Description

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. The group is intended as a friendly place where people interested in these topics may carry out constructive discussions of their equipment, without most of the product bashing and personal feuds that sometimes dominate other venues. We are very fortunate that Roland and Marj Christen and some of their employees provide valuable contributions to the group.

I meant a regular eyepiece-end filter, like DayStar. Of course there is a front ERF, but the filter is eyepiece end. Pedro ... From: ap-ug@yahoogroups.com
