#### 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)
