TAKAHASHI TOA-130NFB Ortho-Apochromat Triplet Refractor w/ Temma 2 Mount, SE-L Tripod, and 4" Focuser - PACKAGE
The TOA-130 (130mm; 5.1") is the first of Takahashi's newest optical design, the Ortho-Apochromat Triplet. This technology employs newly designed triplet objective lens sets using special elements to produce the highest order of color correction packaged in a short 32” tube (lens shade retracted). Takahashi has been the acknowledged leader in ultra-premium apochromatic optics for almost three decades. The new TOA and TSA Series of triplet refractor optical systems show Takahashi's dedication to quality and development of cutting edge technologies.
The Takahashi triplet ortho-apochromatic (TOA) refractors use a newly developed lens design that uses three air-spaced lenses in three groups. The Ortho-Apochromatic Triplet lens design incorporates an FPL-53 Extra-low Dispersion glass element sandwiched between two crown glasses to eliminate chromatic aberration and produce images of extremely high quality . All lens surfaces are fully multicoated with state-of-the-art antireflection materials for maximum light transmission. With numerous internal knife-edged baffles light "scatter" is kept to an absolute minimum producing an image with amazing contrast. O.K., but what is an Ortho-Apochromat ?
- Apochromatic means “free from spurious color” – a design that drastically reduces the faint violet halos of out-of-focus light that you see around the planets, the limb of the Moon, and all the bright stars in an ordinary achromatic (crown and flint glass) refractor.
- Orthoscopic means “visually correct,” and is most commonly is associated with an eyepiece design widely regarded as having the most accurate and aberration-free images available.
All Takahashi TOA and TSA Series triplet refractors are true apochromatic optical systems, with virtually perfect correction of spurious violet color. Their colors are highly saturated, full of contrast, and true to life. They combine virtually non-existent levels of spurious color with equally low levels of optical distortion. Consequently, they are called “Ortho-Apochromats” to distinguish them from ordinary apochromatic scopes. The maximum deviation from all colors coming to a focus in precisely the same plane is no more than +/- 0.01mm from the blue end of the spectrum (436nm) to the H-alpha line at 656nm. The violet halo of chromatic aberration vanishes, and the tiny residual blue halation around bright stars at high powers essentially disappears.
The TOA-130 is perfect for both Visual exploration and CCD or Classic astrophotography. The f/7.7 focal ratio with a 1000mm focal length is long enough (using the optional LE-ED 2.8mm Takahashi ocular) for high magnification observations of the Moon and planets and yet will produce a 2.5° field at 20x when used with the optional Takahashi flat field LE-50 2“ ocular. Ample back focus, (over 200mm from the rear cell), has been designed into the system to permit the user to use a variety of CCD cameras, color filter wheels and electronic focusers or film cameras.
This TOA-130 NFB variant, called the "F version", features a heavy-duty oversized 4" rack-and-pinion focuser with a 360°camera angle adjuster, and is perfectly adapted to serious Astroimaging as well as Visual exploration. It provides 1000mm focal length and an f/7.7 focal ratio, which provides a 92mm image circle and a photographic field of 5.3 degrees for unvignetted imaging. Outstanding resolution of 0.89 arc seconds and limiting visual magnitude of 13.1.

The EM-200 Temma-2 GEM and Extra Length Hardwood Tripod:
The EM-200 Temma 2 is an accurate, precision-built GoTo German equatorial mount that provides a stable platform for payloads of up to 40 pounds.
The modern aesthetic design of the EM-200 is highly attractive as well as beautifully functional. The RA and DEC stepper motors are fully integrated into the mounting,and the high precision design and construction provides cyclic errors lower than +/- 5 arc seconds.
The integrated polar alignment telescope has an illuminated reticule which can be dimmed to suit the user or observing conditions. In conjunction with the precision altitude and azimuth adjusters, this will typically give polar alignment accuracy within 2 minutes of arc of the celestial pole.
Included in this package are an RS232C cable, ST-4 or ST-7 cable, shaft encoders, hand controller, power cord for both 12V and 24V operation, and software.
The new style EM-200 mounts include the ability for operation on 12v or 24v and feature high speed slewing at 350x [sidereal rate] at 12v and 700x at 24v. 12V operation takes place with the use of the hand controller only. The mount will then function just like the EM-200 USD model (no GoTo functions). However, with the use of the hand controller and your PC, you can operate with 12V or 24V (two 12V batteries connected in series). 12V will give you a slewing speed of up to 350X sidereal, and 24V will produce slew speeds of up to 700X. A PC is required to actuate the GoTo functions on this mount. A dual-axis hand controller and power cable for 12V/220V battery connection is included.
