Here is a recent test report from an AG Optical Systems 17" iDK F6.7 quartz telescope. The set was tested using double pass interferometry taking hundreds of data points across the wavefront of the optical system to generate a quantitative assessment of the optical quality of the system. Ask the other guys what guarantee they provide that the optics in that expensive scope are of high quality?

We encourage your to conduct a direct comparison to competing products. Ask them who makes their optics and how they test them. Also, be sure to compare what is included at the base OTA price.
