- Questions & Answers
Product QuestionsDoes the stated weight of the telescope (11 lbs) include the FLAT6A-102, and if not, what would be the weight including the flattener?The WO GT102 appears to come with a Vixen dovetail. Can a Losmandy 4" dovetail be substituted when ordering?Question by: Eldon Byland on Aug 29, 2016 10:57:00 PMUnfortunately, the manufacturer does not offer this scope with a D-series dovetail as an optional upgrade, but we do have lots of options. This plate will likely be the most cost effective: https://www.optcorp.com/ce-94214-universal-mounting-plate-cge.html.Answer by: Chris Hendren on Aug 31, 2016 11:33:00 AM
