My Telescope Equipment list includes a Tele Vue-85 (FL = 600mm) telescope and a Tele Vue Delos 4.5 eyepiece. When I try to add a Telescope Scope Display (Field of View), I can select the 85 and the 4.5, but when I click "OK" the added FOV shows "Tele Vue-85, 24mm Plossl". (Such an eyepiece does occur in my equipment list with no manufacturer specified.) The same thing happens when I try to make a FOV for a different telescope and the 4.5 -- I get a new entry "C8-SCT, 24mm Plossl".
Any suggestions?
