Description
GSO RC 12" 304/2432 f/8 Ritchey-Chretien M-LRC Optical Tube Assembly (White) for Astrophotography
The GSO RC 12" Optical Tube Assembly (OTA) is a premier choice for astrophotography enthusiasts, delivering exceptional optical performance with its advanced Ritchey-Chretien design. This OTA is crafted for those who demand precision and clarity in their celestial imaging, offering full correction of coma and astigmatism.
Unlike traditional telescopes, this model employs two hyperbolic mirrors, eliminating common optical aberrations such as coma and astigmatism. Its lens-free design ensures freedom from chromatic aberration, making it a standout in its class.
The Ritchey-Chretien system, originally developed by George Ritchey and Henri Chrétien, provides a perfect optical setup devoid of the usual defects found in most telescopes. By utilizing mirror-based construction, the GSO RC OTA avoids the chromatic aberrations often seen in catadioptric systems.
Key Features
- Impressive Aperture and Quality: The hyperbolic mirror system ensures no chromatic aberration or coma, delivering high resolution.
- Rapid Cooling: Open design allows for cooling approximately twice as fast as closed tubes such as Maksutov and SCT.
- Dew Resistance: The absence of a meniscus makes dew condensation on optics extremely rare.
- High Contrast: The interior is equipped with baffles and is thoroughly blackened to eliminate stray light and glare.
