Optec's #19405 Lepus-STL is a special version of the Lepus telecompressor featuring a male STL 2.156"x24tpi thread in place of the standard OPTEC-2100 dovetail. Designed especially for the SBIG STT-8300/FW8G/AO8 camera combination, many users prefer the threaded attachment over the dovetail and setscrew arrangement of the NextGEN and standard Lepus telecompressors.

The Lepus-STL version is compatible with the #19395 and #19397 VLC Variable Length Camera adapters and the optional #19391 STL to T-thread adapter. Be sure to set the back-focus distance correctly for your camera system. Back focus diagrams can be found at the bottom of this page.
