If you have a Nikon or Olympus 35mm camera, you are in luck this week!
We're running our Spring Break Special and including our True Knife-edge Accessory FREE with each order of a Series III.
You can save $15 and get a perfect picture at the same time!
STI has astrofocusers for every major brand of 35mm (Nikon, OM, etc.)and CCD cameras (SBIG, Starlight, Meade). Yours too! Don't delay because this special offer expires MARCH 18th!
A lot of astrophotographers are unaware that the Series III
'Stiletto' is actually a true knife-edge focuser. While our standard
ronchi gratings are far easier to use, the True Knife-Edge Accessory
will convert the Series III 'Stiletto' to a premier knife-edge
focuser in seconds. Our True Knife-Edge is interchangeable with the
ronchi screens we use, and requires no recalibration at all. The
changeover from one to the other takes about a minute. If you've got
the patience to learn how to use a knife edge, we have the technology!

Clear Skies and a Happy Spring Break !
