For owners and users of the popular 80mm f/5 rich field and similar refractors (Orion Short Tube 80, Celestron 80WA, Konus Vista 508, etc.) Exchange ideas, modifications, accessories, etc.

Note: To prevent spam and such, membership is moderated. We approve *all* 80f5 interested folks - but I need a short message about your interest in this particular group to tell real people from the spambots. Due to a heavy workload, approval may take a week or two but it will happen. Thanks - and clear nights to you!
