SKYWATCHER PHOTOGRAPHIC NEWTONIAN 250 F/4.7 small case please contact usThe SkyWatcher 250 f 5 photographic Newtonian telescope is optimized for astrophotography. In fact, its oversized secondary mirror provides a large illuminated field that is ideal for large camera sensors. This telescope has a fast f 5 focal ratio and while the coma is still visible, it is 36% lower than the coma in a Newtonian f 4. This allows for the use of the photographic reflector on visual observations and high resolution imaging of planets and
