Greetings! This is a discussion group for both owners and those interested in Astro-Physics astronomical products, including scopes, accessories, and images made by AP scopes. Mount discussions are also welcome, although there is a separate group (ap-gto) for specific issues relating to AP GOTO mounts.

We are very fortunate that Roland and Marj Christen and some of their employees provide valuable contributions to the group.
