Fusion Lab 1.0 RC4 · 25 August 2026
AI Background V2, NAFNet denoise and full-resolution editing.
RC4 advances Astro Background Extractor AI V2 and consolidates quality, performance and persistence across Astro Editor—from gradient correction and denoise to history, color and export.
Build 1.0.0.5
Global AI Background, vignetting and AI Denoise preferences are preserved when older projects are reopened instead of being overwritten by legacy project values.
V12 plus protected V13 Refine
The default pipeline uses V12 as Stage A and V13 Refine as a protected Stage B, with an automatic Stage A fallback if refinement fails.
NAFNet quality at source resolution
Dedicated strength, detail, nebula, star and color protections combine with NAFNet SIDD w32 for full-quality output.
Stable states keep source quality
With Safe Mode off, stabilized history states render at source resolution while lightweight proxies are limited to interactive dragging.
Configurable Sigma/MTF display
Linear FITS files open at a 10% / 3σ MTF Auto-Stretch by default, with a configurable 1%–50% target background.
More selective color protection
Stellar chromatic-aberration correction, Natural Astro Color and AI White Balance better protect nebulae, emission detail and highlights.
Choose first, render once
Export dialogs open immediately; full-resolution rendering begins only after the destination has been selected.

- RC4 Windows handoff prepared; the public Windows package remains RC3 until the new build is compiled, signed and published
RC2 · Build 3 — 30 July 2026
One Masks workspace across both editors
Astro Editor and Photo Editor now share the same masking workflow, visual language and local-editing logic.
HOLD / LOCKED means truly local.
Adjustments in the left column affect only the active selection. Clicking Done commits the complete masked edit as a single history state.
Shared Masks workflow
Graphics, mask layers, previews, Refine, Adjust and manual tools now behave consistently in Astro Editor and Photo Editor.
Every adjustment family
All Photo Editor adjustment families can be used with selections and masks. Switching or deleting a mask starts again from neutral local controls.
Faster manual painting
Brush+, Brush− and Eraser are smoother and accelerated on macOS and Windows, with precise local Undo/Redo from the very first click.
Cleaner, safer previews
Fixed zero-opacity overlays, painting beyond image bounds, Darken Sky Background, slider resets and ONNX/CoreML stability.
Unified navigation
Centered 1:1 zoom, Cmd/Ctrl + wheel, shared shortcuts, photographic guides and complete information bars across all four editors and viewers.
Refined interface
The Masks panel is cleaner and easier to scan, with unnecessary frames removed from slider rows.
Build 3 also improves work beyond the image edges, mask preview accuracy and local history reliability while keeping the editing pipeline non-destructive.
Fusion Lab 1.0 RC2
Everything added after RC1
RC2 expands the editing workflow, strengthens non-destructive project safety and improves AI, RAW, FITS and cross-platform reliability.
Unified Masks workspace
Shared Astro/Photo masking with layers, Refine, Adjust, previews, local history and accelerated manual brushes.
Star Effects Studio
Standalone Glow, diffraction-spike, Soft Flare and Ring Flare workflow with automatic or manual star selection and independent effect layers.
Astro Editor Base / RAW
RAW temperature and tint, exposure, contrast, highlights, shadows, whites, blacks, texture, clarity, dehaze, vibrance, saturation and HLVG.
Non-destructive Astro history
Visible future states, Undo/Redo and named snapshots now follow the Photo Editor model, with an isolated Starless baseline.
Safe Stars / Starless editing
Play, Edit and Finish behave as one transaction. Undo truly returns to the previous state, while Cancel never contaminates the image.
Editor autosave
Work is protected before a project is loaded, replaced or abandoned, reducing the risk of losing an active editing session.
AI Astro Blend Beta
Correct crop and canvas handling, more conservative registration, edge and star protection, halo suppression and photometric/chromatic matching.
Stronger RAW and color
As-shot metadata and white balance, highlight-safe AI White Balance, more robust temperature/tint and astro-safe handling of linear data.
11 languages
Switch language at runtime without disturbing the project. Learn, FAQ, tooltips and AIRI include broader coverage.
Cross-platform stability
CoreML CPU+GPU on Apple Silicon, ONNX CPU on Intel, DirectML on Windows, Unicode paths and more robust project saving.
