A lot of astrophotographers are unaware that the Series III
'Stiletto' is a true knife-edge focuser. While our regular
ronchi gratings are easier to use, the True Knife-Edge Accessory
will convert the Series III 'Stiletto' to a premier knife-edge
focuser in seconds. 

To kick off the holiday season, those purchasing a Series III focuser
from now until Christmas will receive our True Knife-edge Accessory
absolutely FREE! That's a $15 savings!

Compared to other knife-edge approaches, the Series III offers
tremendous advantages in convenience and seeing. The Series III
magnifies the light pattern for easier detection of the exact focal
point, and the swivel diagonal allows you to put yourself in a
comfortable viewing position. And, needless to say, your focus will
be perfect every time!

Series III focusers are available for Nikon, Olympus, Minolta, Canon
and other fine 35mm systems, as well as for CCD cameras manufactured
by S.B.I.G., Meade, Starlight XPress, and others. We do have one for
you!

To learn more about true knife-edge focusing, visit our website and
take a look at our new tutorial on how it all works with the Series
III. You and your astrophotos won't regret it!

Happy Holidays and Clear Skies!
Richard
