The diagonal uses a 46mm minor axis mirror with 1/10th wave finish and each unit comes with an individual Zygo report so you can be sure of its quality.

Using the 4 screws on the back the position of the mirror can be altered to help collimate your telescope. The unit comes in a sturdy mini cerberus case which is just a tough as its larger brother.

 

Astronomy Now Review:

The diagonals mirror is of excellent quality, and observational comparison with one or two of my own diagonals gave me no cause to doubt that the 46mm (minor axis) mirror is as stated, one-tenth wave with 99 per cent reflectance.

The beauty of this system is that filters can be placed in this primary optical position, doing their task unmoved for any eyepiece or camera changes ‘downwind’.

True to its makers’ name, this diagonal is a precisely made piece of astronomical engineering, and I have no hesitation in recommending it.
