Lembrete para que o restauro da #noite em Portugal seja incluído no Plano Nacional de Restauro. No documento agregado em discussão pública (até 19/8 -link para participação no texto), omitiu-se o tema; nos poucos relatórios técnicos em que surge, a formulação é totalmente ineficaz. #poluiçãoluminosa

4h now. Didn't push the stretching and colour as far as I could have. Something's gone wrong with the flats. I have been using a drawing screen as a makeshift flat screen. It works well but for the Askar 60F I generally put a white t-shirt in front of it before taking the flats (1/2)

Our Icelandic/Norwegian/Swedish/Finnish #IAU project "Nordic Darkness Awareness", has been selected to proceed to Phase II! The committee describes our idea as "A great proposal. This is very important work!" among other things. Now we'll just have to impress them during the next round as well. ✨🔭
AstroBin's Image of the Day: "Sh2-136 - The Ghost Nebula" by Robert Eder www.astrobin.com/30jktm/ #astrophotography
Here is roughly 8h of luminance data (over three nights this past week) with this #astrophotography of NGC2655 done without any rejection algorithm. There's a slight satellite trail pollution don't you think? This is sad, knowing that some companies are willing to make things even worse 😢.
West of @science.esa.int's space astronomy center #ESAC Spain's major #wildfires are raging, threatening towns and people's livelihood. Fires are out of control and further development will depend on weather. We hope that people stay safe and hope #Spain gets all the support it needs. 🔭
"Childcare? I feel great about it. Three days a week, I leave my child with strangers, pay them as much as my mortgage, and resist the urge to call every 15 minutes to see if my baby has rolled over for the first time and I missed it because I was watching a compliance webinar."

João Calhau@astrocalhau.bsky.social · 2w agoFirst two hours of the Andromeda Galaxy, M31, this year. Taken last night. The moon is getting kind of bright so I'm not unhappy at all with how it came out. If all goes well I'll be on holiday next month and I'll be able to add more hours to it.

The pic posted *is from the CDC website*, and shows just how bad things are now. There have been numerous and huge studies that conclusively show no link between vaccines and autisim. None. See for example www.amsterdamumc.org/en/research/...
Waldo Jaquith@waldo.net · 2w agoThe claim “RFK Jr. does not fuck chickens” is not an evidence-based claim because studies have not ruled out the possibility that RFK Jr. fucks chickens.

95% of recent Astrobin's image of the day picks seem to be taken from remote observatories with near professional equipment. I don't have a stake in it (I don't have an account on Astrobin and my images wouldn't make anyways), but it feels like it's not about amateur astrophotography anymore...
To those at the #NAM2026 plenary hearing things like “and that’s when I knew we were going to win [over other survey teams]”, know that you can do brilliant science in a collaborative and mutually encouraging way, rather than treating everyone else as a competitor. We decide/set our culture. 🔭
Me playing Elden Ring for the first time and meeting the Tree Sentinel.
Google tells me this is a Protambulyx strigilis, or the Streaked Sphinx moth. Which is surprising because it also tells me they're from the Americas. But is here on my window anyway. It looks a bit battered but we're not disturbing it in the hope it makes it to night time and goes to its life.
Lotteries are odd at astronomical societies. I have almost exactly the same story at the same age with my society….
25 years ago, a middle aged man brought is young son (12) to a meeting of the Portuguese amateur astronomy association. It was the first time the boy met anyone interested in astronomy. The first time where actual doctors (PhD) interacted with them (1/10)
I'm consumed be "externalities" that private companies quietly distribute across humanity for profit while preaching narratives about "progress". Add in "Shifting Baseline Syndrome" and most people don't notice what's happening until it is too late. Some underlying verifiable facts 👇 ✨🔭🧪
Fair. Guess the future of movies is that I'll stop watching them. And there's nothing George Lucas can do about it. If "art" stops being made by people, it is no longer "art". There is no message, no idea, no point in appreciating it.
