TS 90 mm f/5 Quintuplet Apo with full image field correction beyond full frame size format
The 90 mm f/5 quintuplett has been developed for astrophotography with large, but also high-resolution sensors as used in modern astro cameras and system cameras. The image is free of annoying chromatic aberrations and reflections with very good sharpness over the entire image field.

Link to AstrobinWith about 5.2 kg and only 36 cm transport length, the telescope is very compact and even suitable for air travel. We recommend a mount of the EQ5 class or an even more stable one as base.
Other features and benefits of the 90 mm f/5 quintuplet:
The corrector is fixed in the tube, as soon as you have focused the camera, you are automatically at the right distance for an optimal field correction. The 3.7" focuser is supplied with an extension from M63x1 to M48x0.75 with a screw-in option for 2" filters. Tilting mechanism with push and pull screws to compensate for a misalignment of the camera sensor for perfect edge stars. Every 90 mm quintuplet apo is optically and mechanically checked before dispatch at Teleskop-Service.Technical Information
