Our Take
The Esprit 150mm has all the elements of a "forever" scope. The large aperture provides stunning views of celestial objects. At f/7 it is well-suited for astrophotography and the included field flattener provides pinpoint stars across a full-frame DSLR. The performance of the Esprit 150 will leave you to want for nothing!
