130mm f/6.3 Starfire EDF - 5.12" aperture
with 2.7" Focuser

This webpage is a historical document. The information on this webpage is provided for present owners and those who are curious about its history.

The 130mm f/6.3 StarFire EDF "Gran Turismo", with optional accessories, sits regally atop a Mach1GTO Mount.

Astro-Physics introduced the prototype of this new triplet apochromatic refractor at the Northeast Astronomy Forum (NEAF) on April 28, 2007. Long-time followers will recall that we offered a 130mm f/6 StarFire EDFS refractor from January 1995 through December 2003. We have designated this new 130mm f/6.3 StarFire EDF as the "Gran Turismo" model to highlight its potential to travel to the four corners of the earth. The triplet lens is the same extraordinary quality that you have come to expect from Astro-Physics with a few new exciting features:

Several accessories have been designed with the Gran Turismo in mind, however they are also appropriate for other instruments of similar size. Please click on the links below for additional information.

The Mach1GTO German Equatorial mount is recommended for visual observation or astroimaging. The intuitive GoTo Keypad serves as a full-featured mini-computer or use a Planetarium program on your PC or Mac computer. You can even control the basic functions of mount with your mobile smart device.
