101mm, f/5.4 APO (Nagler-Petzval) Refractor - Imaging/Visual.  Based on exemplary wide field and planetary visual scopes with added features to make imaging easier and more flexible. 4.9° / 250x (Max. Visual Field / Max. Rec. Power). CCD cameras have challenged telescope optics beyond anything ever placed at the focal plane. I knew our APO objectives were up to the challenge, and with the proper tweaks would be extraordinary tools for the imager. With Tele Vue Imaging System ("is") telescopes, we have refined our instruments and optional equipment beyond anything a CCD chip has seen. (Reviewer Note.) We started small (literally) in 2005 with the Tele Vue-60is and available Digital Micrometer Kit. Achieving critical acclaim with the 60is, we were encouraged to further develop "is" telescopes and accessories to maximize aperture, real field coverage and performance, and to make the processes easier for the imager. - Al Nagler
