BiggSky — astrophotography image processing software
What would you like to do?
Three routes into BiggSky, depending on where you are.
I'm new to BiggSky
Install it, get a licence and process your first image. The Quick Start takes about fifteen minutes.
Show me what it can do
Real results from real imagers — several of them AstroBin Images of the Day. See the gallery.
Give me the software
Version … for Windows, macOS and Linux. Free for 30 days.
Calibrate. Stack. Enhance. Publish.
The whole pipeline in one application — from raw frames to a finished image, without shuttling files between four different programs.
11 seconds · raw frames to finished image
Calibrate
Apply darks, flats and bias to your raw frames. Camera RAW, FITS, XISF, SER and TIFF all read natively.
Stack
Automatic frame grading and alignment. No alignment points to place, and no grid artefacts from drizzle.
Enhance
Blind deconvolution measures the blur in your own data and removes it. No reference star, no wavelet guesswork.
Publish
Colourise, crop and export at 8, 16 or 32 bits — or hand the result to your usual finishing tool.
Built around the blur, not around presets
BiggSky measures the optical and atmospheric degradation in each image and reverses it mathematically. Nothing is invented and nothing is hallucinated.
Automatic PSF estimation
Blind deconvolution derives the Point Spread Function from the image itself. You do not need a reference star, and you do not need to guess a radius.
Tiled processing
Seeing varies across a large lunar or solar frame. BiggSky splits the field into tiles and solves each one separately, then blends them seamlessly.
Clean stacks, fewer artefacts
High-frequency ringing and drizzle grid patterns are suppressed at the stacking stage — which is exactly what lets the deconvolution go further.
Batch it overnight
Queue a night's worth of SER or AVI captures and let BiggSky stack, crop and deconvolve them unattended. Review the results in the morning.
The same frame, before and after
Drag the handle. Everything on the right was already in your data — deconvolution recovers it, it does not invent it.
Processed with BiggSky
Work from the BiggSky community, including several AstroBin Images of the Day.

Runs about an hour. If you want the short version, the Quick Start guide covers the same ground in writing.
Windows, macOS and Linux
One application, built for each platform. Apple Silicon is a native build, not translated through Rosetta.
Windows
Windows 10 and 11.
64-bitMac — Apple Silicon
A native M-series build, not Rosetta.
arm64Mac — Intel
For Intel-based Macs.
x86-64Linux
64-bit Intel and AMD.
x86-64NVIDIA GPU acceleration on Windows
An NVIDIA card cuts processing time substantially — anything from Kepler (2013) onwards, which is most cards still in use.
There is a separate Windows build for Blackwell, the RTX 50-series, so the newest hardware is properly supported rather than merely tolerated.
Where GPU support stands
- Windows — NVIDIA, Compute Capability 3.5 and up. RTX 50-series needs the separate Blackwell build.
- Linux — not tested. It may work; we have not verified it, so we do not claim it.
- macOS — no GPU acceleration. Processing runs on the CPU.
- SSE Lite — no GPU acceleration. Same results, more slowly.
Developed on a 2008 workstation with a GTX 780 Ti. Yours is almost certainly faster.
