Your Raw Sky, Understood.
Store, Plate Solve & Cloud-Stack Your FITS Data.
Replace hard drive graveyards and manual folder digging. Dynamic FITS metadata queries, sub-second WebGL auto-stretching, automated astrometric plate solving, and Siril-powered cloud stacking — directly in your browser.
Have a FITS file on your machine?
Test our client-side WebGL engine right now. Drag and drop any .fits subframe to stretch, inspect FITS headers, and pan in real time — 100% processed in your browser, zero upload to our servers.

Standard hard drives and generic cloud storage treat raw astronomy data as opaque binary files. Nyxaion understands the astronomical universe inside your headers.
External Hard Drives
- Silent disk drive failures with no automated redundancy
- Messy nested folder trees across multiple physical drives
- 45 minutes of searching to find last year's darks and flats
- Zero mobile access when imaging at remote dark-sky sites
Google Drive / Dropbox
- Blind to FITS headers (EXPTIME, FILTER, RA/DEC ignored)
- No non-destructive stretching or in-browser previewing
- Duplicating files into folders doubles your storage costs
- Zero plate solving, stacking, or calibration matching
Nyxaion Cloud OS
- Bit-for-bit lossless raw FITS cloud archive
- Dynamic project queries by target, filter, and coordinates
- Instant WebGL stretching & real-time color balancing
- Siril-powered cloud stacking without cooking your computer
Engineered for Astronomy Workflows
Everything you need to organize hundreds of gigabytes of deep-sky data, verify subframe quality, and produce publication-grade master stacks.
Dynamic Projects: Query The Sky
Never manually copy raw files into folders again. Define declarative queries like FILTER = 'Ha' AND OBJECT = 'Pacman Nebula'. As you capture and upload new subframes across months or seasons, your projects automatically aggregate matching frames without duplicating storage.
Interactive WebGL FITS Viewer
Open multi-gigabyte 16-bit and 32-bit FITS images in milliseconds. Non-destructive MTF, Arcsinh, and Log auto-stretching, real-time RGB color balancing, deep sub-pixel zoom, pan, and complete FITS header inspection directly in your browser.
Siril-Powered Cloud Stacking
Don't let multi-hour subframe registration tie up your local machine. Offload OSC debayering, multi-channel monochrome alignment, calibration frame auto-matching (darks, flats, bias), and multi-panel mosaic stitching to high-powered cloud worker clusters.
Automated Astrometry Plate Solving
Blind plate-solving powered by Astrometry.net and local ASTAP fallbacks. Every subframe or stacked composite can instantly reveal its true celestial coordinates, field rotation, and pixel scale with visual field-of-view overlays.
Predictable, Transparent Pricing
Start free forever on the Nebula tier. Scale up your storage, solving allotment, and cloud stacking as your telescope rig grows.