Reliable FITS support
Correct Astro Editor loading and ABI-consistent CFITSIO headers and libraries strengthen scientific-format compatibility.
New in RC2
Star Effects Studio
Finish astronomical images with controlled, layered star effects—without leaving the Fusion Lab editing workflow.
Create Star Glow, diffraction spikes, Soft Flare and Ring Flare using automatic detection or precise manual star selection. Start with Essential controls, open Advanced parameters when needed, save presets and inspect the star mask or an Effects Only result in real time.

Meet AIRI · Web + Fusion Lab
Your assistant in Fusion Lab—and on the AstroPanel website
AIRI understands the AstroPanel ecosystem, the Fusion Lab workspace you are using and the processing decision in front of you.
Use it inside Fusion Lab 2026 RC4 for context-aware guidance, or open the same assistant from your AstroPanel account when you are away from the application. AIRI access is included with your Fusion Lab license.
Guidance built around the workflow in front of you
From Standard Calibration, Deep-Sky, Comet and Focus Stacking to Photo Editor, Astro Editor and AI Astro Blend, AIRI can explain controls, interpret visible issues and suggest the next useful check.
Understand context
Recognizes the active editor, workflow and available project context.
Analyze a preview
Examines an optional reduced, metadata-free preview after consent.
Choose the next step
Turns the current result into a clear sequence of checks.
Explain controls
Clarifies masks, stacking, color, export and Astro Blend parameters.
Show its sources
Links relevant documentation, guides, FAQs and release notes.
Use AIRI inside Fusion Lab 2026 RC4
Activate or verify your Fusion Lab license, open Settings → AIRI, select Cloud service and start a conversation. AIRI can receive the active workspace, selected language and relevant help context so its answers stay specific to your task.
Use AIRI on the AstroPanel website
Sign in with the AstroPanel account connected to your Fusion Lab purchase, open AIRI and start a new conversation. Your recent web conversations remain available in the AIRI workspace.
Optional image analysis, with explicit consent
When you attach an image, Fusion Lab or the browser prepares a reduced preview without metadata. The original file is never uploaded, the gateway does not retain the preview and the AI service key remains protected on the AstroPanel server.
Advice stays under your control
AIRI analyzes, explains and recommends; it does not apply edits to the image. You review every suggestion and decide what to change. If the cloud service is unavailable, Fusion Lab's local Learn, FAQ and tooltips remain available.
Purpose-built imaging intelligence
Two specialized image-processing AI engines
Alongside the AIRI assistant, Fusion Lab includes two different AI imaging engines, each designed for a specific astrophotography problem.
AI Background Extractor — integrated into Astro Editor
Estimate and remove uneven illumination, broad color casts and low-frequency gradients without placing a manual sample grid. Inspect the proposed background model before applying it, then continue with stretch, color, masks and star processing in the same workspace.
AI Strength, Structure Protection and residual-gradient controls keep the correction reviewable and help preserve stars, nebulae and faint astronomical structure. Processing runs locally, while Polynomial and RBF extraction remain available as classical alternatives.
AI Astro Blend Beta — tracked sky and foreground fusion
Persistent Sky and Ground layers inside Local Masking provide independent alignment, transform, feathering and edge controls plus a safer HOLD → Done workflow.
Sky/Ground selections, masks and transformations stay synchronized. Full-resolution 16-bit export, horizon protection, opacity, Adjust controls and complete Reset behavior are more reliable.
AI Background Extractor cleans and prepares the astronomical image; AI Astro Blend combines a finished sky with the landscape.
AI Background Extractor
Reveal the signal behind an uneven sky.
Remove broad gradients and unwanted color from astronomical images while keeping the correction visible, adjustable and under your control.
AI Background Extractor estimates the low-frequency background separately from the astronomical subject. It is designed for difficult illumination patterns such as vignetting, light-pollution gradients and chromatic contamination, with Structure Protection helping retain stars, nebulae and faint detail.
RC4 · AI Background V2
The default pipeline uses V12 as Stage A and protected V13 Refine as Stage B, with a safe Stage A fallback. V13 Global remains optional. Processing stays local, visible and reviewable inside Astro Editor.
