Omegon 140 mm Triplet Refractor

Apochromatic telescope 140mm triplet for astrophotography is a high-end refractor for astrophotographers and visual observers striving for maximum image quality. Thanks to its large aperture of 140 mm and a bright f/6.5 ratio, this telescope is perfect for deep-sky photography and high-resolution observations, for example of double stars or fine nebulae structures.

The high-quality FCD100 ED glass from Hoya in Japan guarantees an exceptionally color-error-free image. The triplet lens delivers pin-sharp stars and a contrast reproduction that convinces even the most demanding amateur astronomer.

✓ Large aperture (140 mm) for bright deep-sky images
✓ FCD100 ED triplet lens with exceptional color correction
✓ Suitable for full-frame cameras thanks to 3.5” focuser
✓ Robust transport case included - ideal for fixed observation site
✓ Equipped with CNC rings, GP/Losmandy rail and extendable dew cap

This telescope is ideally suited for use in a home observatory or as a fixed mount under dark skies. Thanks to the M63 thread, sturdy carrying handle/mounting rail and high mechanical precision, it is ready for professional use.

Application

• Deep-sky astrophotography under dark skies
• High resolution planetary observation (Jupiter, Saturn)
• Narrow double stars and star clusters
• Use in small observatories or fixed setups
