TS-Optics CCD47 0.67x Reducer for RC and Flat-Field Telescopes

TS-Optics CCD47 0.67x Reducer for RC and Flat-Field Telescopes – Product description

TS-Optics CCD47 0.67x Reducer for RC and Flat-Field Telescopes is intended for applications in the Imaging Correctors / Reducer / Barlow category. 2-inch 0.67x focal reducer for Ritchey-Chrétien and other flat-field telescopes to around f/8. The following information gives a detailed overview of equipment and use.

Key product details

• Astrophotographers using RC telescopes
• Flat-field systems such as suitable ACF or EdgeHD configurations
• Cameras up to approximately APS-C sensor size
• 0.67x reduction factor
• 2-inch barrel
• M48x0.75 camera connection

Product overview

The CCD47 significantly reduces focal length and focal ratio on suitable telescopes. It was developed particularly for Ritchey-Chrétien systems but can also work well with other telescopes that already provide a well-corrected field.

Suitable applications

• Astrophotographers using RC telescopes
• Flat-field systems such as suitable ACF or EdgeHD configurations
• Cameras up to approximately APS-C sensor size

Included equipment

• 0.67x reduction factor
• 2-inch barrel
• M48x0.75 camera connection
• 2-inch filter thread on telescope side
• Optimum spacing around 85 mm
• Useful range approx. 70-90 mm according to product data
• Illuminated field approx. 29 mm

Working distance

Image quality depends strongly on the distance between reducer and sensor. The generous spacing also leaves room for accessories such as a filter wheel or off-axis guider.

Practical note

Plan the complete optical path in advance. With APS-C sensors in particular, accurate spacing is worthwhile.
