Astrophotography Gallery & Sky Map Guide
Welcome to your interactive astrophotography portal! This website projects real astrophotography images directly onto an interactive 3D map of the celestial sphere using WCS astronomical alignment. Here is how to use the site:
1. Exploring the 3D Sky Map
Pan & Zoom: Click and drag anywhere on the sky map to move around the night sky. Scroll your mouse wheel or pinch on mobile touchscreens to zoom in and out.
Celestial Surveys: Click the survey dropdown in the top header to switch background surveys between Optical (DSS2/PanSTARRS), Infrared (2MASS/WISE), and H-Alpha.
2. Filtering & Locating Target Photos
Filter Catalog: Use the left sidebar to search by target name or filter by Object Type (Nebula, Galaxy, Star Cluster), Telescope, or Constellation.
Locate on Map: Click Locate on any photo card to fly the sky map directly to that object's position in space.
3. Floating Sky Map Controls
Show All Photos: Master toggle to turn all photo overlays on or off on the sky map simultaneously.
Map Layer Switches: Use the switch on any photo card to toggle individual photo projections on or off one by one.
Footprints & Labels: Toggle FOV framing borders and target name badges on or off.
Opacity Slider: Adjust the transparency of photo overlays against the background sky survey.
4. FITS Metadata & Header Inspection
Click any photo card to open the Detail Inspection Modal. Explore high-resolution previews, exact RA/Dec astronomical coordinates, FOV sky dimensions, and raw FITS metadata headers parsed directly from capture logs.

Enables guaranteed blind pattern solving for wide-field, cropped, or faint star images. Saved in your browser.
Guaranteed Background Solver (Astrometry.net)
Fast local ASTAP could not match stars. Astrometry.net performs comprehensive blind pattern matching across any scale or optic. It runs asynchronously in the background so you can close this window and keep exploring.
