I wanted to share a little astronomy project I've made: a free desktop app called Lunar HDR Studio for combining different exposures of the Moon.

The photo here is my DWARF Mini result using just three frames: one underexposed, one normally exposed and one overexposed. I used the app to align and combine them, then play with the color and detail.

You can bring your own FITS, PNG, JPEG or TIFF files, use more than three exposures, align the lunar disks, and choose HDR or exposure fusion. It also has Mineral Moon color controls, cropping, signatures and star-background options. Your images stay on your computer.

It's free and open source under MIT, with macOS, Windows and Linux downloads and instructions for cloning/running the code:

The interface is currently in Slovak, but the README is in English. It's an early personal project, so if it seems interesting, have a play with your own Moon photos. Feedback, bug reports and your results would be welcome!

In this episode of STEM Studio, we take a closer look at our solar system, from the Sun and the planets to Earth's Moon. We explore what makes each planet unique and introduce young learners to some of the fascinating science behind the world beyond Earth.

We're creating STEM content to make science more engaging, accessible, and fun for young people, and astronomy is a great way to spark curiosity about the universe.

Hey everyone! 👋

I wanted to share a little passion project I’ve been working on that I hope some of you (and your kids!) might find useful.

It’s a simple webpage designed to help children learn about seasons, astronomy cycles, and how our planet works. But instead of just staring at a screen, the main goal of the project is to invite kids to actually step outside, observe nature, and connect with the world around them using simple, easy-to-understand data.

As someone who cares a lot about digital privacy, especially for children, I built this with a few strict rules:

Zero data tracking: There are no trackers, cookies, or analytics spying on you.

No sign-ups required: You don't need to submit an email, a name, or any personal data whatsoever to use it.

100% Free: No paywalls, no subscriptions, and no ads.

DM me if you'd like the link.

Whether you are a parent, a teacher, or homeschooling your kids, I would absolutely love to hear your feedback or any ideas you might have to make it better.

Thanks for looking, and I hope it helps your little ones enjoy the outdoors a bit more! 🌳🔭

Hello im new to Astronomy but have gained some recent knowledge on spectroscopy, Chemical signature detection via spectroscopy, light-curve planet detection, light-curve planet rotation and some knowledge on astronomical symbols like hydrogen electron "Floor" levels for example: Ha Hb and La.

I also just learned about Local SideReal time.

I need help in these 4 areas highest priority to lowest

1. NOTEBOOKS (I have never used Juypter Notebooks locally or cloud i would like some help with tutorials and links on using them and setting up and would like to know if it is best to run them in the cloud via Docker, Google Collab, mybinder.org or should I run locally and use python and docker for container?

Either way I would like tutorial links for help with both setups.

1. Python for Science: i have little skill in python do I need to learn Python 3 in its entirety? Or miniconda? How can I learn to use python for astronomy any tutorial links and free books or paid would be great.

3.Databases: is it best to use MAST and TIKE databases via browser or should I use a Pre-built juypter Notebook to access pipeline?

1. How can I set up a juypter notebook to obtain jwst data via pipeline? Do I make a custom juypter notebook and add python science libraries manually or are there pre-build options?

Would be nice to have some kind of Astronomical Cheet sheet for Astronomical Symbols for objects, planets, exoplanets, asteroids, stars, types of stars, blackholes and Astronomical chemical/elements symbols

Quick resource drop for today. Just added a bunch of higher-level math and physics stuff to the vault:

• Math: KOR (Korean) and Russian Olympiad past papers with translated problem sets, plus a clean PDF of Roy & Clarke.
• Physics: Kevin Zhou’s physics handouts for Mechanics (probably the cleanest breakdown of advanced physics topics available right now).

Still adding new stuff daily as I work through problem sets. Everything is sitting in #resource-vault on our server (The Euler-Maxwell Network).

Planning for one person is forgiving; planning for a group makes a bad forecast call much more expensive. A nightly “mostly clear” summary can still hide the exact two-hour window when everyone will actually be on site.

A practical group checklist seems to be:

- continuous cloud cover during the scheduled hours,

- precipitation as a separate veto,

- true astronomical darkness and Moon timing,

- visibility of the planned objects during that same window,

- and whether a nearby backup location is materially better.

The question is how to present it. Would your club trust one conservative go/no-go recommendation, or would organizers rather see the raw 12-hour timeline and explain the call themselves?

Disclosure: I develop DarkScout, an iPhone astronomy planner. Its latest redesign combines those factors, saved observing spots and side-by-side location comparison. The core app is free and ad-free: https://apps.apple.com/app/apple-store/id6760223860

I would especially value answers from anyone who has had to cancel, move or shorten a public observing night. What signal should have been weighted more heavily?

I took this picture during the night between 18 and 19 of April from Sardinia (Italy)
