AstroGraph – iOS Astronomical Image Analysis App
AstroGraph is an iOS application designed for astrophotography image analysis and pixel-level exploration of astronomical images captured through smartphones and telescope optical systems. The app enables users to process, visualise, and interpret celestial images directly on iPhone and iPad using advanced image analysis tools.
AstroGraph is intended for educational, research-support, and observational astronomy workflows, allowing users to extract meaningful visual and quantitative information from astrophotographic data.
*Key Features

Photon percentage estimation from RGB distribution
Surface brightness mapping for extended objects
*Celestial Signal Analysis
Pixel-level decomposition of astronomical images
Detection of:
Nebula-like emission regions
Stellar field components
Galaxy structural patterns
Signal classification (Low / Medium / High intensity levels)
*Morphology and Structural Mapping
Visual identification of structural features in images
Detection of:
Spiral-like galaxy patterns
Star clusters
Emission regions and brightness gradients
*Region of Interest (ROI) Analysis
Select areas using touch or drag gestures
Compute aggregated RGB and signal properties
Compare multiple regions within a single image
Store last selected region for continued analysis
*Image Processing Tools
Brightness correction filter
Surface brightness mapping
Emission proxy visualisation
Extinction and optical depth estimation
Transmission mapping
*Reset and Control Functions
Reset all analysis values and overlays
Clear selected regions instantly
Restore original image state for re-analysis
*How AstroGraph Works
AstroGraph processes images at pixel level using RGB-based decomposition and mathematical modelling to estimate brightness distribution, structural variation, and signal classification across astronomical images. The system is designed to support real-time observational interpretation during telescope imaging sessions.
*Important Notice
AstroGraph is an analytical and educational tool. Results are based on image processing algorithms and should be interpreted as observational estimates rather than absolute astronomical measurements. For scientific-grade research, results should be validated with professional astronomical instrumentation.
*Compatibility
Designed for iPhone and iPad devices running modern iOS versions.
