YOUR STACK, PROCESSED.
IN UNDER 2 MINUTES.
Upload your stacked FITS or TIFF. A 16-step processing pipeline handles background extraction, noise reduction, star separation, and color calibration — so you get a clean, ready-to-refine result without the hours of manual work.
See the Difference
Drag to compare: your raw stacked file vs. the processed result. Same data, faster workflow.
Upload. Process. Refine. Export.
No software to install. No GPU required. Processing runs on our servers.
Upload Your Stack
Drop your stacked FITS, TIFF, PNG, or JPG. Compatible with any telescope and stacking software.
Automated Processing
16 steps run on our servers: background extraction, star separation, noise reduction, color calibration, HDR merge, and more. ~2 minutes.
Review, Refine, Export
Preview your result. Fine-tune in the built-in editor — exposure, curves, selective color, crop. Export in TIFF 16-bit, PNG, or JPEG.
Upload. Process. Refine. Export.
What traditionally takes 1–2 hours of manual work, our pipeline completes in under 2 minutes. From background extraction to final export — automated, but always under your control.
16-Step Processing Pipeline
Upload your FITS or TIFF. Background extraction, gradient removal, star separation, HDR merge, color calibration — 16 steps, fully automated.
Deep Noise Reduction
Deep denoising trained on real astrophotography data. Cleaner images without losing nebula detail.
Star Separation & Control
Separate stars from nebulosity automatically. Adjust star size independently from your deep-sky objects.
Light Pollution Removal
Gradient and sky glow extraction — even from Bortle 7+ skies. Applied automatically.
Adaptive Auto-Stretch
Optimized stretch profiles for linear data. Adapted for Newton, refractor, smart telescopes, and any optical setup.
Real-Time Editor
15+ adjustments with instant preview. Works on processed results or any photo you upload.
Advanced Color Grading
Selective color on 8 hue ranges, stackable curves, vibrance. Professional-grade color control.
True 16-bit Pipeline
16-bit from import to export. FITS, TIFF, PNG — no banding, no compression, maximum dynamic range.

What our astrophotographers say
From beginners to experienced imagers, they use Cosmos Darkroom daily.
“I used to spend 3 hours in Siril for each image. Now I upload my FITS, wait 90 seconds, and the result is honestly better than what I was doing manually. Game changer.”
Marc D.
Seestar S50
“As a beginner, I was completely lost with PixInsight. Cosmos Darkroom gave me gallery-worthy results on my very first try. The AI noise reduction is incredible.”
Sarah K.
Vaonis Vespera II
“The 16-step pipeline handles everything I used to do manually — gradient removal, star control, color calibration. And the results are consistent every single time.”
Thomas R.
DWARFLAB Dwarf 3
“I was skeptical about AI processing, but the detail it pulls from my Newton images is stunning. The star separation alone saves me hours of work in Photoshop.”
