be placed between the camera lens and the Achromatic Lens. The correct accessories for your 

camera are listed in the table on page 10 of this manual. 

 

Stabilize your camera by mounting it in your tripod to prevent accidentally touching any optical 

elements while attaching the Achromatic Lens to the camera.  The industry standard M2 Quick 

Release Plate should work with your fluid head tripod. 

 

Remove your camera’s lens hood. 

(Store the lens hood for later use.)

 

 

Remove any lens filter that is already in the camera’s screw mount.  

(Many people keep a clear glass 

filter or a clear UV filter attached to their camera at all times to protect the camera’s lens.  Some filters 

have a threaded front to permit other filters to be attached. Any lens filter  should be removed as it will 

change the distance between the Achromatic Lens and the camera lens. Store the lens filter for later 

use.) 

 

 

 

If your camera requires an optional adapter ring, attach these to your camera first by screwing them 

into the camera lens mount in a clockwise direction. 

 

If your camera requires an optional spacer tube, attach the spacer tube between the achromat and 

the adapter by screwing in to the back of the adapter. The achromat should always be placed as 

close as possible to the camera’s lens. 

 

To ensure that there is no dust between the Achromatic Lens and the camera lens, remove dust from 

the optical elements by blowing compressed air on them. 

 

Attach the M2 Achromatic Lens to your camera by screwing it into the camera lens mount (or the 

adapter ring or the spacer tube) in a clockwise direction.  The Achromatic Lens should have a firm fit 

but should not be over tightened.   

 

3. 

Attach the camera assembly to the Rod Support. 

Remove the camera from the tripod.  Slide the camera with the quick release plate into the M2 Rod 

Support base and secure it using the M2 Rod Support Quick Release Clamp on the side. 

 

4. 

Slide the M2 adapter onto the rods. 

Slide the M2 Housing onto the rods.  Push it forwards until the flexible hood on the back of the M2 

Housing just touches the front lip of the Achromatic Lens.  Secure the M2 to the rods using the clamp 

on the side of the M2 Rod Housing. 

 

Examine the relationship between the hood and the Achromatic Lens.
