Takahashi Epsilon 160 ED f/3.3 Newtonian Astrograph Reflector
The Epsilon 160 ED is a compact, super-fast, highly portable flat field astrograph that weighs only 15.2 lbs! Designed for portable and ultra fast deep sky imaging the Epsilon 160ED is a perfect combination of light grasp, portability and superior quality.
It's compact size and ultra fast optics means it can be easily be transported to remote imaging locations and used with smaller, lighter high quality mounts.
The new Epsilon 160 ED features a number of improvements over it's Epsilon predecessors including a newly designed optical corrector that, together with a hyperbolic primary mirror, produces <10μm spots at the edge of the Ø44mm circle. Distortion has also been halved!
The fast f/3.3 optical system necessitates a large secondary mirror that fully illuminates the imaging field. The secondary mirror is set slightly off-centre to ensure it intercepts the full light cone and the spider (supports the secondary mirror) has been specially strengthened to achieve this without flexure.
The focuser too is new with a metal insert that has 'non-cold flow material' for more precise control.
Takahashi have also designed a new collimation system for the primary mirror, which is similar to the one used on their TOA. The previous design used push and pull screws set inside of each other. This new model uses separate push and pull adjusting screws and the alignment bolts are now flush with the end of the tube (they protruded on earlier Epsilon models) so are less likely to be bumped out of alignment.
With high precision and solid construction the Epsilon 160ED can be easily transported without losing collimation.
