The Sky-Watcher 120mm Esprit 120ED Triplet APO Refractor is a high-end yet portable instrument for astro-photographers seeking quality images that only a telescope of this size and optical design can produce. It's also ideal for extended visual observations of deep-space objects due to its remarkable contrast and light gathering ability.

The air spaced apochromatic triplet lenses use the remarkable Ohara FPL-53 ED (extra low dispersion) glass, with exceptional colour correction over the entire visible spectrum there is no chromatic aberration even on bright objects! Knife edge baffles reduce internal reflections and increase contrast, helping to bring out faint structure in deep sky objects.

Designed with photography in mind, it sits on two tracks above and below the barrel to prevent flexure with a heavy camera attached, and is fully rotatable to perfectly frame a target on the sensor.

  • 120/840 Apochromatic Refractor
