Product QuestionsQuestion by: Steve Peterson on Dec 15, 2016 7:58:00 AMAccording to Officina Stellare, this flattener actually has two optical configurations based on customer requirements for back focus and corrected image circle. The exact flange focal distance varies slightly by telescope aperture and flattener placement relative to the primary and secondary mirrors, but the two versions have approximately 200mm and 250mm back focus respectively.Answer by: Chris Hendren (Admin) on Dec 16, 2016 8:49:00 AM
