The difference between spending billions on one camera compared to spending a couple thousand on a full system.
Also, it’s much easier to get a high-res image from something immobile.
Also, storing a few high-res images takes a lot less space than storing hours/days/weeks/months of high-res videos.
Doesn’t JWST have to account for its own orbit around L2 and stellar parallax (depending on distance)? I assumed it would have to have some tracking.
True, but those are minute parallax changes, not “entire view angle in 8 seconds”.
I have no idea, it just made sense in my head that when you’re cropping such a small portion of the picture, any movement would be visible and would probably fuck up data. In my mind the lens(es?) are in constant motion while in use. Itty bitty tiny little movement, but movement.
I mean, there’s probably a good reason the JWST costs billion and I can get a camera for 12 bucks. Your questions are probably one of the many reasons.
I think you misspelled 10s of dollars on a system…
Multiple billion $ camera vs 30$ camera
Billions of dollars spent and not even a single person captured in the photo? What a scam.
Those galaxies are maybe slightly bigger than that dude.
I think it’s also relevant pointing out that the telescope maybe, possibly, perhaps, cost more than the security camera.
Just by a little bit.
You make it sound like Galactus robbed a 7-eleven.
left picture is underestimating the distance by about 2.5 factor
The problem with security cameras is that insurance demands them, but does not state a minimum quality. Which is stupid, but obviously they see more profit in security being a theater instead of real stuff to prevent incidents.
So if your contract just demands video cameras at every corner and X days of retaining the video, how much would you invest into high-quality, high-definition cameras and quality-retaining video storage?
You can actually buy “outdoor security cameras” for $10 a piece - or you can buy professional stuff for $500 or more. You can store hours after hours of video footage of 16 cameras on one old, worn-out video tape, or invest tens of thousands in disk arrays to store high-resolution video streams. Guess what businesses do when the only requirement is to “have a video surveillance system”.
Clearly the optics involved are different…
If the situation were reversed…
Man doesn’t the world suck you guys? We’ve got all this money for high res cameras to defend capital, but hardly any pixels dedicated towards the advancement of humankind.
