Starizona SCT Corrector LF - Large Format Reducer / Coma Corrector Lens - SCTCORR-LF

Introducing the Starizona SCT Corrector LF - a Large Format Reducer/Coma Corrector Lens.

Starizona's original SCT Corrector garnered widespread acclaim for enhancing optical performance and widening the field of view in standard Schmidt-Cassegrain telescopes.

Now, meet its large-format counterpart, designed to accommodate full-frame (35mm format) sensors.

Tailored for Celestron 11" and 14" standard SCTs, the SCT Corrector LF seamlessly threads onto the substantial 3.29" threads of C11 and C14 telescopes.

Its larger optical elements effectively minimize vignetting over expansive sensors. Any residual vignetting, a result of telescope baffles optimized for slower focal ratios, can be easily corrected using flat field images.

The SCT Corrector LF delivers exceptional sharpness over a 42mm diagonal, with spot sizes reduced by up to 9 times compared to the native telescope.

This translates to a notable increase in speed, with the C14 achieving f/7.2 and the C11 operating at f/7, representing speed gains of 2.1x and 1.9x respectively.

Moreover, the SCT Corrector LF provides extended backfocus compared to Starizona's standard SCT Corrector, offering a total of 146mm to accommodate an array of accessories.

The rear threads of the SCT Corrector LF match those on the rear cell of C11 and C14 telescopes, ensuring easy attachment of standard accessories.

Elevate your astrophotography experience with the Starizona SCT Corrector LF - the ideal tool for capturing stunning celestial images.

In the diagram above, we compare spot sizes between a native C14 at f/11 and a C14 at f/7.5 equipped with the SCT Corrector LF.

Each small square represents 40 microns. The RMS spot size at the edge of the field for the native C14 is 106 microns, while the SCT Corrector LF achieves an impressively minimal 13 microns.

 


Features and Highlights:

  • Fully AR Coated Optics: The SCT Corrector LF is equipped with fully anti-reflective (AR) coated optics. This advanced coating technology minimizes light reflections, ensuring maximum light transmission and enhancing image contrast and clarity.
  • Designed for Celestron 11" and 14" Standard SCTs: Specifically engineered for use with Celestron 11" and 14" standard Schmidt-Cassegrain telescopes, the SCT Corrector LF is tailored to complement these specific telescope models.
  • Direct Threading onto Rear Cell of C11 and C14 Telescopes: The SCT Corrector LF is designed to thread directly onto the large 3.29" threads located on the rear cell of Celestron C11 and C14 telescopes. This seamless integration minimizes vignetting over large sensors, ensuring optimal imaging performance.
  • Minimized Vignetting over Large Sensors: The larger optical elements of the SCT Corrector LF work in concert to minimize vignetting, particularly when using full-frame (35mm format) sensors. This feature contributes to clear and unobstructed imaging across a large field of view.
  • Excellent Sharpness Over a 42mm Diagonal: The corrector lens delivers outstanding sharpness over a 42mm diagonal, resulting in high-resolution images with fine details. Spot sizes are reduced to a remarkable degree, significantly enhancing image quality.
  • Focal Ratio Reduction: The SCT Corrector LF reduces the focal ratio to f/7.2 on the C14 and f/7 on the C11. This represents a notable speed increase of 2.1x and 1.9x, respectively. This enhancement allows for shorter exposure times and improved efficiency in astrophotography.
  • Increased Backfocus of 146mm: The SCT Corrector LF offers an increased backfocus compared to Starizona's standard SCT Corrector. With a total backfocus of 146mm, it provides ample space to accommodate a variety of accessories, allowing for a more versatile and customized astrophotography setup.
  • Compatible with Standard Accessories: The rear threads on the SCT Corrector LF are identical to the 3.29" threads found on the rear cell of Celestron C11 and C14 telescopes. This ensures easy attachment of standard accessories, providing flexibility in configuring your telescope setup.
  • Made in USA: The SCT Corrector LF is proudly manufactured in the United States. This ensures high-quality craftsmanship, precision engineering, and adherence to strict quality standards.
