As we all know, ASA documentation is a major problem, with no comprehensive up to date manuals readily available.
However buried deep in the ASA web site (only accessible via Google, not via the download links on the site) is a folder that appears to be the documentation repository.
Type: "site:www.astrosysteme.at/images/" (without the quotes) into Google to list the folder contents.
Much of the documentation is only in German, a lot is very out of date, but it does include short notes on detailed aspects, that many of us have been given by ASA in response to questions, but which are not more widely published.
This may or may not help newcomers who are struggling!
