Command-line toolkit for astrophotography stacking and compositing

Aquila is a fast, terminal-native toolkit for reducing and compositing astronomical image data on Linux. The image processing heart is written in Modern Fortran with OpenMP parallelism. It fits naturally into shell scripts and automated pipelines.

The package includes three programs:

  • aqstack: calibrates and stacks monochromatic CCD frames. Handles bias, dark, and flat subtraction, hot pixel correction, frame alignment, and combining by average, median, or sigma-clipped mean. (stable)

  • aqlrgb: composites multi-filter data into colour images. Supports the classic LRGB workflow as well as narrowband palette mixing, white-balance equalization, background suppression, and nonlinear stretching (asinh, sqrt, log) before writing FITS or PNG output. (stable)

  • aqcli: a scripting interpreter for writing end-to-end image processing pipelines. Scripts load frames, run calibration and stacking routines, apply convolution kernels and math operations, and save results — all in a compact, readable domain-specific language. (Still in early development)
