This project generates a mosaic of Messier or Caldwell objects, using images from a local folder.
The script arranges the objects into a configurable grid, supports larger slots for extended targets (e.g. Andromeda), and overlays labels and a title.
Perfect for creating a large-format print.
Features:
+ Loads Messier or Caldwell object images from a folder (M31.jpg, M-31.png, M_31.tif, etc.)
+ Places objects on a grid with configurable layout
+ Supports multi-cell slots for large objects (e.g. M31, M42, M45)
+ Supports grouping multiple objects in one slot for objects close to each other (e.g. M42 and M43, M31 and M32)
+ Adds a title and progress counter if it's not completed yet
+ Draws labels on images and placeholders for missing ones
+ Adjustable size of the final image
+ Saves as JPEG, PNG or TIFF
