SharpStar D 150mm f/2.8 HNT: An imaging telescope with sharp vision
Until comparatively recently, your best tool for capturing wide-angle vistas of extended deep-sky objects with a full-frame DSLR or CCD/CMOS camera was a fast prime lens from one of the big-name players in photography. Now you can attain these swift imaging speeds with hyperbolic Newtonians, such as the SharpStar 15028HNT.
