It throws out the bad frames

Clouds, satellite trails, dew on the lens — bad subs get dropped automatically, and the report tells you which files and why.

It develops the image for you

Star-aware AI enhancement measures YOUR image and picks the recipe: noise smoothing, gradient flattening, star handling. Sliders are there if you want them — not homework.

Watch it build, live

Point it at your capture folder and watch the image deepen sub by sub while the telescope is still outside.

Runs on your own PC. Your data never leaves your desk. Buy it once — no subscription required.

Questions, answered

A Windows PC and a folder of FITS files from any telescope or camera. Smart scopes, guided rigs, or a camera on a tripod.

Yes — MEBA is in open beta, free while we polish it with real users' skies. After the beta it moves to early access at a discounted price, then a one-time purchase at launch (no subscription — you buy it, you own it). Beta testers hear about early-access pricing first.

Join the Discord (mebastacker.com/discord) — bug reports, feedback, and a channel to show off your stacks. You can also just use the thumbs up/down buttons in the app after each stack.

Beta builds have an expiry date baked in — the app tells you well in advance and updates itself in one click. Your images, stacks, and results always stay yours and stay accessible, expiry or not.

Officially: Mike's Easy Button Astrophotography Stacker. The whole app is built around one idea — you push the button, it makes the decisions. (A friend insists it's 'Michael's Epic Bad Ass Stacker.' We don't correct him.)
