Check out our brand New 2" Diagonal. Why is it different from all previous star diagonals?

1. It features our new  Denk Inter-Locking Visual Back (DIVB) !  This diagonal is easy to reposition when your wedge mounted or EQ mounted SCT changes position. You can quickly de-couple the diagonals patent pending DIVB and rotate the diagonal to the ideal position. Then re-engage the parts and turn in a thumbscrew. No force is required and it cannot rotate downward accidentaly!
2. Features 99% reflective Dielectric coatings for the brightes views possible.
3. 1/10th flat substrate 
4. If using a Denk Binoviewer and you wish to shorten the lightpath, the diagonal's eyepiece holder is removable. Then, the binoviewer may be docked directly to the diagonal's body, removing 38mm of lightpath. This is ideal for special shortened refractors as well. No need to go to a 1.25" diagonal to shorten a lightpath when a refractor does not quite have enough in-travel.
