Mi presento: mi chiamo Stefano e sono uno sviluppatore amatoriale. Faccio astrofotografia da un po' di tempo ad un certo punto, stanco di lottare più con la tecnologia che con il cielo, ho provato a mettere tutto dentro un iPhone.

È nata così AstroStackerPro. L'app scatta tante foto brevi della stessa porzione di cielo, le allinea e le somma in un'unica immagine, facendo emergere stelle deboli, nebulose e la Via Lattea dal rumore. Sono onesto la foto è ancora grezza c'è tanto da migliorare ma per essere stata fatta con un telefono in centro città, quindi con inquinamento luminoso e condizioni non perfette è già qualcosa.

Long-time lurker, first real post. Hoping the mods give me a pass for self-promo because I think this community is exactly who I need to hear from.

After years of doing astro the conventional way — Windows laptops on the balcony that kept crashing, dedicated cameras with driver problems, endless cable management — I decided to find out whether modern iPhones could actually do live-stacking natively. Turns out they can, more or less. So I spent the past year building it.

AstroStackerPro: real-time live stacking entirely on-device, up to ~600 frames per session, IMU-based derotation using the gyroscope for untracked long integrations, on-board editor with denoise (AI, on-device), sharpen, light-pollution removal, and exports to FITS for those of you who want to take the stack into PixInsight or Siril.

Privacy: 100% on-device, no cloud, no analytics, no account.

Requirements: iPhone 11 or later, recent iOS.

Public TestFlight beta is open. One-person project, v1.0.1, definitely rough in places, and I am genuinely at the stage where real users finding the things I missed is more valuable than gold to me. So please be hard on it.

Honest caveat: for certain targets (deep sky, high magnification) you'll still want a tripod, a star tracker, or a dedicated iPhone telephoto — but I'm actively pushing to minimize the extra gear needed.

Best channel for detailed feedback is email at astrostackerpro@icloud.com, I reply individually.

Clear skies.

A while back, after yet another night on the balcony wrestling with Windows crashes, Mac drivers that wouldn't cooperate, and a prehistoric astro camera, I decided enough was enough. I built an iPhone app that does live-stacking astrophotography natively — no extra hardware, no laptop, just the phone.

It's called AstroStackerPro. You shoot a sequence of long exposures, watch the stack build up frame by frame on screen, and the Milky Way slowly emerges from the noise. Designed to be usable even if you're not an astronomer or a pro photographer. Nothing leaves the phone — no cloud, no account, no analytics.

Public TestFlight beta is open right now (v1.0.1). One-person project, so it definitely has rough edges here and there. iPhone only for the moment — if this gets traction I'm seriously considering an Android port.

Honest caveat: for some targets you'll still want a tripod, a star tracker, or a dedicated iPhone telephoto lens — but I'm actively working to minimize the extra gear you need.

If you give it a shot, real feedback at this stage is the best gift you can give me. Brutal is fine, just go easy 🙏 — best is email at astrostackerpro@icloud.com, I personally read and reply to every one.
