Apochromatic telescope 72mm quintuplet for astrophotography

Apochromatic telescope 72mm quintuplet for astrophotography is a compact top-of-the-line refractor with five lens elements, including two ED lenses, and a built-in corrector for a flat field of view. This telescope is designed for astrophotographers who demand maximum image quality in a light and mobile instrument.

With an image circle of Ø 44 mm, this telescope is fully compatible with full-frame cameras. The high-quality optics deliver color-error-free, high-contrast images - even at low aperture ratios. The built-in corrector eliminates field curvature so that even image angles remain razor sharp. Ideal for nebulae, galaxy structures and star fields.

✓ Five-part lens with two ED elements for color-pure images
✓ Built-in corrector - flat field of view up to Ø 44 mm for full-frame cameras
✓ 3″ focuser with 1:10 reduction - suitable for heavy cameras
✓ 360° rotatable focuser for perfect image orientation
✓ CNC tube with anti-reflection coating and extendable dew cap

This telescope is a dream for mobile widefield astrophotographers. Its low weight (2.56 kg) and short tube length (31.7 cm) make it easy to take with you to dark observing locations - without sacrificing optical performance.

Application

• Deep-sky widefield astrophotography (full-frame and APS-C)
• Observation of star fields, nebulae and clusters
• Compact setup for mobile astrophotography
• Also suitable for moon and planets (visual and photographic)

What you can see with it

✓ Large nebular structures such as the North American Nebula and the Rosette Nebula
✓ Milky Way fields and open clusters such as the Pleiades
✓ Moon and bright planets with sharp contrast
✓ Fully exposed image to the corners with full-frame sensor
