TS-Optics Photoline 2" 0.8x Reducer/Flattener for 70-80 mm ED Refractors belongs to the Imaging Correctors / Reducer / Barlow range. 2-inch 0.8x reducer and flattener for ED refractors around 70-80 mm aperture and approximately f/6 to f/8.

Key product details

• Astrophotographers using 70-80 mm ED refractors
• DSLR and astronomy cameras up to approximately APS-C
• Wide-field deep-sky imaging
• 0.8x reduction factor
• For suitable ED refractors around f/6 to f/8
• 2-inch push-fit connection

Product overview

The Photoline 0.8x reducer shortens the focal length of suitable small ED refractors while also flattening the photographic field. This makes the system faster and increases the available field of view.

Suitable applications

• Astrophotographers using 70-80 mm ED refractors
• DSLR and astronomy cameras up to approximately APS-C
• Wide-field deep-sky imaging

Included equipment

• 0.8x reduction factor
• For suitable ED refractors around f/6 to f/8
• 2-inch push-fit connection
• T2 M42x0.75 camera thread
• 55 mm working distance
• 2-inch filter thread on telescope side
• Corrected field up to about 30 mm according to product data

55 mm sensor spacing

The distance from the T2 thread to the camera sensor should be around 55 mm. Some telescope and sensor combinations may benefit from fine adjustment.

Practical note

Before buying, check that your exact refractor falls within the intended aperture and focal-ratio range. A universal 0.8x reducer is not automatically an optical match for every ED refractor.
