hahaa! Successfully removed all IR and UV filters from my old Canon EOS 600D, I can do full spectrum, UV and IR photography now!
All of the following photos have been taken with a ~550nm+ lpf, meaning cutting everything under 550nm (blue, purple and uv) off. I love the vibrant pink foliage and dramatic turquoise skies #photography

It's becoming increasingly clear to me that Reflect Orbital's fucking stupid giant mirror satellite, with absolutely NOTHING useful to offer, which will cause countless safety issues, ecological disasters, and destroy the night sky, is going to launch.
A bunch of astronomers and I have sent out a fact sheet about them to a bunch of journalists, but very few are going to write about this. So, let me try posting it all here.
Here's what I know about Reflect Orbital and all the downsides:

We’re already there though… the Starlink model is to orbit and then ‘deorbit’ satellites by the thousands. The standard ‘space guy’ response to any concerns has become some version of ‘that’s ok, we’ll just be deorbiting them all, so nothing’s permanent’ which is, of course, bullshit.
That is true.
But I do not have a mass breakdown for what Reflect Orbital is trying to launch - they have been inconsistent in reporting the size of the claimed mirror. So I cannot say how much they would contribute to atmospheric pollution.
As @sundogplanets wrote, the question is how much of a mess the group makes before this all stops.
Yes, but we need to keep reminding ourselves and others that at scale, ‘deorbiting’ satellites is just another way of saying ‘pumps metals and rare earths into the upper atmosphere’ and there’s no way that could go wrong is there?
@Npars01 @davidtheeviloverlord @datarama The space laser thing* was actually one of those "accusations as confession" statements?!? I couldn't figure out where the absurdity came from at the time. Now, it's perfectly clear. Holy crap.
*when MTG spouted the QAnon conspiracy that Jewish-financed Space Lasers caused the California wildfires in 2018.

In addition to the hazards created by the metallic chaff from Elon Musk's Starlinks that suffer from "Rapid Unscheduled Disassembly" ie they explode regularly; how much easily weaponizable stuff do we want in space?
@Npars01 @datarama
There was a story in Analog science fiction magazine in the early 1980s about this. IIRC, it was a murder mystery. How did this executive get cooked in his office, next door to a green skyscraper where every window:
A) worked as a solar panel,
B) adjusted to track the sun,
C) could also reflect sunlight like a mirror to cool the building.
@davidtheeviloverlord @datarama
My thinking was more along the lines of a collimating lens affixed to the satellite...

What if a high powered ground based laser is pointed to these orbital reflectors? It could act as a directed energy relay and be used as a weapon.
See this post by ToughSF on bsky:
A US company wants to launch a satellite in 2026 that acts as a mirror and reflects sunlight back to Earth. Thousands more are planned. Criticism is increasing.Martin Holland (heise online)
It's worth scrubbing through the EEVblog video she links.
TL, DW - Dave's simple back of the envelope math reveals the sunlight spreads out to a few hundred MILLIwatts / m^2. Not even enough energy to run the power inverters the solar cells are connected to. Recovered energy == zero.
This is Nikola / Theranos level fraud.
@arisummerland
> this is one of the stupidest things I have seen proposed recently. Next thing you know we'll have LED billboards in space or... whatever
This! Sunlight-as-a-Service is like something out of Idiocracy. What's shocking is not that one nutter envisioned it (some of the blue skies brainfarts I come up with are just as far out), nor that a subculture of true believers formed around it. But that people in control of serious resources took it seriously.
@martinvermeer @tml I'll just say that if they have thousands of satellites, they will have to be at many different altitudes. Something at 600km altitudes is easily visible for a couple hours after sunset or before sunrise, which is fully dark - that's when you see all the Starlink satellites.
18x18m is their first satellite size. Large enough to be damaging to your eyes if it's reflecting sunlight and you accidentally look at it with binoculars. I'd say that's a really big problem.
@tml But as I was arguing, it is visible _well beyond_ astronomical twilight, which is when the Sun is less than 18 degrees below the horizon, and still illuminates the top of the atmosphere. I know, I have observed satellites for years.
Edit: as the name implies, 'astronomical twilight' is before the sky is dark enough to make astronomical observations, i.e., really dark.
@martinvermeer But during Finnish summer nights there is more light anyway than what such a tiny orbital space mirror would provide.
The plans of this company are crazy enough as such, no need to use wild exaggerations to fight them. Just simple calculations are enough to demonstrate that it is a scam. I hope.
What the actual FUCK. How dare they? How can this be allowed?
Can we start an actual 'people's Darwin award' and humiliate these dangerous greedy sociopaths into submission?
I remember recently reading an article about... I think it was China, might be wrong... talking about putting up satellites with what I imagine would be significant solar arrays, and then downlinking the power to ground stations as focused microwave beams.
I don't know if that technology is actually feasible, but even then you'd still have to be careful; it might not "blind" astronomers per se, but wouldn't it mess with radio astronomy?
Never mind the other reasons, I'm honestly amazed that anyone thinks this is economically viable.
My guess? It's a scam for venture capital, just like Theranos.
what baffles me the most is also the fact that the FCC (an american regulatory body) seems to be the only one able to accept or refuse that project...
What about all the other countries where these statellites would be passing by?

