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!
