“I’m pleased to report that the Esprit 120 really performed.”

“I compared its performance with high-end Officina Stellare and Astro-Physics 105mm and 130mm apos employing similar premium glass. Even at high magnification with a 3mm eyepiece, star images appeared just as sharp,aberration-free and colourless as the best.  I was Impressed.”

“it exhibited none of the aberration oddities I’ve seen in some test telescopes, effects created by cold temperatures pinching optics.”

“…the Esprit 120’s performance matches the best in the business at a competitive price…”

“Sky-Watcher’s Esprit refractors become very attractive options for anyone looking for the best.”

Sky-Watcher Esprit 120ED APO Refracting Telescope

Esprit 120ED and 150ED Super APO refractors have a doublet field flattener to get a flat field and minimize aberration and distortion. Their M48 adapter for cameras assure larger clear aperture than M42 adapter to reduce halation as much as possible. Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image. 

Main Features:
- Premium optical materials
- Short focal length and full frame corrected focal plane
- Excellent field flatness
- Precision linear power focuser is standard
- Metallic high-transmission lens coatings
- Light-baffled optical systems
- Telescope tube attachment hardware





















EQ6 SYNSCAN

Sky-Watcher Pro mounts have been designed for use by novices and experts alike. These mounts provide extremely high precision tracking and have built in autoguider ports. Even the most demanding experts will be impressed by the capability of these mounts for astrophotography.

For novice users the user-friendly menu allows automatic slewing among 42,900 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The SynScan Hand Control also has the ability to connect to a computer via a RS-232 cable. Once the connection has been established between the computer and SynScan Hand Control, many commercially available planetarium software programs can be used to control the EQ6 PRO Mounts, They also come with features that advanced astronomers can appreciate:

• Positioning Accuracy up to 1 arc minute. Accuracy enhanced by software collimation error (mount mechanical error) compensation.
• Stepper motors with 1.8° step angle and 64 micro steps driven.
• Slewing speed up to 3.4°/sec (800X).
• Auto Guider Interface for astro-photography.
• Guiding speed selectable from 0.25X, 0.50X, 0.75X, or 1X.
• Object database containing complete Messier, NGC, and IC catalogues.
• Minimal vibration for steady long-exposure photography.
• Periodic Error Correction.
• PC compatibility.
• Upgradeable hand control via internet download.
