estare was developed for aligning and stacking photos particularly astronomical photos, which may require careful adjustment before stacking. It is run in two modes: scan for feature detection, and stack for stacking up two frames. The former is a prerequisit for the alignment step. Run the scan mode to select features such as bright stars that are present in both frames that are going to be aligned. Later, when running the stack mode, the algorithm uses the coordinates obtained in the feature detection step to adjust the frames before stacking them up.

To install the current release, use one of the following methods.

pip install estare

Use this method if you intend to use estare as a command line tool. It is recommended to install the pip package in a virtual environment.

You can also download the package directly from GitHub.

If estare is installed using the pip distribution, you can run it from the command line by calling

estare scan ... or

estare stack ...

On the other hand, if it is downloaded as a package, it needs to be extracted first. Afterwards, you can run it like a package:

python -m estare scan ... or

python -m estare stack ...

In either case, use estare -h for a complete guide on how to run each mode.
