Description
The 125 GPA is built for the observer who has learned that the best telescope is the one that gets used. At under 13 pounds, it’s a five-inch refractor that travels. The removable extension tube means binoviewer owners don’t have to compromise. The Super ED doublet at f/7.8 delivers color correction and contrast that will satisfy planetary observers and deep-sky hunters alike. Five inches of unobstructed aperture resolves detail and gathers light that no four-inch scope can match and the 2024 redesign made the whole package light enough that you’ll actually carry it to the car on a clear Tuesday night instead of talking yourself out of it. That’s the scope that logs the hours. That’s the one that shows you things.
