Description

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.

Penelope U. ★★★★★

Getting the spacing right for my STL camera setup took some trial and error, but the male thread engagement is precise and rock-solid. I've already noticed sharper stars across my entire frame compared to the old focal reducer I was using.

Julian ★★★★★

The STL thread on this adapter matched my camera perfectly, no adapters needed. Star shapes are noticeably tighter across the whole frame now.

Elizabeth W. ★★★★★

I was worried about back focus, but this adapter threaded on smoothly and left just enough room for my filter wheel. The male STL thread is machined precisely—no wobble at all.
