The 8" f/8 Astrograph was designed for full illumination of the "35mm format" (24 x 36mm). For cameras with a small sensor, particularly most CCD cameras, no field flattener is needed. For cameras with a larger sensor we recommend the use of a field flattening lens. (Currently under development.)
Since the optical layout of the RC uses no lenses or corrector plates there is no false colour at all. Also you will not need to use an IR cut filter, thus increasing the effective light-gathering power of the instrument
How to bring a SLR camera into focus:
The RC has a generous back focus allowing to attach many accessories like e.g. off-axis-guiders, filter wheels etc. If you want to take photos with a (D)SLR camera with the focuser in a moderate position, you need the following optional accessories:
- GSRCV50: 50mm spacer, to be placed between focuser and telescope
- TSFA240: T2 adapter with 40mm extension
Optical Design: True RC (Ritchey-Chretien) with a hyperbolic primary and a hyperbolic secondary mirror. No glass corrector plates or lenses in the optical train.
Computer-optimized baffle system: The inside of the tube is lined with computer-optimized baffles for optimum suppression of stray light
Focuser: 1:10 Monorail focuser for extremely smooth focusing. The dual speed 1:10 focusing knob is particularly important for astro imaging. No image shift and up to 5kgs load capacity! The focuser accepts 2" and 1.25" accessories.
Dovetail mounting rail: A GP-style dovetail rail is mounted on the underside of the tube. It fits in all mounts that accept GP / Vixen dovetail plates
