Winged_Hussar, w Learning The Basics Of Astrophotography Editing
@Winged_Hussar@lemmy.world avatar

Always appreciate updated and current videos on the process, even if I can’t mimic on Linux.

Something that has always frustrated me about the editing process is that every program has its own unique features

Some you get wavlets

Some you get stacking and aligning

Some you get level adjustments and curves

All while most of the programs are deprecated and/or abandonware

I think currently I have Registax, Auto Stakkar, Siril, PiPP, and Gimp installed for processing just because some programs perform features better than others.

The polarisation of the broadband emission shows the flux density of two orthogonal polarisations is anti-correlated with temporally shifting spectral structure observed.

abcdqfr, w 1.5TB of James Webb Space Telescope data dumped on the internet — new searchable database is the largest window into our universe to date

Tangent, how would this telescope do turned around and pointed at our deepest oceans? There’s infinitely more alien life to actually find and study, and it’s still unstudied for good reasons I suppose I’m fishing for.

Wait… what?

We’ve got tons of oceanographic satellites. James Webb is extremely good at picking up light. The ocean is extremely dark.

Okay quacks, time to go data-mining for anomalies!

This is the planet wide equivalent of the microwave interfering with the wifi signal.

Geodad, w Starlink Satellites Are 'Leaking' Radio Emissions

They were designed by a capitalist. Why should this surprise anyone?

The object was to get a product to market as quickly and cheaply as possible.

Corners were cut and mistakes were made.

frunch,

Corners were cut and mistakes were made.

This is my assumption about nearly all modern tech. We’ve reached the point where it’s practically standard practice to release unfinished products and/or software. In many cases, it ends up being a particular person or small group of enthusiasts that end up finishing and polishing the product.

Not only that, but support for many tech products is shorter-term than ever. I was talking to a mechanic recently who was surprised to be informed by Alfa Romeo’s parts department, that they did not offer replacements for a particular part for the brake lines on a car that was less than 10 years old…and referred the mechanic to find a seller on eBay who makes them. There was indeed one company making the part and selling them on eBay. That was the aftermarket support, lol!

RedSnt, w Milky Way may not be destroyed in galactic smash-up after all

But don’t worry either way:

Phew!

no galactic smash-up is expected for billions of years, long after our ageing Sun will have burnt away all life on Earth.

What do you mean after all? Wasn’t it the consensus since forever that there was basically 0 chance of anything actually colliding because galaxies are mostly empty space? I’m pretty sure I read about that when I was a child.

Much more likely is that the galaxies will zoom relatively close to each other – say, a little under 500,000 light years away.

In To Sleep In A Sea Of Stars by C. Paolini, there is a group that aims to prevent or circumvent the heat death of the universe, although the post-human civilisation has barely touched a few star systems (<30 ly). In a similar fashion, I recommend to take the necessary steps to build up a galaxy defense force soon.

Timecircleline, w Milky Way may not be destroyed in galactic smash-up after all

The one thing I had to look forward too. Dang.

Nougat, w Milky Way may not be destroyed in galactic smash-up after all

Even when the galaxies do collide, the number of stars passing close enough to each other to disturb any planetary systems is zero.

LodeMike, w Milky Way may not be destroyed in galactic smash-up after all

Near nothing in the galaxy would be destroyed anyway because most of space is empty.

True but the aesthetics of the galaxies would be totally wrecked.

LodeMike,

😭

Glad to hear it, I’ll uncancel my milk delivery.

Everytime he is mentionned this webcomic en tête springs into my mind, and I can’t help giggle out of it.

Took me a minute… I have to jump through many self made hoops to get new websites through my firewall’s DNS filter and I don’t enable http. It is however on archive. I’m probably the only nerd here with such masochistic network, but whatever. Thanks for the comment. Tycho was a character, that’s for sure.
