The whole process

Nine steps. In order. That’s the trick.

Astro processing isn’t hard — it’s just usually presented in the wrong order, all at once, in software built for experts. AstroWizard walks you through the same professional workflow one step at a time, with a live preview and an Undo for everything.

  1. Load your image
  2. Crop the edges
  3. Remove the gradient
  4. Balance the colour
  5. Sharpen
  6. Reduce noise
  7. The Big Stretch
  8. Make it beautiful
  9. Export & share

Downloads

Install in about a minute

AstroWizard is in open beta and isn’t code-signed yet, so your computer will act suspicious the first time. That’s normal for independent software — here’s exactly what to click. It only happens once.

Windows WINDOWS 10 / 11

Download for Windows

  1. Download AstroWizard-Windows.exe — nothing to install, it just runs.
  2. If a blue box says “Windows protected your PC”: click More info, then Run anyway.
  3. That’s it. Load an image and follow Step 1.

First-time setup · 2 minutes

Open ⚙️ Settings & Help and point AstroWizard at your AI tools — they usually live here:

GraXpert:
C:\Users\<you>\AppData\Local\Programs\GraXpert\GraXpert.exe

RC-Astro:
C:\Program Files\RC-Astro\CLI\rc-astro.exe

Then open GraXpert once on its own and run each tool — it downloads its AI models on first use.

Why the warning? Microsoft charges independent developers for a signing certificate; during the beta we skip it. The build on this page is always the official one.

macOS APPLE SILICON · ALL M-SERIES

Download for macOS

  1. Download AstroWizard-Mac.zip and double-click to unzip.
  2. First time only: right-click (or Control-click) AstroWizard → Open → Open.
  3. After that, open it normally like any app.

First-time setup · 2 minutes

Open ⚙️ Settings & Help and point AstroWizard at your AI tools:

GraXpert: just pick GraXpert.app in your Applications folder — AstroWizard finds the engine inside automatically.

RC-Astro: choose the rc-astro program from wherever its installer placed it.

Then open GraXpert once on its own and run each tool — it downloads its AI models on first use.

Why right-click? Apple’s yearly developer fee is skipped during the beta — right-click → Open is macOS’s official way of saying “I trust this one.”

Linux X86_64 · NEW

Download for Linux

  1. Download and extract: tar -xzf AstroWizard-Linux-x86_64.tar.gz (or right-click → Extract Here).
  2. Run AstroWizard/AstroWizard. Nothing to install.
  3. Something odd? Launch it from a terminal and paste what it prints into a YouTube comment, with your distro. That’s the report that gets it fixed.

First-time setup · 2 minutes

Open ⚙️ Settings & Help and point AstroWizard at your AI tools:

GraXpert: pick the .AppImage file itself (mark it executable first if needed).

RC-Astro: choose the rc-astro program from wherever its installer placed it. GPU acceleration on Linux currently needs NVIDIA; it runs on CPU otherwise.

Then open GraXpert once on its own and run each tool — it downloads its AI models on first use.

The newest build of the family — it compiles clean and boots clean, and Linux astro folk are hereby deputised as its test pilots. Expect rough edges; report them proudly.

The AI steps

Plays well with the professionals

For the heavy AI lifting, AstroWizard drives the same engines the experts use — point it at them once in Settings and the buttons light up.

FREE

GraXpert

Background gradient removal and AI denoising. Open GraXpert once after installing so it fetches its AI models — then AstroWizard takes it from there.

Quick answers

Before you ask…

The five questions that cover 90% of the comment section.

What files can I load?
Stacked FITS or TIFF from anything — Seestar, Dwarf, ASTAP, Siril, PixInsight, DeepSkyStacker. AstroWizard figures out the format quirks (bit depth, pixel range, bloated headers) automatically. Stack first, then bring the result here.
I clicked a GraXpert button and nothing happened.
Open GraXpert itself once and run Background Extraction and Denoising one time each — it downloads its AI models on first use. After that, AstroWizard’s buttons work every time. (Recent builds will tell you this right in the console.)
The RC-Astro steps are slow on my machine.
Update the CLI: open a terminal and run rc-astro update --install. A bug that made some images take minutes was fixed in July 2026 — both by RC-Astro and inside AstroWizard itself. Still slow? The in-app console will say why.
Is it really free?
Really free. Not a trial, not “free until it gets popular” — free is the plan. Development runs on goodwill: a tip jar and a Patreon below if it makes you smile, and buying RC-Astro tools through the affiliate links here or in the app supports it at no cost to you.
My antivirus / Mac says it’s from an unidentified developer.
That’s the missing code-signing certificate, not a threat — see the install steps above. Only download AstroWizard from this page or the links in Lukomatico’s own videos.

2026 · JULY 9

The big fix-everything build

PixInsight-stacked files no longer slow the AI tools to a crawl; ASTAP images no longer load pure white; colour pops are gentler with a new custom-strength dial; GraXpert problems now explain themselves in plain English.

2026 · JULY 8

Apple Silicon, natively

A true M-series Mac build — no Rosetta required. Plus honest stretch labels and better guidance on faint targets.

2026 · JULY 7

Curves, with colour targeting

A full curves editor that can aim at just the reds, blues, or any colour family — the most powerful tool in the app, for when you’re ready for it.