Parameter scale comparison
Fusion AI Background V10 uses approximately 54 million trainable parameters. Across the model lineage, capacity expanded from 2 million parameters in V2 to 17 million in V5 and 54 million in V10, supporting progressively richer representations of spatial gradients, chromatic variation and astronomical structure.
Fusion AI Background V22M
Fusion AI Background V517M
Fusion AI Background V1054M
Inspect linear data clearly
STF applies an automatic Screen Transfer Function for display only. It reveals the background, faint signal and residual gradients without changing the underlying linear pixels — ideal for evaluating the extraction before committing to the next processing step.
Control the visible rendering
MTF provides a controlled Midtones Transfer Function with an adjustable target background and sigma range. Use it to compare versions consistently and export a stretched, presentation-ready rendition when a visible result is required.
Keep the scientific workflow intact
Background estimation and display stretching remain separate. Preserve or export the corrected linear master for continued scientific processing, and use STF or MTF only when you need a readable preview or a rendered output.
AI Background Extractor has been evaluated on held-out astronomical scenes across multiple gradient families. Results remain image-dependent; full-resolution visual inspection is always recommended before final export.
The complete toolkit
16 dedicated workflows
Open a category to explore the tools built for astrophotography, multi-exposure photography, editing and inspection.
Astrophotography
Standard Calibration
Import and classify Light, Dark, Flat and Bias frames. Inspect calibration masters, preflight Light-frame quality and stack with Mean, Median, Winsorized Sigma Clipping or Linear-Fit Clipping.
Quality weighting, Drizzle 2×, rejection-map export, adjustable sigma, stellar registration, RGB balance and linear 16-bit or 32-bit TIFF output are included.
Deep-Sky Stack
Calibrate optional Dark, Flat and Bias frames, align the Light sequence and combine it as LRGB, HOO, SHO/Hubble or RGB plus narrowband. Export 16-bit TIFF, 32-bit float TIFF or 32-bit float FITS.
Comet Processing
Calibrate the sequence, detect the comet nucleus and register Light frames on its motion. Choose Mean or Median integration while preserving chronological capture order.
Star Trails
Combine a fixed-camera sequence with Lighten/Maximum, Mean, Comet Trail or Reverse Comet Trail. Smooth tapering creates a controlled bright head and fading tail.
Star Effects Studio NEW
Create Glow, diffraction spikes, Soft Flare and Ring Flare with automatic/manual star selection, Essential and Advanced controls, presets, masks, Effects Only output and a real-time preview.
Multiple layers can use different stars and effects, with independent visibility, order and opacity.
AI Astro Blend BETA
Blend a tracked sky with a foreground at original resolution. Automatic sky segmentation uses an ONNX model with a classical fallback; registration supports translation, similarity, affine, homography or local mesh warp.
Refine paired control points, positioning and masks; match exposure, color, local contrast and noise; protect stars; suppress halos; and choose edge-aware or multiband blending. The Quality Map identifies seam risk, doubled stars, halos, uncertain registration and noise discontinuities.
AI Background Extractor
Estimate and remove uneven astronomical backgrounds with Structure Protection and an adjustable gradient-model preview. Use STF to inspect linear data without changing it, or MTF preview/export to create a controlled visible rendition. Polynomial and RBF extraction remain available as classical alternatives.
Astro Editor
Continue directly from calibration or stacking into a dedicated astrophotography editor with Base/RAW development, stretch, color calibration, masks, Starless processing, history and layered star effects.
Photography and multi-exposure
Silk / Long Exposure
Align and average a tripod sequence to smooth water and clouds at full resolution. Choose Mean for a natural long-exposure effect or Median to reduce transient elements.
Focus Stacking
Merge the sharpest local detail from frames focused at different distances—designed for macro, product and landscape sequences.
Mean Stack Denoise
Register repeated photographs of the same static scene and combine them with Mean or Median integration to reduce random noise.
Night Painting
Use Lighten/Maximum blending to combine the brightest pixels from multiple light-painting passes while preserving the fixed scene.
HDR
Align bracketed exposures through full-resolution exposure fusion. Select gentle, balanced or strong highlight recovery, work in 16-bit or 32-bit and start from 15 HDR looks.
