Takahashi CCA-250 Modified Cassegrain Telescope [TK-TCK25010]
$15,620.00 USDspecialorderScheduled DeliveryTakahashi America: The CCA-250 is Takahashi’s modified Ritchey–Chrétien, developed as a replacement to the BRC-250 and is designed with imaging in mind. The CCA-250 produces a flat field across an 88 mm image circle. At prime focus, it is a 250-mm aperture, f/5.0 astrograph. Coupled with a reducer, it becomes a fast f/3.6 telescope. The CCA-250 has a carbon fiber tube and a temperature compensated lens cell to maintain focus during long exposures. The CCA-250 also has an ASCOM compliant active focus system that enables computer control of the focusing system.

Takahashi EPSILON E-130D [TK-TEK13010]
$3,000.00 USDspecialorderScheduled DeliveryTakahashi America: The Epsilon series of astrographs are specifically designed for exceptional astrophotography. Takahashi’s proprietary optical design features a hyperbolic, concave primary mirror with a 2 element ED corrector lens to eliminate spherical aberration and coma. Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.
The new ε-130D is the same aperture as the original but now uses a digital corrector. This corrector produces improved sharpness and a 1/3rd reduction in the size of the spot equaling the spot size of the E-180 at the edge producing a 44 mm diameter circle. The offset secondary insures better illumination of the image formed by the primary.
The ε-130D has a 5.9° field of view which is perfect for imaging wide field objects like comets and objects with extended nebulosity. With a speed of f/3.3 and a focal length of 430mm the ε-130D will shorten exposure times, increase color saturation and will produce wide field high performance images.

Takahashi EPSILON-160ED Astrograph [TK-TEK16010]
$4,670.00 USDspecialorderScheduled DeliveryTakahashi America: The E-160ED reflecting telescope has an aperture of 160 mm and a focal length of 530 mm and provides a well corrected flat field for full frame imaging sensors.
The Epsilon series of astrographs are specifically designed for exceptional astrophotography. Takahashi’s proprietary optical design features a hyperbolic, concave primary mirror with a 2 element corrector lens to eliminate spherical aberration and coma. Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.The E-160ED reflecting telescope has an aperture of 160 mm and a focal length of 530 mm and provides a well corrected flat field for full frame imaging sensors.
Thorough aberration correction is realized by by optimizing the interaction of the hyperbolic mirror and the corrector. By using ED glass in the corrector, a spot image within 3 μm has been achieved at the periphery of a full frame imaging sensor. The E-160ED combines the ease of handling of the E-130D with the high performance of the E-180ED.
The eccentric oblique mirror and the spider vane design are used to suppress the scatter of light similar to the current epsilon models. The method of holding the primary mirror uses the same system as E-180ED. The optical axis adjustment screw of the primary mirror has a structure in which push screws are arranged on both sides of the pull screw. The central cover can be removed to allow for rapid temperature acclimation. NOTE: The corrector for the E-160ED cannot be used with the older E-160 OTA. Price includes OTA only. Mount, tripod, finder and camera sold separately.

Takahashi EPSILON-180ED Astrograph [TK-TEK18010]
$5,520.00 USDspecialorderScheduled DeliveryTakahashi America: The Epsilon series of astrographs are specifically designed for exceptional astrophotography. Takahashi’s proprietary optical design features a hyperbolic, concave primary mirror with a 2 element ED corrector lens to eliminate spherical aberration and coma. Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.
The ε-180 was introduced by Takahashi as the first of the new Epsilon flat–field hyperbolic astrographs since the 1980’s. The ε-180 was designed to be a very fast f/2.8 imaging system.
This fast field photo visual astrograph is perfect for digital SLR's and CCD cameras. The f/2.8 speed will enable the imager to record faint nebulosity not visible in slower instruments. In addition, the appreciably shorter exposure times reduce tracking error and will produce pin point stars. The ε-180 will produce 10 micron stars across the entire 44 mm diagmer flat 5 degree field.
The focuser has been improved to allow more precise focusing. Each has a metal insert with a special non-cold flow material to allow for correct focus.
