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 from Astro-Physics.
- 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.
- Optional Quad Telecompressor Corrector converts the Gran Turismo to a blazingly fast 585 mm focal length, f/4.5 imaging machine with pinpoint stars across the field!
- Optional 3.5" Prime Focus Field Flattener.
- 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.
- Fully retractable felt-lined dew shield 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.
As shown above, the 130 StarFire GTX Gran Turismo can be disassembled to fit into a case for airline transport. Note that the optional covers are attached to the components.
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.
Images below were taken by Roland Christen using the 130 Starfire GTX with the Field Flattener and the Quad Telecompressor Corrector.
