About this product
Takahashi Epsilon 130 ED f/3.3 Newtonian Astrograph Reflector
The Epsilon 130 ED is a compact, super-fast, highly portable flat field astrograph that weighs only 10.8 lbs!
It's compact size and wide 5.9° apparent field means it can be easily be transported to remote imaging locations and used with smaller, lighter high quality mounts.
The new Epsilon 130 ED features a number of improvements over it's predecessor including a newly designed optical corrector that, together with a hyperbolic primary mirror, produces <10μm spots at the edge of the Ø44mm circle (a 1/3rd better than the original model). 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 the earlier model) so are less likely to be bumped out of alignment.
The package version includes Tube Holder, 7x50 Finderscope and Bracket.
