Sky-Watcher Esprit 150EDX Triplet APO OTA Limited Edition

Sky-Watcher Esprit 150EDX Triplet APO OTA Limited Edition

The Sky-Watcher 150mm Esprit 150ED Triplet APO Refractor is a high-end 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.

A 2-element field flattener is available separately to iron out the natural off-axis astigmatism and field curvature of the objective lens, leaving a fully corrected 42mm field of view. 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.
