Tele Vue Optics Tunable Top with 1¼” adapter

Tele Vue Optics Tunable Top with 1¼” Adapter: Precision Coma Correction for Paracorr Type-2 Enhanced Coma Correction: Designed to position all eyepieces for optimal coma correction, enhancing your viewing experience. Versatile Compatibility: This 2" Tunable Top with 1¼” Adapter (model #ATT-2125) is compatible with the standard Tele Vue 2” Paracorr Type-2. BIG Paracorr Type-2 Adaptability: For use with the BIG Paracorr Type-2, the “VISA” (Visual / Imaging System Adapter) is required. No Need for 3” Tunable Top: Due to secondary mirror size limitations, a 3” Tunable Top is not necessary, maintaining a manageable setup. Ideal for f/3 Telescopes: Best suited for f/3 telescopes (effectively f/3.45 with Paracorr), particularly with Tele Vue’s 21mm Ethos eyepiece for a 6.1mm exit pupil at f/3.45. Perfect for Wide Field Eyepieces: Maximizes the performance of wide field eyepieces, making it a great addition for serious astronomers and astrophotographers.
