Description
100 field at 96 a planetary and lunar powerhouse. At 80mm aperture, this magnification extracts meaningful planetary detail on most nights.
Final Thoughts
The 80 GPS is built for the observer who wants a premium triplet APO that works as hard for imaging as it does at the eyepiece without carrying the weight and mount demands of a larger instrument. The triplet optics at f/6 deliver color-free views and round stars across the field. The integrated CAA and M63 flattener threading make it a complete imaging platform. The hidden flange plate lets you chase perfection when the data demands it. And at under eight pounds, it still fits in a soft bag and rides comfortably on a small equatorial mount. This is the 80mm triplet that doesn’t ask you to choose between visual and imaging it does both, and it does both well.
