SyQon Studio 1.1 · Public Beta
One native environment. No hand-offs.
Local AIFloat64Non-destructive
01
One continuous workflow
Raw frames to final image
02
Local neural inference
Pixels stay on your workstation
03
Scientific foundations
WCS, Gaia XP and precision data
A continuous document
Keep the image, its layers and its processing history together.
SyQon Studio connects calibrated frames, stacking, masks, layers and colour-managed export in the same document instead of passing intermediate files between unrelated utilities.
One continuous workflow
Calibrate, stack, solve, restore, colour and finish without moving between disconnected applications.
Edit without fear
Layers, masks, previews, undo history and the SYQ Timeline keep every important decision visible and reversible.
AI that stays local
SyQon neural models run on your machine. Your astronomical images are not uploaded for inference.
Native image lab
Your image. Still yours at every step.
Build with layers. Protect with masks. Compare before and after. Move backwards through time without flattening your thinking.
SYQ Timeline
A visible processing graph that records the path from source to present.
Masks that belong to the workflow
Gradient, radial, brush, star and luminance-aware protection in context.
True layered composition
Opacity, blending, groups and reusable derived layers without losing the original.
New in Studio
Explore the depth. Build the bigger picture.
The latest Studio brings a calmer tools browser, a guided stacking workspace, Pano Studio and a spatial observatory into the same native image environment.
Spatial Observatory
Unfold a solved field into catalogue distances, explore stars and galaxies in 3D, select an object to orbit around it and compare estimated separations.
Sky annotations
Explore catalogue names and celestial coordinates over a solved image. WCS-aware overlays follow the astronomical field rather than becoming permanent image pixels.
Guided stacking
Move from frames to method and output in a focused three-step workspace, with Smart Telescope and Advanced paths, calibration groups and frame review.
Pano Studio
Bring overlapping panels into a dedicated workspace for alignment, control points, masks, composition preview and final rendering.
Share the spatial view
Export the scene as PNG, PDF or MP4 with the Earth as the observation origin. Choose Landscape, Vertical or Square video framing; every export carries the Studio signature.
Interactive scripting
Launch the focused model editor with -gui: ROI, model intensity, switchable Autostretch and Done return an image to the calling script in its original container format.
Spatial Observatory
Your galaxy field, seen in depth.
M106 opens a new way to explore the observed field: physical coordinates, published distances and an object inspector. Distances are catalogue estimates; a catalogue match is not confirmation of an image detection.
Names, coordinates and context
Read the sky over your own image.
Pano Studio
A dedicated workspace for overlapping panels.
Inspect sources, refine alignment and preview a composition before rendering. This demonstration uses overlapping crops of the supplied M106 master, not separate observations.

The complete image lab
Twelve disciplines. One visual language.
Every stage lives inside the same document system. You can move from measurement to creative finishing without exporting intermediate files or rebuilding context in another application.
01
Calibration masters
Bias, dark, flat and dark-flat workflows with reusable masters and traceable acquisition groups.
02
Subframe analysis
Inspect FWHM, eccentricity, background, noise, quality, star count and integration weight before stacking.
03
Registration & stacking
Robust star registration, rejection, drizzle, weighted integration and resumable processing sessions.
04
Mosaic Studio
Global overlap optimisation, common geometry, multi-panel integration and coverage-aware final canvases.
05
Local plate solving
ASTAP solving and WCS metadata work locally with managed high-density astronomical catalogues.
06
Scientific colour
Gaia XP spectrophotometric calibration, channel composition and colour-managed display and export.
07
Layered image lab
Pixel, component, channel and mask layers with groups, opacity, blending and independent visibility.
08
Precision masks
Brush, gradient, radial, range, luminance and star masks designed directly over the image.
09
Processing components
A coherent catalogue for stretch, colour, restoration, gradients, structure, stars and finishing.
10
Recoverable history
Undo, comparison states and the SYQ graph preserve intent while you explore alternative processing paths.
11
Faithful output
Scientific linear data or presentation-ready imagery with ICC-aware sRGB conversion and controlled dithering.
12
Managed delivery
The application, neural weights and catalogues update independently, securely and only when required.
Stacking Studio
From every exposure.
One measurable master.
A complete scientific preprocessing and integration environment for single-filter sessions, multi-band acquisitions, wide-field mosaics and moving targets.
01
Organise acquisitions
Build classic, multi-acquisition or mosaic sessions. Keep lights and calibration data separated by acquisition and filter.
02
Calibrate at source precision
Generate bias, dark, flat and dark-flat masters; optimise dark scaling; correct pedestals, overscan and defective pixels.
03
Measure every subframe
Analyse stellar FWHM, eccentricity, noise, background, detected stars and relative quality before committing to integration.
04
Register real geometry
Use robust multiscale alignment or blind SIFT/RANSAC projective registration for rotation, scale and perspective differences.
05
Normalise & reject
Match local backgrounds and optional local photometric gain, then reject outliers with the statistical model appropriate to the dataset.
