For the vast majority of things in the sky, they'd see black. This stuff is incredibly dark, and we need hours of exposure time to get enough signal. Even after hours of exposure the raw stacked frame is a black field with some pinpo

The problem is that the noise can swamp the signal. Another example of this would be doing astrophotography during the day. The sun doesn't block anything, it just makes the sky glow with "noise". Theoretically it has exac

I don't remember exactly what I did, but I do remember running into that kind of problem. I probably used starnet2 to remove stars before doing much processing, and recombining stars towards the end.

I've seen some pretty impressive stuff done with a relatively cheap / simple DSLR setup. The basics of astrophotography aren't that expensive, but it gets exponentially more expensive to meaningfully "zoom in". Bec

Haha, yeah. I could go on for hours. I've had to learn that most people really don't want a lecture series on the finer points of astrophotography. Seabass's comment was pretty much perfect; a bit of detail, but not so muc

It's a wonderful niche/technical hobby, but it's not cheap. You could even say it's "pay to win". I didn't buy all of my stuff at once, and I had some mistakes, but I'd guess I use on the order of $

Oh nice! Except for Alnitak (I love me some spikes), I like yours more.

Well, if you think photography is too easy you could try taking up astrophotograhy :)

Thanks, but it if you look closely you'll see that the Webb image has almost an image worth of detail within each pixel of my image.

Thanks! I hadn't gotten to writing this out, but you've pretty much nailed it. > They most likely used a secondary camera whose sole purpose is to guide the mount and keep it pointed at the target object. I did use a guide cam

Absolutely incredible. For a little bit of context for how impressive this is, here's my take on it with a consumer grade 8" Newtonian telescope from my backyard: https://www.astrobin.com/full/w4tjwt/0&#x

I've been using terraform for 10-ish years, and this is very much not how I feel about it. Terraform absolutely makes life easier; I've managed infrastructure without it and it's a nightmare. Yes, it can be awkward, and yes

Yes, you can :) It all depends on the properties of the signal and the noise. In photography you can combine multiple noisy images to increase the signal to noise ratio. This works because the signal increases O(N) with the number of image

I think this is a really important comment, and until about 6mo ago I would have completely agreed with you. I even made these same arguments with my coworkers; it's just cooperative multithreading, it's making up for a defect in

In a language like C that isn't really possible because the language can't keep track of all of the places that memory address is stored. If malloc were to return something like an address that holds the address of memory allocate

Amateur astrophotographer here. What I'm going to talk about is true for my rig. The JWST is astronomically a better telescope than what I have, but the same basic principles apply. The cameras used here are more than 8 bit cameras,

Yes, they can be. Self-diagnosing isn't a great idea; lots of non-depressed people have some symptoms of depression. It would probably be a good idea to find someone to talk with though.

Every place I'v worked has celebrated fixing things that have broken, and forces engineers to fight for prevention. It's not exactly celebrating things breaking, but it sure looks a lot like it.

I'm not saying bankruptcy is bad. It's a necessary escape hatch for the credit industry, and shouldn't have the stigma it does. maunder is absolutely right; the consumer credit industry in the US is nothing but predatory.

Creditors love people who have recently filled for bankruptcy. They're vulnerable, known to be bad with money, and can't file again for a number of years.

by cconstantine 5y ago
This is a lie that needs to die. Bankruptcy might get removed from your credit report, but the public court records never do. Anyone who does a credit check can (and will) search those public records. Bankruptcy stays with you forever.

The only thing that matters is revenue, and if it can't be easily measured against revenue it doesn't exist. I am so tired of this line of reasoning. It's poisoning the industry, ruining products, and sucking the joy out of
