Key product details
- Experienced deep-sky astrophotographers
- Galaxies and planetary nebulae
- Imaging on a stable medium to large mount
- 203 mm aperture and 1624 mm focal length
- f/8 focal ratio
- Hyperbolic primary and secondary mirrors
Product overview
The 8-inch RC provides more aperture and a faster f/8 system than the smaller 6-inch version. It is particularly well suited to galaxies, planetary nebulae and smaller deep-sky targets.
Suitable applications
- Experienced deep-sky astrophotographers
- Galaxies and planetary nebulae
- Imaging on a stable medium to large mount
Included equipment
- 203 mm aperture and 1624 mm focal length
- f/8 focal ratio
- Hyperbolic primary and secondary mirrors
- Quartz mirrors
- 99% reflectivity according to product data
- 2-inch Monorail focuser with fine focus
Imaging system
For moderate sensor sizes, the RC design provides a well-corrected field. Larger sensors may benefit from an additional corrector.
Practical note
At 1624 mm focal length, tracking errors become visible quickly. Use a stable mount and a carefully tuned guiding setup.
