To minimize focuser in-travel, due to additional length, a mild 15% Barlow effect was designed into Paracorr to effectively push the focus out.

To accommodate for the differences, TeleVue developed the \"Tunable Top.\" The \"Tunable Top\" permits optimized aberration control for all \u003ca href=\"http:\/\/khanscope.com\/accessDetails.cfm?productID=5224\" target=\"blank\"\u003eTeleVue Telescope Eyepieces\u003c\/a\u003e and many others, by simply loosening a screw and rotating the Tunable Top.