06
Integrate & publish
Produce the master, coverage and rejection maps together with a complete JSON processing manifest and diagnostic report.
Integration laboratory
Rejection shaped around the data—not a single black box.
01Studentized sigma clipping
02Winsorized sigma clamp
03Linear-fit clipping
04Generalized ESD
05Percentile clipping
06Min / max rejection
07Large-scale rejection
08Weighted mean
Choose point-source SNR, stellar signal / PSF or inverse-noise-variance weighting. Low and high thresholds remain explicit, reviewable parameters.
Drizzle engine
6×maximum sampling
Native, 2×, 4× and 6× output sampling with controllable pixel fraction. Point drops remain available for densely dithered data.
CFA drizzle
Integrates real Bayer sensor samples without pre-integration interpolation
Coverage-aware
Tracks effective sample support and exposes uneven or missing coverage
No hidden denoise
Sampling changes remain separate from restoration and finishing
Subframe diagnostics
Decide with evidence before integration begins.
Analyse the complete session, review the diagnostic grid and plot, disable weak frames or define objective quality limits. The final weight and status remain visible and exportable.

Final integration contribution
Mosaic Studio
Plan the whole sky before integrating a single panel.
All filters share one planned canvas, origin and sampling. Every matchable overlap contributes to global geometry optimisation while the selected reference remains fixed.
- Automatic reference WCS, TAN, SIN and ARC celestial projections
- Robust global optimisation across panel overlaps
- Local background and constrained photometric gain normalisation
- Configurable overlap feathering and optional distortion correction
- Disconnected panels stop publication instead of inventing geometry
- Uncovered sky remains NaN with zero coverage—never synthetic signal
Verified checkpoints
Retain decoded frames and completed tiles, then resume a saved session after restarting Studio.
Memory-aware execution
Choose the working-memory budget; large integrations stream data and stop cleanly when the plan cannot fit.
Publish with provenance
Save Float64 linear masters, coverage and rejection maps, mosaic geometry and a versioned processing manifest.
Neural instruments
Specialised models, available inside the same workspace.
No scripts to move, no environments to maintain. Professional neural models* become native tools inside the same workspace and run locally through the integrated inference engine.
Local inference
Star separation
Axiom V3
A clean structural split for independent stellar and deep-sky processing.
Local inference
Neural restoration
DeepPrism V2
Essential, Advanced, Ultra and workstation-grade Max profiles in one local model family.
Local inference
Deconvolution
Parallax
Recover compact structure and correct optical softness through local inference.
Local inference
Gradient removal
Deep Gradient
Model-assisted background correction for complex wide-field illumination.
* Pro neural models are paid, optional add-ons. They are not required to use SyQon Studio.
SyQon Neural Suite
All three models. One Neural Suite.
Axiom V3, DeepPrism V2 and Parallax. Universal licence for €187 instead of €211.
Beyond the Studio interface
The same local engine.
Inside your workflow.
SyQon Studio includes a headless command-line interface for local, automated inference. Use it from external scripts and compatible applications without importing model weights or sending pixels to a cloud service.
Explore the CLI integration guideIncluded with Studio
Compatible automation hosts
PixInsight, Siril, SETI Astro—and anything that can call a local CLI.
Launch the SyQon CLI from process containers, scripts, batch workflows or your own application. Inputs and outputs remain ordinary astronomical image files, while Studio manages authentication, model entitlement, runtime assets, tiling and reconstruction.
Local by design
The host passes file paths and options; inference remains on the workstation.
One model registry
Free and licensed models use stable public identifiers—not private ONNX filenames.
Built for automation
Machine-readable progress, exit codes, cancellation and application handoff are part of the contract.
Compatibility refers to scripted or external-process invocation of the SyQon CLI. Product names belong to their respective owners; no native plug-in or official endorsement is implied unless explicitly stated.
From photons to image
A complete path, built in.
01
Calibrate
Bias, dark and flat masters, cosmetic correction and camera-aware preprocessing.
02
Register & stack
Quality analysis, robust alignment, rejection, drizzle and resumable integration.
03
Solve & colour
Local astrometry, Gaia XP colour calibration and WCS-aware tools.
04
Restore
Neural separation, deconvolution, denoising and multiscale structure control.
05
Finish & export
Layered colour work, display transforms and faithful scientific or presentation exports.
Scientific core
Creative freedom, built on measurable sky.
Studio treats astrometry, spectral references, acquisition provenance and image geometry as part of the image—not as disposable setup steps.
Dense local catalogues
Gaia and ASTAP resources are securely managed outside the application, updated only when their identity changes.
Provenance that survives
Stacking manifests retain accepted frames, rejection, gains, transforms, residuals and processing settings.
Geometry before aesthetics
Coverage, NaN regions, WCS and common mosaic coordinates remain explicit throughout the workflow.
Under the glass
Simple on the surface. Serious underneath.
Studio is designed for visual clarity without hiding the engineering: precision buffers, deterministic processing, hardware-aware inference and recoverable project state.
