130mm f 6,3 StarFire GTX Triplet Apochromat Refractor
"Grand Turismo"
This refractor is the fourth in the 130 series at Astro-Physics. Long-time followers will recall that Astro-Physics offered a 130mm f/6 StarFire EDFS refractor from 1995. The current model offers some improvements over the last older version.
- Compact, lightweight tube assembly that can be disassembled into two parts to fit into your carry-on luggage. Optional machined aluminum covers are used to close and protect each end of the tube. Note that the optional covers are attached to the components
- High qualitiy 3.5" Astro-Physics focuser - silky smooth with a greaseless drawtube and the dual-speed mechanism of the FeatherTouch 9:1 Micro. The dual-speed feature is particularly advantageous for critically focusing this fast focal ratio. A digital focusing system is available for imaging
- Rotating focuser "captain's wheel" collar will enable you to frame your images for optimal, artistic composition or to keep north up
- fully retractable felt-lined dewcap slides to its fully extended position and then uses a twist-lock feature to secure it in place
- Latest multi-coating technology will provide optimum light transmission
The Mach1GTO German Equatorial mount is recommended for visual observation or astro-imaging. The intuitive GoTo Keypad serves as a full-featured mini-computer or you can use a Planetarium program on your PC or Mac computer. You can even control the basic functions of the mount with your mobile smart device.

Optional 0.72x Quad Telecompressor Corrector (#1405380 , € 2350,-)
This Reducer/Corrector reduces the focal length of the 130GTX from 820 to 585 mm and gives you a focal ratio of f/4.5. For a full frame camera (24 x 36 mm) this results in a field of view of 3.5 x 2.4 degree at an image circle of 50.2 mm, diffraction limited and free of vignetting.
As with all optical systems which change the focal length, the distances between lenses and camera sensor have to be kept as exact as possible. This is why there are several camera aptations available for this flattener. Further informaton are available on our website or on the Website of Astro-Physics.
Upgrade the 130 EDF-GT to the new 130 GTX:
130 Starfire EDF-GT owners can celebrate with the knowledge that their 2.7" focusers can be upgraded with the 3.5" focuser and then also use the Quad TCC.
Note: if you already own the 2.7" Prime Focus Field Flattener for the 130mm f/6.3 Starfire EDF, the optics can be installed into the new housing (# 140 5352) for the 3.5" focuser. If you are interested, please contact us.
Included:
- Tube Assembly with 3.5" Focuser, Dew Shield and Dustcover
- 2.7" 2" and 1.25" Adapters
- Carrying Case
Mounting rings and/or mounting plates are not included.

Astro-Physics – High-end German Equatorial Mounts
HIGH-QUALITY PROFESSIONAL ASTRONOMICAL MOUNTS Keeping to the same quality standards that have made the fully-apochromatic refractors legendary, Roland Christen's company has been building German Equatorial GoTo mounts for more than three decades. Their proven stability, accuracy and durability is the reward for anyone who can endure the traditionally long delivery times. Two "el Capitan" mounts are working in the Antarctic for several years now, even at temperatures of -75°C. They are perhaps the most spectacular example of the durability of the sturdy Astro-Physics mounts and are representative for many more exemplars that often run for decades at our customers without failures. With a very accurate manufactured worm gear the Astro-Physics mounts are equally well-suited for smooth, effortless tracking of celestial objects as well as for all visual and photographic purposes. Astro-Physics supplies 4 mounts with 30kg to 135kg instrument load. The GTO 1100 and GTO 1600 series are especially remarkable, because they are fully transportable - despite their high instrument load. This is possible because the declination axis can be separated from the rest of the mount. Even the GTO 1600, with 90 kg instrument load, can be transported and set up by one person! The connection of the two...
