The Epsilon 180 by Takahashi©
Takahashi has recently introduced to the market the Epsilon-180 f/2.8.
This first addition to the new Epsilon Series introduces the newly designed ED corrector and fast speed of f/2.8.
This fast field photo visual astrograph is perfect for the new mega pixel digital 35mm cameras and CCD cameras. The great speed will enable the imager to record faint nebulosity invisible in slower instruments.
The appreciably shorter exposure times reduce tracking error and will produce very small stars. The E-180 will produce 10 micron star across the entire flat field.
