  • The Takahashi Epsilon 130D is a 130mm modified Newtonian design perfect for astro-imaging.
  • Features a digital correct allowing for improved field flatness.
  • Fast design is f/3.3 for short exposures without reducing.
  • Lightweight and highly portable at only 10.8 pounds.
  • Improved focuser design (over the original Epsilon) for precision focusing.
  • Classic Takahashi golden yellow finish.


Originally introduced in the mid 1980's, the smallest and most portable of the series has been reintroduced with a revised digital design.  Featuring a hypebolic primary mirror and a digital corrector to produce a beautiful flat field perfect for astro imaging.  Sharpness and clarity has been improved over the original Epsilon design.  The digital corrector produces a 1/3rd reduction in the size of the smallest stellar image and reduces distortion by 1/2! 

The Epsilon 180D has a 5.9º field of view making it a superior choice for imaging comets as well as planets.  Ultra fast design allows you to image without reducing with a focal ratio of just f/3.3.   To ensure that the image is evenly illuminated the secondary mirror has been placed in a specially strengthened spider so taht it can be held offset without flexure.  An improved focuser adds to the list of outstanding features on this 130mm astrograph.  Each metal insert has been coated with a special non-cold flow material to allow for extremely precise focusing.  To improve collimation, the collimation system for the TOA has been adopted for the Epsilon 180D.  Rather than using push pull screws set inside of each other they have been modified to use separate push and pull screws.  This allows the screws to sit flush avoiding the tube bumping the protruding alignment bolts.

The 130mm is also highly portable with a focal length of 430mm and weighing in at 10.8 pounds! A luxury grab and go set up it fits easily in travel cases without weighing you down.  Pair it with a lightweight EQ mount for Takahashi quality imaging, where ever you go. When planning out an imaging train and other accessories for use with the Epsilon, please refer to this useful System Chart.
