The 99% dielectric diagonal of 50.8 mm 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.