@startswithabang I wonder if people in places like ancient Egypt bitched about the pointlessness of the gods demanding them waste all their effort and resources building small mountains for them.
"Next thing you know they're gonna want us to put giant mirrors in space to reflect the sun so they can pretend to control that too."
All the various other places...
"Why we building these stupid statues pointing out to sea when we're all dying?"
What makes you think it's really going to happen? To me it just feels like a grift.
As a side note, from time to time I do solar cooking. I've made multiple cookers with various materials. Space blanket mylar is inexpensive, but it tends to break down after a few months. You can use thicker mylar that works for like two years, but it weighs a lot more, so would cost more to launch. UV in space would be worse.
Have I mentioned how much I like Nicole Mortillaro? Great article, includes quotes from @JohnBarentine (there were various good reasons why she didn't interview me for this one, but fortunately a lot of other astronomers besides me are really worried about Reflect Orbital's thoughtless plan)

Reflect Orbital is stupid and will cause countless problems with no measurable benefits.

@Teratogenese @JohnBarentine you're probably not wrong. The company is advertising one of their services as defence.
At the end of the day, all this technology has some connection to killing, torturing, or spying on people. I can see this as a heat ray, yes, or as a means of torturing people by exposing them to constant light. It would make it easier to monitor people too in otherwise dark places.

Liberal politics in a nutshell
DarkSky International just posted their position letter on Reflect Orbital. It is direct and to the point:
"Based on current scientific evidence, DarkSky does not see a viable pathway for such systems to align with responsible lighting principles or with our mission to protect natural darkness. These systems would introduce significant ecological, human health, safety, and astronomical risks at a global scale."

Trump is a doctor and Musk a scientist. 🤣
Is that strictly necessary, though? The people that come to mind, apart from actual scientists I know personally (who would probably not want to be known in any wider public sense) are those who have taken it upon themselves to become science communicators, often with unpleasant side effects like harassment.
I‘m happy for scientists to science away in peace. Lots of scientific achievement is a collective effort anyway.

