TS 6" f/9 RC astrograph and travelling telescope - compact Ritchey-Chrétien telescope with 154 mm aperture and 1370 mm focal length - very well suitable for astrophotography.
♦ Aperture 6" / 154 mm
♦ Focal Length 1370 mm
♦ Focal Ratio f/9
♦ 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
♦ Quicker cooling down thanks to open construction
♦ Vixen style dovetail bar for easy attaching to suitable mounts
♦ 2" Crayford focuser with 1.25" reduction adapter and circular clamping
♦ 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 our recommendation for shorter exposure times
Better and sharper astrophotos without corrector with shorter exposure times. This is exactly what this RC telescope allows you to do with astro cameras and SLRs up to APS-C sensors. As a pure mirror system, you can even use the infrared light. You can achieve up to 25% shorter exposure times and sharper imaging than, for example, through a comparable Schmidt-Cassegrain telescope. For the use of a reflex camera without focal length reduction you need the 50mm and the 25mm extension between focuser and telescope.
The generous backfocus also allows the connection of correctors, which we recommend from the use of full-frame sensors. You can also connect a focal length reducer, thus further increasing the light intensity of the RC.
