Description
Large-aperture research imaging with optimized component mass defines the Officina Stellare RC 700/5600 Pro RC CGC Ritchey-Chretien OTA, a 700 mm true Ritchey-Chrétien optical tube with a 5600 mm focal length and listed f/8 optical ratio. Its borosilicate substrates, carbon-matrix structural rings, carbon-fiber truss, electronic temperature-compensated focus, dual Losmandy rails, thermal extraction fans, fixed mirror support, and protective shroud form a specialized platform for large-scale observatory imaging.
The 160 kg optical assembly still requires an engineered pier or mount, but the CGC configuration is intended to reduce selected structural mass while maintaining the listed optical and mechanical architecture. Installation requires careful lifting, collimation, balance, focus control, thermal management, camera integration, cable routing, and environmental protection before the system can be operated for long-exposure imaging.
Key Features of Officina Stellare RC 700/5600 Pro RC CGC Ritchey-Chretien OTA
This true RC optical tube combines a 700 mm aperture with a 5600 mm focal length, f/8 optical ratio, low-expansion borosilicate substrates, 96% reflective coatings, carbon-fiber truss, all-carbon structural rings, electronic focusing, thermal fans, dual Losmandy rails, and protective shroud.
- 700 mm true Ritchey-Chrétien optical system
- 5600 mm focal length with listed f/8 optical ratio
- Borosilicate low-expansion mirror substrates
- Hyperbolic primary and secondary mirrors
- 96% protected reflective coating matrix
- Electronic temperature-compensated focus
- Carbon structural rings and truss
- Thermal fans, dual rails, controller interface, and shroud included
Mass-Optimized Observatory Imaging
The supplied application focuses on deep-sky survey imaging and research observations requiring extreme aperture and focal length, with the CGC structure helping manage selected component mass while the complete system still demands high-capacity support, precise guiding, thermal control, camera spacing, collimation, and carefully managed observatory operation.
Why Choose Officina Stellare RC 700/5600 Pro RC CGC Ritchey-Chretien OTA
The CGC edition is relevant when a large observatory needs a 700 mm true RC system with borosilicate optics, carbon structural rings, electronic focusing, thermal extraction, dual Losmandy mounting, and an optimized component architecture for advanced astronomical survey or research imaging.
- 700 mm aperture for the listed observatory-scale application
- Carbon structural components for selected mass optimization
- Electronic focus, thermal fans, dual rails, controller interface, and shroud included
Officina Stellare 2-Year Limited Warranty
The supplied product information lists a 2-year limited warranty for this optical tube assembly, and the applicable regional warranty terms, mirror coverage, electronic focus coverage, thermal system coverage, structural coverage, registration requirements, and authorized service process should be confirmed with Officina Stellare or its authorized distributor before installation and commissioning.
