Suspiciously honest sky notes

A less lying planetarium

Trying very hard not to exaggerate.

Fresh from the telescopes

Stars, photos, and the database.

This is where I share night sky I saw. Nebulae, galaxies, and stars.

Billons of stars are from European Space Agency GAIA project

What is real here? Are these photos real?

Yes, I took them myself. Stars are took by ESA.

Why call it “less lying” instead of “honest”?

Every planetarium has to lie. This one does too, but here, the stars are shown using real scientific data in your browser, not just painted (from assets).

It’s slow

The data server is actually in my house, so everything depends on my home internet upload speed. Also, I’m a software engineer who forgot graphics long time ago.

It’s up to your GPU too!

It works like a small telescope simulator: your computer/phone’s graphics card is always recalculating what you see, constantly updating what you “should” see based on the data.

Are the photo positions accurate?

Yes, each photo is placed at its exact/computed sky coordinates.

How long did it take?

A year. Then three months with LLM.

Actually, can I include years of learning astrophotography too?

The map keeps receipts

The pictures know where they live.

Click an image and the celestial sphere swings toward its address. No mystical hand-waving here, just right ascension and declination doing the paperwork.
