The Antares 90° Dielectric collimatable diagonal is a high-quality diagonal which can be collimated to deliver the optimal image.
Features Antares compression ring system which tightens evenly around the eyepiece without the use of thumbscrews on both the 1.25" and 2" receptacles.
The image produced is N-S correct, and E-W reversed when the eyepiece is pointing straight up.
For use with Refractors or Cassegrain-style scopes only. Schmidt-Cassegrains require a low-cost 2" visual back, or a 2" focuser upgrade.
