The compact 80 mm F/7 Extra-Low Dispersion - ED refractor from Teleskop-Service is a solid and very transportable "Allround-Telescope" for observation and astrophotography. The well corrected optics provide an almost aberration-free image, due to the moderate f-ratio and integrated ED-glas. Use this APO-Refractor for astrophotography or for impressive observations. The good optics, the "photo-friendly" 2" focuser and the solid construction guarantee joy and success as well as fantastic experiences beneath the night sky.

The advantages of the TS 80 mm f7 ED-refractor:

• very well corrrected ED-optics - adjustable
• rigid and accurate 2" focuser - ball bearing mounted extension tube - focus adjustment via R&P mechanism
• 2" receptable with reduction to 1.25" with ring clamping and additional photo thread M54x0,75 screw connection
• Robustly constructed tube with fixed dew cap and CNC tube rings guarantee optimal mechanical stability

The Doublet ED objective:

The hand-manufactured objective is mounted in a temperature compensated cell. It consists of two lenses, one of them being a ED-Element for a good correction of chromatic aberration. We use the best possible Multi-coating of the manufacturer on each glas-air surface for optimal contrast.

The TS 80mm f/7 ED refractor is ideally suited for astrophotography:
The precise focuser and the light-sensitive optics make the 80 mm ED-refractor a good telescope for astrophotography. To correct the image field, we recommend the following correctors - they are also linked in the accessory section.

TSRED80 - focal length reduction and image field correction
This corrector is designed for the 80 mm f/7 ED and shortens the focal length to 448 mm. The light sensitivity increases to f/5.6. With a backfocus of 55 mm from the T2 thread you can connect all customa DSLR cameras and even CCD cameras. We recommend the TSRED80 for DSLR cameras with APS-C sensors and for CCD cameras with sensors up to 30 mm diameter.
