TS-Optics CCD Reducer 2″ 0,67× - For RC

TS-Optics CCD Reducer 2″ 0,67× - For RC, refractors and Maksutov-Cassegrain

Visit TS-Optics CCD Reducer 0,67× is a versatile focal reducer originally designed for telescopes. Ritchey-Chrétienbut also perfectly suited to Celestron EHD, Meade ACF, Maksutov-Cassegrain and f/8 or slower refractors with sufficient backfocus. It allows the focal length to be reduced and the f/ ratio to be accelerated, halving exposure times while enlarging the field of view.

Highlights

• Reduction 0.67× : an RC f/8 becomes f/5.3, an f/10 becomes f/6.7 → exposure times reduced by more than 50 %.
• Simple connection 2″ standard barrel compatible with all 2″ eyepiece holders.
• M48 thread on camera side 85 mm optimum backfocus (70-90 mm usable).
• 2″ filter thread integrated on the telescope side → direct compatibility with your filters.
• Illuminated field up to 29 mm, perfect for sensors APS-C (DSLR and astro cameras).
• Versatile photo as a priority, but can be used as a visual with 1.25″ angled return.

Why use a 0.67× CCD reducer?

In astrophotography, optical speed is crucial: reducing the focal length means widening the field while capturing more signal per unit of time. With this reducer, your telescopes become brighter, your shorter exposures and your images richer in detail. It's the ideal accessory for photographing diffuse nebulae and wide-field galaxies.

Compatibility

The CCD47 is optimized for RC GSO/TS/AstroTechbut works equally well with other instruments featuring a 2″ eyepiece holder. It is particularly recommended for :

• RC excellent illumination and correction up to APS-C.
• f/8+ refractors good correction with sufficient backfocus.
• Maksutov-Cassegrain improves imaging speed.
• Celestron EHD / Meade ACF wider field and shorter exposure times.

Possible adaptations

• DSLR via M48 thread → e.g. SKM48-EOS adapter for Canon.
• CCD via T2 : TSFA2 (38.2 mm, extension) or TSM48-T2 (3.5 mm, compact for OAG/filter wheels).

In a nutshell

Visit TS-Optics 2″ CCD Reducer 0,67× is an essential accessory for speeding up your f/8+ instruments and drastically reducing exposure times. Compact, easy to adapt and optimized for RCs, it broadens your photographic field while improving the productivity of your astrophoto sessions.
