feedback!  I plan to put white markers on my cables and some other stuff to make them easier to avoid in the dark.    I agree that the black equipment looks cool.  I'm not as agile as I was a half a century ago so I need to make sure that I'm not tripping over stuff or bumping my head on equipment.  Not to mention that kicking a leg means having to redo my polar alignment.

 

Clear Skies!

Sounds like a reasonable approach - something to mark the tripod legs is useful to avoid the issue you mention.

Because if I want pretty colors, I open a bag of skittles. wink.gif lol.gif

 

Black is Formal. Black does not reflect light, and doesn't mess up your night vison.

 

Carbon fiber is hands down the best telescope tube material available. It has thermal properties that hold the telescopes focus better than other tube materials.

Metal tubes expand and contract with the temperature changes. And those change your telescopes focal length.

 

If you want to, you can always add glow sticks, or kids glow bracelets to your equipment. 

 

Why is the sky black at night? Absence of light? Because the Sun is down?

Nope. So we can see the Stars, Moon, and Planets.

By grand design.

 

Me and Darth Vader like Black.

YMMV wink.gif lol.gif cool.gif smirk.gif

 

Edit in:

But usually, I find I had forgotten to take the lens caps off....

I hate it when I do that! mad.gif
