The SkyWatcher 130 f/5 photographic Newton is a small and compact telescope 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 Newton f/4. This allows for the use of the photographic reflector on visual observations and high resolution imaging of planets and the moon.

The optional SkyWatcher coma corrector for f/5 Newton corrects the coma superbly, offering a large corrected field for astrophotography.

The 2" Crayford focuser is solid, precise and backlash free. It operates at two speeds due to the 10:1 reduction mechanism for an extra fine focusing adjustment, which is paramount for astrophotography and high resolution observations.

The oversized secondary mirror is collimable by using 3 grub screws and the offset can be adjusted by using the central spring loaded screw.

The primary mirror is collimable with 3 pairs of push & pull screws. 

The aluminium tube is internally blackened to avoid internal reflection, enhance contrast and to absorb stray light.
