The 99% dielectric diagonal of 31.8mm 90° allows you to comfortably use your telescope, adjusting the eyepiece to a much more comfortable observation position!

The diagonal is a very important part of the setup, so our diagonals are completely in metal and have a 99% dielectric treatment with a 1/10 lambda correction; all this to guarantee you excellent quality at a very low price!
A bad diagonal decreases both the brightness and the contrast of your instrument, replacing the classic diagonal supplied with our dielectric diagonal you will gain in image quality and mechanical quality.

Dielectric treatment and 1/10 lambda correction
Our Twist Lock diagonals guarantee you a brighter and more contrasted image than the common diagonals, furthermore the 1/10 lamba correction means that the returned image is impeccable!
Thread for 31.8mm filters
The diagonal is provided with a thread to screw 31.8mm filters onto the 1.25 "nose.
