We're running our Spring Break Special this week and are 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!

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!

To celebrate Spring Break (and to keep myself busy), we are including a FREE True Knife Accessory with every Series III order. You save $15 and gain perfection at the same time. Don't delay because this offer
expires MARCH 18th (when I go back to school)!

To learn more about the Series III and knife-edge focusing, just visit
our website and take a look at our special tutorial on how it all
works.

Clear Skies and a Happy Spring Break !
Richard
