Everyone ought to have a Hubble Space Telescope

For some amazing, really amazing, photos of space and beyond (or within) check out:

I was referred by a friend on the Winter Solstice day, Dec. 21, 2020.
You won't believe some of the unearthly views and earthly ones. Great stuff.

My Hubble is on back order. Technical issues.

My technical issues are with the bank.

Everyone DOES have a Hubble Space Telescope! It's OURS, the People's. Oh, its caretakers won't let us drive it which, at my age, is a good thing. But, you have apparently just stumbled into the vast cache of imagery that is available to EVERYBODY, at no extra charge (just pay your taxes, is that too much to ask?).

It's my understanding that the Hubble Telescope CMOS sensor is only about 1 MP. That was the going state of the art in 1990 when it was launched. Don't know what kind of lenses they have in front ot that sensor but they've obviously made some amazing images.

I’d guess the one million pixels are all in a single row and that it operates like a scanner. None of the subjects are moving very fast across the Hubble’s field of view. IIRC everything in view is actually moving directly away from the Hubble, all at the same rate, so there’s no lateral displacement of the image details, IOW no subject motion blur.
“Shutter Speed” is a rather interesting mind bender, in that a whole lot of the subjects had already vanished long before the Hubble photographed them.
Even the idea of focused distance is a bit tricky cuz it not only looks across mega mega gazillions of miles of distance, but also across billions of years of time. That is why it’s such an expensive project ... cuz time is money !

I do the next best thing: look at the pictures NASA took. I don't really need to take my own pictures.

They ARE your pictures (if you’ve been paying US federal taxes). Enjoy !!!

I've been admiring the Hubble Images for a very long time. My favorites are "Star Birth Clouds - M16", and "Gaseous Clouds - M16".
Science fiction is not nearly as beautiful as science fact. The images are so "out there", that you just couldn't fabricate those images.
One of the amazing things was the "eye" operation done by NASA astronauts when the telescope didn't produce good images.

Tax money very well spent! I wish I could say that about all our taxes.

Yes it is to much to ask when they are over 55 percent for a guy who makes 35000 a year. It makes me feel like a fool to work more for the government than I do for myself. Still love America and don't want to leave because here I can complain and not worry about them kicking down my door. Lol. At least so far. Lmao

55% taxes at slightly over the poverty level ? Your tax prep person is a really hopeless moron. Get someone else.

I had to send mine back. Everything was out of focus.

Here is a picture of a Hubble Sensor duplicate. It is actually made up of 2 rectangular sensors bolted together into one square sensor. Each half is 2K x 4K = 8M pixels. Together, they are 4K by 4K = 16M pixels.
A bit hard to figure out the physical size of this sensor, so let's guess about 8 cM by 8 cM. That being the case, each pixel is about 20 uM by 20 uM. That means each pixel can capture a lot of photons.
Plus, Hubble mastered the art of Dithering to improve the resolution. See:

I feel a bad attack of GAS building up!