N-HDR — Night Photography
Develop urban and suburban night brackets with dedicated highlight recovery, automatic exposure ordering and 32-bit tonal precision, then refine color casts, urban lights, structure, haze and gradients.
Panorama — Photomerge & Fusion Pano
Find overlaps, estimate camera geometry and blend full-resolution photographs. Use Auto, Perspective, Cylindrical, Spherical, Collage or Fusion Pano Multi-row projection with Astro, Terrestrial and multi-row profiles.
Inspect correspondences, add control points, remove outliers, preview seams, normalize exposure and color, apply final RGB balance and choose Safe, Bounding or No Crop. Auto-stretch affects the preview only—not linear output.
Photo Editor
Develop RAW photography with complete tonal and color controls, local retouching, luminosity masks, non-destructive history, snapshots and full-resolution professional export.
Editing and inspection
Two editors, built around the image
Photo Editor
A complete photographic development environment with real-time preview, non-destructive history and full-resolution export. It combines conventional RAW development, local retouching and dedicated tools for monochrome and urban night photography.
Core photographic development
- RAW controls: temperature, tint, exposure, contrast, highlights, shadows, whites, blacks, texture, clarity, dehaze, vibrance and saturation
- Tone Curve and per-color HSL controls
- Orton and Glow with independent intensity, radius and contrast
- Dodge, Burn, Water, Light Magic, Foliage and Atmosphere controls
- Multiscale luminance and color-noise reduction with structure and star protection

- Crop, straighten, spot heal, clone stamp, brush, text, white-balance sampler and composition grid
- Undo/redo history, named snapshots and interactive Before/After comparison
Black & White
A complete monochrome development section, not a simple desaturation switch. An eight-channel mixer controls how Reds, Oranges, Yellows, Greens, Cyans, Blues, Purples and Magentas translate into grayscale.
Refine the result with dedicated contrast, cool-to-warm toning and film grain. Natural, Portrait, Landscape and Dramatic Sky presets provide useful starting points while every channel remains adjustable.
N-HDR / Urban Night
Designed to finish night-photography brackets created by Fusion Lab's N-HDR merge, with targeted Yellow, Red and Magenta Cast controls. Urban Lights recovers color and detail in artificial lighting, Structure restores local definition, and Haze / Gradients controls atmospheric contamination and uneven illumination.
Unified Masks and targeted editing BUILD 3
Use luminosity ranges, AI Sky/Ground selections, manual Brush+, Brush− and Eraser tools, ranges and combinations inside the same Masks workspace shared with Astro Editor.
Refine a selection, preview its overlay, then open Adjust to apply any Photo Editor adjustment family locally. HOLD / LOCKED limits the left-column development controls to the active selection, and Done records the complete edit as one history state.

Image Viewer
Open supported photographic and scientific formats with metadata, zoom and inspection tools before choosing the next workflow.
Quality before rendering
Identify weak inputs before they damage the result
Light-frame Preflight
Analyze star count, FWHM, eccentricity, SNR, clipping, color casts and motion. Every frame receives a quality score and a conservative keep/reject recommendation.
Calibration Inspector
Inspect master Bias, Dark and Flat statistics, defective pixels, illumination, vignette maps, defect maps and compatibility warnings.
Panorama diagnostics
Validate overlap and geometry without composing the full panorama, with confidence, inliers, seams and corrective actions recorded in the diagnostic log.
Professional output
Ready for web, print or scientific processing
Export JPEG, PNG, 16-bit TIFF or 32-bit float TIFF. Resize to a target width, sharpen the output, position a PNG watermark, control JPEG quality or maximum file size, and convert to sRGB, Adobe RGB (1998), ProPhoto RGB or Display P3 with the ICC profile embedded.
Scientific workflows can remain linear; Deep-Sky also supports 32-bit float FITS.
Full resolution
Bounded previews, cancellable jobs and memory-aware execution keep large imaging projects under control. The persistent queue processes demanding jobs sequentially and safely restarts interrupted work.
Selected operations use Metal acceleration on supported Apple systems. Compatible AI models run through ONNX Runtime, with classical fallbacks where available.
