STI Lightpen Weight: lbs ! We have had numerous requests to offer our exclusive lightpen separately for quite a while.  This item is already included free with any purchase over $99, but it is so nice and useful for working in the dark that customers are asking to purchase them for their friends.  The blue LED light provides just enough light to be able to read and write in the dark without impairing night vision.  The battery provides many hours of use and is easily replaceable.

Series IV Carrying Case Weight: lbs ! Onsale today! This sturdy carrying case measures 10x10x4 and contains die-cut foam to well protect the Series IV and components during travel or storage.  Black with STI logo.

Series IV Black Chromium 300 line/inch Ronchi Grating Weight: lbs ! Our black chromium screen is interchangeable with all of our other ronchi screens.

Series IV True Knife-Edge Screen Weight: lbs ! Our True Knife-Edge accessory is interchangeable with all of our other focusing screens on the fly.  No recalibration is necessary when swapping between screens. The knife-edge screen is manufactured by evaporating black chromium on the BK7 optical glass substrate.  The edge is fifty times sharper than an actual razor blade.

Series IV Body Module Weight: lbs ! The Series IV body module comes complete with our 25mm focusing eyepiece.  The body may be used with any Stiletto camera mount housing a ronchi screen or True Knife-edge accessory.  Owners of a CVF focuser and mount with a ronchi screen may easily swap mounts between the CVF and the Series IV body. Note: Ground glass screens such as our Spotlight and Crosshair screens will not operate properly with a Series IV body due to differences in the actual focusing procedure.

Series IV Upgrade Weight: lbs ! Series IV Upgrade Owners of previous Stiletto versions may easily upgrade to the current Stiletto Pro Edition. Your current unit must be returned to us.  Please give us a call for further information.
