Optics are the heart and soul of any telescope no matter what electronic extras or accessories you buy with your telescope.

You will see that we offer different grades of optics for customers of our VX range and customers wishing to buy optical sets as a separate product. Our Professional Grade which has a guaranteed wavefront accuracy of 1/6PV wavefront and our Research Grade which is 1/8th PV wavefront. Finally, our Ultra range has Strehl values typically around 99% with RMS values of the order of 0.02PV. Coupled with a guaranteed PV wavefront error so small, it often is less than 1/10PV wavefront. All these are based on a test wavelength of 632nm generated by our Zygo.
