130 mm f/6.3 Starfire GTX

with 3.5" Focuser

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


Astro-Physics introduced the re-imagined "Gran Turismo" at the Northeast Astronomy Forum (NEAF) on April 18, 2015. The triplet lens is the same extraordinary quality that you have come to expect

The Mach1GTO German Equatorial mount is recommended for visual observation or astro-imaging. The unique quick-and-easy daytime polar-alignment routine makes it ideal when setting up for star parties and public outreach. 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 the mount with your mobile smart device.
