About this product

Model:  optec_lepus_19407
Part Number:  19407

The Optec Lepus 0.62x is a 4-element telecompressor designed by Optec engineers to work with newer, well-corrected Schmidt-Cassegrain telescopes such as the Meade ACF and the Celestron EdgeHD series telescopes. 

Also known as a focal-reducer, the Lepus provides a 0.62x reduction of the telescope's effective focal length. 

The Optic Lepus works well with most mid-size CCD cameras and Digital SLR cameras having sensor diagonals up to 28mm. 

Optimized for 100mm of distance between the last lens surface and the image plane. Measured from the telecompressor flange, this distance works out to 105mm.

Assuming a native focal ratio of f/10, the Lepus 0.62x will reduce the effective focal ratio to approximately f/6.2. Shifting the image plane outward will provide additional reduction but a loss of star quality at the edge of the images. The optimal distance for most SCT's is 100mm with the exception of the C9.25 EdgeHD SCT. 

Designed for use with midsize CCD's and DSLR's

The Optec Lepus 0.62x can will deliver a fully unvignetted image 22mm in diameter, but will provide well-corrected images out to 28mm with a small amount of light fall-off.  Flat fielding is recommended for best results. See Optec's line of Alnitak flat-fielding devices for additional details.

NOTE 1: The #19407 Lepus 0.62x 'Standard Edition' does not include a camera specific mount. Be sure to select one of the Variable Length Camera mounts or contact us for advice on a fixed length camera mount suited to match your imaging system. 

NOTE 2: The Lepus 0.62x can be used with other telescope designs but is not parfocal. Therefore, some re-focusing will be required.  Performance is not guaranteed with all telescope optical designs and the Lepus is not recommended for use with Ritchey-Chretien telescopes.
