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.
Recommended aliases:
sudo snap alias aquila.lrgb aqlrgb
sudo snap alias aquila.stack aqstack
sudo snap alias aquila.cli aqcli
The package includes three programs:
aqstack or aquila.stack: 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.
aqlrgb or aquila.lrgb: composites multi-filter data into colour images. Supports the
classic LRGB workflow as well as narrowband palette mixing, white-balance
equalisation, background suppression, and nonlinear stretching (asinh,
sqrt, log) before writing FITS or PNG output.
aqcli or aquila.cli: 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.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install aquila, simply use the following command:
sudo snap install aquila
Browse and find snaps from the convenience of your desktop using the snap store snap.
