A general-purpose image preprocessing tool for astrophotography.
Capture One Pro scripts: temporal stacking, film grain, spectral film development with paper grades, zone map, median contrast, parametric curve, darkroom test strip and a report on which photos you keep. English and Spanish.
🔭🪐☄️ Reproducible, scriptable stacking pipeline for DWARF 3 smart telescope FITS data with transparent frame selection, registration, and science-grade linear outputs.
Free lunar & planetary image stacker for lucky imaging (SER), running natively on Windows, macOS & Linux with an English / Traditional Chinese UI. Familiar workflow if you've used AutoStakkert or RegiStax. Downloads here; source maintained privately.
Astro Image stacker (expecially for moon shots)
Aester · 星野与银河摄影自动后期 / Free star-field and Milky Way photo processing for Windows
Averaging is a simple python program to average a stack of images and reduce random noise
Astrophotography processing tools
End-to-end astrophotography workstation: plan the night, drive the mount/camera/filter wheel, then auto-sort, calibrate, stack and finish the captures — deep-sky, planetary, solar, eclipse, comet, mosaic and Milky Way panorama modes, mono or one-shot colour. Go engine + Vue UI driving Siril and GIMP.
Safe, resumable, RAW-first CLI for processing large star-trail photo sequences on macOS with auditable analysis, validated 16-bit TIFF development, human review, and streaming maximum stacking.
Point your iPhone at the real sky and understand it — then capture it. Open-source native iOS AR sky identifier + tripod night camera + AI photo editor + Celestron control. On-device, offline, all-custom Swift.
Free, open-source GPU astrophotography processing for Windows, Linux & macOS: a guided PixInsight/Siril alternative for calibration, stacking, denoising and more (alpha).
Open-source lucky imaging suite for planetary, lunar & solar astrophotography. Preprocess (PIPP-style), stack & wavelet-sharpen seeing-limited video into sharp images. Cross-platform Python, GPU-accelerated on Apple Silicon.
Free, open-source astrophotography stacker for the Celestron Origin, ZWO Seestar S50/S50 Pro and other colour cameras
End-to-end astrophotography suite — stack, stretch, develop, 3D fly-through video, and Sun & Moon lucky imaging. Native macOS (Apple Silicon) & Windows apps; source-available, free for non-commercial use.
Stack lightning photos in the browser. Layer blending, hand painted masks, snapping and PNG export. One self contained HTML file, nothing uploaded.
USB microscope capture for Linux: live enhancement, frame stacking, and measurement for UVC cameras
One-click lunar eclipse RAW stacking for any camera (Canon/Nikon/Sony/Fuji/DNG...): frame rejection, phase grouping, HDR-aware stacking, sliver rescue, PixInsight/Photoshop automation, phone composites, plus a Claude Code skill
Fast, GPU-accelerated planetary lucky-imaging stacker and sharpener for Windows, macOS and Linux. Published mirror of an internally developed project. Bug reports and feature requests welcome as issues; pull requests are not being accepted at the moment.
