Ask a Question About This Product

Since the release of the Sharpstar 20032PNT, an extremely-fast parabolic Newtonian reflective astrograph customers now have a better option for their astrophotography activities. The 20032PNT is designed with a 200mm f/3.2 parabolic primary mirror, a 90mm-minor-axis flatten secondary mirror, a 3" four-element 0.85×coma corrector, which can reduce the original focal ratio to an amazing f/3.2. It comes second to none when compared with other domestic competitors. The main tube is solid and durably made of carbon fiber material, which is also stunning and lightweight. The mirrors are made from Pyrex-like material, more stable than traditional reflective glass.
Both mirrors have an advanced aluminum coating which ensures practical reflectivity up to 96%. The integrated strut supporting the secondary mirror is rigorously constructed. The spikes are not easily distorted or bent during use. The 3" rack-and-pinion focuser with its heavy-duty design makes sure the accessories are firmly attached and will not slip away.

All the connecting components are made from CNC manufactured aluminum. The artistically pierced tube rings and the neat-looking handle, together with upgraded mechanical performance can further satisfy the most demanding astronomy enthusiasts.
There is a four-element corrector laid in the optical path, an essential part in the whole optical system which guarantees sophisticated full-frame imaging and excellent vignette control. The focuser is tapped with M54×0.75 threads and designed with a standard 55mm back focus, user-friendly for customers wanting to attach most stock imaging devices. When threading on a M54-to-M48 adapter ring (standard), the back-focus is 52mm.
