I've been meaning to check out this early release Euclid data. It's pretty amazing. I've been watching the image releases and feel like they have a few issues with color balance and clipped histograms. After some investigating I still think that's true. Here's a roughly processed image. You can compare them yourself and see if you agree. https://www.esa.int/ESA_Multimedia/Images/2024/05/Euclid_s_new_image_of_star-forming_region_Messier_78

There are a lot of different ways to check your processing for color balance, but I think one of the more fun ones is to take a look at the diffraction spikes. With well separated wideband data, it always comes out colored like a rainbow. If your diffraction spikes aren't prismatic, things might be off (or you might have a really red star.)

@AkaSci That's a good question that I do not have the answer to. After a cursory search around the internet I can't seem to find an artifacts and anomalies article or page from a handbook anywhere. Not sure where to look.

@markmccaughrean Regardless of these criticisms, people seem to love them. I know I do.

@markmccaughrean I suppose it's a privilege to just be Mom From Modesto and not have to worry about social media unless I want to. 😆

Official campaign video says "unified reich" to describe Trump victory.

Campaign blames the intern.

I guess we should be happy they aren't just doubling down and saying "what's wrong with unity" or whatever.

The Intern.

That doesn't explain anything!
Why do you have lil nazi interns? (we know why)

@futurebird i've got this whole fake intern character built in my mind. hard up for cash, takes the job, puts in as much subversive trolling as possible. but yeah it probably was someone who genuinely thought it was cool along with whoever did the direction and whoever else signed off on it...

My friend sent these photos from Oklahoma. I’m totally amazed! Nothing here yet in Modesto, California.

Glowing reddish purplish sky with stars and outdoor lighting visible at the same time. There's a USA flag jutting out from the left.

Barely visible to the naked eye, but my phone could see it great! Here's a little animation.

A night sky view. Vertical lines of magenta aurora with a faint cyan on the horizon. The lines shift positions while the stars move due to Earth's rotation. There are short dark hills. A few planes cross the view.

The best view was actually right at the start when it first started to become visible. Seemed to taper off after that.
