TS-Optics 8" Ritchey-Chrtien Pro RC Telescope with Carbon tube

The 8" Ritchey-Chrétien is the ideal telescope for astrophotography - more stable focus through carbon tube.

• Aperture 8" / 203 mm - focal length 1624 mm - focal ratio f/8
• Hyperbolic primary and secondary mirror for very high sharpness on the optical axis and a large well-corrected field for astrophotography
• Mirrors made of fused silica for stable focus position
• 99% dielectric high-reflectivy coating on main and secondary mirror for an even brighter image
• Carbon tube - more rigidity and better focus stability for astrophotography
• Quicker cooling down thanks to open construction
• Vixen style dovetail on one side and Losmandy style dovetail on the other side
• High-quality 2" dual speed MONORAIL focuser with 2" / 1.25" reduction adapter - motor focuser optionally available
• Spacer sleeves for optimal focus position behind the focuser are included.
• RC correctors for larger sensors from APS-C upwards are optionally available
• Optional: CCD47 - 0.67x focal length reduction for photography. This is our recommendation for shorter exposure times
