PRECISION ADJUSTABLE KNIFE EDGE FOCUSING TOOL

AeroQuest is offering a beautifully machined all aluminum, brass, and stainless steel Knife Edge Focusing Tool!  This tool can be adjusted to work with any 35mm camera, regardless of whether or not it's a single lens reflex.  All you need is the proper camera T-ring and this handy focusing tool can be easily calibrated to match the knife edge to the exact focal plane of your camera. 

• No more guesswork as to whether or not you're in proper focus! 
  

• No more 45 minute long exposures on that one perfect shot only to find out when you develop your film it was out of focus!
  

The only sure way to achieve perfect focus is to apply the same techniques used in precision lens and mirror making, and this tool uses the same knife edge testing of the focal plane.  Also, the adjustability is great if you switch to a different camera model …  you don't have to buy a whole new tool.  By screwing the knife edge in or out, the focal plane of your camera can be exactly matched!  Locking screws keep it there for repeated use.

This will be a nice addition to your collection of eyepieces and astrophotography hardware.  If you do a lot of astrophotography or plan to, you need this tool!