Let's not. Kids are people, not property to be muted at a whim. If they have something to say, the government has no business stopping them from saying it in the place where the general public will hear them, and in 2026 that place is social media.
Frankly I'm shocked at how quickly freedom of speech flies out the window. When I was in school, I was taught that freedom of speech is sacred and our ancestors died for it! Am I the only one who took it to heart?
And what would you sacrifice it for? The convenience of not having to set up parental controls on the devices you give your children? That hardly justifies the burden you'd impose on everyone else.
Are you perhaps worried that your kids will find some other adult who will give them another, unlocked device and social media account to use? Because even with age verification they can still do that!
@argv_minus_one @oberstenzian
When I was a teenager, I learned to make decisions about my own behavior. Yes, I did things that my parents disapproved of. We kept talking, and got through it with growth for us all.
With my own son, my wife taught me that the important part was to maintain communication. That means listening as well as speaking. Forbidding behavior shuts down that communication.
Talk of what you want, not what you don’t want.
This! Kids aren't stupid. They can be reasoned with. In fact they *must* be reasoned with; they don't learn anything from unexplained commandments.
And does anyone else remember their own childhood? Sometimes I was rash and arrogant, sure, but I wasn't dumb, and neither were my fellow kids. We figured out for ourselves how to stay safe online.
Now I'm supposed to believe that kids these days aren't born with brains? Baloney. Of course they are.
@argv_minus_one I use parental controls. I’ll gladly accept more parental controls.
I’m opposed to any forms of age check bs. Especially the methods being rolled out currently.
I think commercial social media entities should be held criminally liable for allowing children on their platforms. And any sleazy ID or age check racket should be forbidden.
They’ll have to come up with a better way to prevent liability. *Like going out of business.*
@argv_minus_one My ancestors didn’t die for freedom of speech. They died to escape slsvery. And the enslavers were demanding freedom of speech for their fellow landowners, not the folks that tilled the soil.
Nationalist myths aren’t a starting point for this. But I get what you mean.
I don’t think social media as we know it was designed for freedom of speech. It can allow for it… but that’s the problem. The *allow* part.
Even better:
banning #bigtechs from owning social media.
Social media developed by bigtechs is the real problem.

The imaging technique used here emulates old Kodak Aerochrome film stock. It’s not available anymore, but used to be a colour IR film, which mapped the IR on the blue channel, while remapping red and green to get this pink-foliage look. I do the same here!

in reply to Jana • • •There are some hardships though, since the camera now sees a lot more light (the full IR spectrum), but the light-meter cannot process that properly, auto-exposing is off by about 2 steps. Even worse, with the missing filters and the phase-detect diodes not being in that path anyways, the auto-focus is now off by a tiny bit. You can get used to it, but at first, I was just way off with my focus and exposure.
The resulting images are also very much discoloured, this is because the red and blue channels have to be swapped, which given that I shoot raw becomes annoying. I don't think there is a command line tool to switch two channels in a canon raw-file (.cr2), imagemagick will just invoke darktable.
Using darktable for development would be great, but I sadly have a bunch of bugs with it and my tool of choice is anyways DxO PhotoLab... which cannot swap colour channels -.-

TomKrajci 🇺🇦 🏳️🌈 🏳️⚧️ (Universeodon Social Media)FWIW, here are some near-IR shots I've taken with a camera that has all UV/IR filters removed...and the Bayer color array...so it's a monochrome camera...a poor person's version of a Leica.

I also have an IR LED array. A cheaper sort of phone camera or old vidicon "sees" with it easily. but almost useless for the Canon, which is good really.
The cheap phone "sees" the UV light very differently too!

Here are some options to get a dedicated IR (and even UV if you remove all the filters):

Or find a discarded point-and-shoot at a flea market and hack into it yourself. You can find how-to vid's on YouTube.
I have experimented a bit with portraiture in various bands using a full-spectrum camera. In near-IR everyone has pasty white skin. Think of the scenes in Dune 2.

If you shoot in near-UV, every freckle or other dark skin mark looks like a blotch of india ink. Folks can look 20 years older in near-UV.

Thanks for asking.
monochromeimaging.com/ did the conversion for me. I sent them a used Sony a6300 body.
They never told me how they did it, and I never asked...but my hunch is that they removed the sensor from the camera body and then heated it...just enough to soften the adhesive that held the Bayer filter in place, gently pried it off, and put the sensor back in the body with some spacers to change the sensor height. They had to do that because removing a glass filter out of the converging optical path shifts the resulting focal plane...so they set sensor height so that my manual lenses had the same focus setting...infinity focus setting remained the same after the conversion, give or take a few thousandths of an inch. Works for me. Your mileage may vary.

the correct way to removie it is to buy the dedicated hard-baked-photoresist remover from 3m, some horrbile concoction of solvents that you apply to the chip boiling hot
