>> mfw when idiot thinks seconds is a measure of resolution

300 arc seconds

>>1575789
shut up and go catch space herpes

>>1575789
>my face when you dont realize that when dealing with telescopes, arc seconds are the unit relating to resolution
look it up on wikipedia under the astronomy section. Arc seconds are used to denote resolution in astronomy

>>1575802

Lol wikipedia isn't reliable you fucking faggot. Seconds are a measure of time not resolution.

>>1575809
Yes, seconds ARE a measure of time. ARC seconds are a measure of degrees, and in astronomy, that correlates to resolution.

>>1575823
No, he's right, seconds just measure time.

>>1575823

>> Mfw faggots don't realise seconds only measure time

>>1575833
I think the dudes here "not knowing' what an arc second is are trolls who know exactly what it is.

>>1575841
>>1575833
ARC SECONDS ARE A MEASURE OF DEGREES, AND IN ASTRONOMY, RESOLUTION!!!!
FFS just look up arc seconds on google you dipshit

>>1575841
arc second A unit of angular measure of which there are 60 in 1 arc minute (or therefore 3600 in 1 arc degree).

that's from Harvard's website you dipshit.

>>1575833
>>1575809

And:
>>1575789
seems to genuinely be that stupid.

>>1575853

LOL Google is even less reliable than wikipedia.

Fuck this thread is so full of trolls.

>>1575849
That's quite a theory, fella. Where's your evidence?

>>1575841
>mfw you ignore the "arc" part of the name, which implies degrees

keep on trollin'

>>1575861

ITT: Trolls making up science

>>1575875
Lol at the trolls making pics to prove their pseudo scientific bullshit.

THERE. THAT IS A FUCKING LINK TO HARVARDS DICTIONARY. IT LISTS WHAT A FUCKING ARC SECOND IS YOU DUMB SHIT!!!!!! ITS A UNIT OF ANGULAR MEASURE

Hey idiots has anyone heard of minute of arc in relation to accuracy of firearms? Minutes/seconds of arc aren't a measure of time.

>>1575853
>implies he know how to use google, yet didn't just google "hubble angular resolution"

Welcome to 4chan, OP. This is what we affectionately refer to here as trolling. People are now laughing at the anger they've evoked in you, which is pretty much the purpose for this website.

>>1575881

Wow. You obviously misread the whole fucking definition you fucking idiot. A second is how long it takes light to travel 300,000 metres.

>>1575888
Well, these stupid dumb fucks proclaim to be smart, yet dont even know what a fucking arc second is for fucks sake! jesus fucking christ!

>mfw people still believe seconds aren't only for time

>>1575890
WHAT THE FUCK ARE YOU TALKING ABOUT YOU DIPSHIT IT FUCKING SAYS IN CLEAR ENGLISH THAT AN ARC SECOND IS A UNIT OF ANGULAR MEASURE
ENGLISH MOTHERFUCKER DO YOU READ IT?

Work it out man!

First difraction peak is approximately 1.22 l/d

For visible light (average 550nm) with a 2.4m aperature diameter you get a diffraction limit of approximately 3*10^-7 radians or approximately .06 arcseconds. Becuase diffraction limited optics are achievable especially for a big budget program like hubble, lets state that the resolution is .1arcsec in the visible range

>>1575894
>mfw OP still doesn't get that he's being trolled.

>>1575894

You're the one proclaiming to be smart, and you fucking think seconds measure resolution!

>> my face

>>1575905
http://hubblesite.org/hubble_discoveries/hstexhibit/telescope/about.shtml

THAT IS A FUCKING LINK WITH SPECS ABOUT THE HST IT FUCKING SAYS THAT IT HAS AN ANGULAR RESOLUTION OF .05 ARC SECONDS YOU DUMB FUCK THATS WHAT AN ARC SECOND IS A UNIT OF ANGULAR MEASURE YOU DUMB FUCK SHUT THE FUCK UP IDIOT

>>1575902
>mfw you used "mfw" and didn't even post a picture

>>1575914

Op just get the fuck out. I'm not gonna click onto your fucking bullshit crappy pseudo scientific sites you've found to support your ridiculous theory.

>>1575922

>my face when I have no face you fucking facesist.

>>1575922
you're supposed to use your imagination

>>1575920
WHAT THE FUCK ARE YOU TALKING ABOUT ITS THE FUCKING HUBBLE SPACE TELESCOPES WEBSITE YOU DIPSHIT LOOK UP ARC SECOND IN YOUR FUCKING DICTIONARY YOU DUMB SHIT FUCKING KILL YOUR SELF!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

>>1575930

You still going on about those fucking stupid sites?

Look I could bring up timecube, because it has as much scientific grounding as this bullshit theory about seconds measuring resolution.

>>1575914
>mfw OP knew exactly what the Hubble's angular resolution was before he posted his post implying he was guessing and asking if his guess was right.

You can set resolution in pixels or in dots per inch (dpi), but you can't set it in seconds, OP.

>>1575941
Actually, no. I guessed based on what my dobsobians resolution was, and the size of the HST. I'm surprised that I was spot on.

Wait what? Isn't seconds a measure of time?

Learn to use the metric system, OP.

ITT: Faggots thinking they know everything about science, and trying to use seconds to measure resolution.

HEY I KNOW GUYS, LETS USE MICROGRAMS TO MEASURE TEMPERATURE
