A calmer, cleaner redesign with light and dark themes. New target presets for the Moon, planets, deep sky and the Sun (solar filter required). Folder batches run in the background with progress and resume safely if interrupted. Before/after compare slider, a new Settings screen, and an optional one-time Remove ads purchase.
Sharpen and deblur photos with 5 scientific algorithms. Presets and batch.
GalileoSharp brings scientific image-sharpening algorithms to your phone. Choose from five methods used in astronomy and image processing, tune every parameter with a live preview, and compare before and after with a wipe slider. Five sharpening algorithms • Unsharp Mask - amount, radius, threshold and multi-pass blur, with luminance-only mode and highlight protection • Laplacian - 4-connected, 8-connected or Difference of Gaussians (DoG) kernels, with a noise gate • Fourier (frequency domain) - Ideal, Gaussian or Butterworth filters with adjustable cutoff radius and filter order • Richardson-Lucy deconvolution - the iterative method used to restore early Hubble Space Telescope images; choose a Gaussian, Disk or Motion point spread function • Wavelet (multiscale) - separate boosts for fine detail, mid frequencies and coarse structure Target presets Start from a preset for the Moon, Planets, Deep sky or the Sun. The Sun preset carries a clear safety note: only photograph the Sun through a proper solar filter, because looking at it without one can permanently damage your eyes and equipment. Features • Before/after wipe slider on the parameter and compare screens: drag or tap to compare • Batch mode - sharpen a whole folder of images with the same settings. Batches run in the background with a progress notification you can cancel, and pick up where they left off if interrupted. • Saves full-resolution results to your Downloads folder • Works offline - your photos are processed on the device and never uploaded • Calm Material 3 design in light and dark Good for astrophotography, planetary and lunar images, old photo restoration, landscapes and scientific imaging. Free and ad-supported. Optional one-time purchase to remove ads.
