Optec Inc. Lepus HD Telecompressor for Celestron C9.25 EdgeHD: Enhanced Astrophotography Performance

Tailored for Celestron C9.25 EdgeHD: Specifically designed for the Celestron C9.25 EdgeHD OTA, which features a unique optical design compared to other SCT telescopes.
Aplanatic SCT Design: Incorporates a full aperture corrector plate and a 3-element corrector lens group in the baffle tube, making the C9.25HD a fully aplanatic SCT.
Optimized Back-Focus and Focal Ratio: Features an optimized back-focus of 146mm and a native focal ratio of about f/9.9, producing flat fields and sharp images.
Effective Focal Reduction: Attaching the Lepus-HD C9.25 Edition telecompressor reduces the focal ratio to approximately f/6.4, enhancing astrophotography capabilities.
Reduced Field of View with Light Correction: Yields an effective field of view of 28mm, with some light fall-off beyond 24mm, correctable through flat-fielding techniques.
Designed to Prevent Lens Contact: Includes a 5mm thick aluminum spacer to prevent physical contact between the C9.25HD's corrector lenses and the telecompressor lens.
Improved Astrophotography Results: Ideal for astrophotographers looking to achieve wider fields and faster imaging with the Celestron C9.25 EdgeHD telescope.
Compatible with Standard Imaging Techniques: Works seamlessly with standard flat-fielding techniques to correct any light fall-off, ensuring uniform image quality.
Professional Grade Accessory: Suitable for both amateur and professional astronomers seeking to enhance their Celestron C9.25 EdgeHD telescope's imaging capabilities.
Precise Engineering for Safe Usage: Carefully engineered to ensure safe and effective use without damaging the telescope's optics.
