@493633cc I just did a short timewarp video (1440p), and explored the interface a bit. That's it, I haven't even tried any of the high resolution or framerate modes yet. A cursory online check says this battery has a 45-90 min life depending on the recording settings, but so far it seems mine performs well below that. And I'm still puzzled by the significant charge drop while the camera is off.
I need #help with the #battery life of my #GoPro Hero 7. I got it for free 3 years ago, brand new, but I haven't had the chance to use it until now. After ~10 minutes of very light #video usage, the battery level went from 100% to 70%. It then dropped to 66% overnight with the camera off. All wireless connections are off, wake on voice too. I'll keep an eye after more battery cycles (this was the first charge) but I wanted to check if others have had the same issue. What am I missing? Thanks!

Joking aside, the laser excites sodium atoms 80-90 km above the ground, making them glow. This creates an artificial "star" whose twinkling we monitor in real time. This information is then sent to a deformable mirror that reshapes itself many times per second, correcting atmospheric turbulence and delivering crisp images.
@1d31eacc Thanks! Yeah, that pattern is due to interferometry. I toned it down a bit with respect to the original data, but I didn't want to remove it entirely, I don't like it when the background looks completely smooth in astronomical images.
Do you want to learn about the amazing #engineering behind large optical telescopes? Tom Scott recently visited ESO's Paranal Observatory in #Chile, and in his latest video he tells us all about it, including a sneak peek at our Extremely Large #Telescope !

@4464071c I'd say it's a new form of an old thing. A heated argument between, say, Marvel and DC fans is fundamentally no different from a similar argument between fans of two football teams. Both situations feature people identifying strongly with something that isn't truly connected with them in any meaningful way; football just happened to be mainstream much earlier. Mandatory Mitchell & Webb sketch about this 😉 https://www.youtube.com/watch?v=xN1WN0YMWZU
Ever wondered why astronomers need so many different telescopes and instruments? Different colours or wavelengths of #light tell us a lot of information about the objects we study.
In the latest episode of Chasing Starlight we tell you how we use this "super-powered vision" to capture what our eyes can't see.

@b8de0890 For a brief moment there I thought that was Heidelberg & the Neckar, but I was confused by how different the castle looked 😅 Adding Cochem to my list of places to visit!
Here's a sneak-peek of the cell that will support the secondary mirror of ESO's Extremely Large #Telecope.
This mirror is 4.25 m wide, the largest optical secondary mirror ever on a telescope. Heck, it's even larger than the *primary* mirror of many current telescopes!
This cell was made by Sener in #Spain.

@f604b7a1 It depends on what part of the infrared range we're talking about. In the so-called mid-infrared, the absorption/emission of our atmosphere is more prominent. The ELT will have an instrument called METIS that will observe at these wavelengths. Besides taking very sharp images it can also take very high resolution spectra. This complements JWST, which focuses more on sensitivity. You can find more info here, including a short movie about METIS: https://elt.eso.org/instrument/METIS/
@f604b7a1 At somewhat shorter infrared wavelengths – what we call the near-infrared – these atmospheric effects are milder. Other ELT instruments will observe at these wavelengths, like MICADO: https://elt.eso.org/instrument/MICADO/

As someone who works in #communication , I'm baffled by some folks here on #mastodon who talk down about users of other #SocialMedia platforms in a patronising or even insulting way, only to immediately add: "I don't understand why they don't come here!"
From a goal-oriented comms point of view, this makes zero sense if your true goal is to drive people here, no matter how well justified your criticism of other platforms might be.
I really like it here, but come on folks... 😉
