Sky-Watcher Evostar overview

  • 1Description

An upgrade from the standard Evostar 150, the Sky-Watcher Evostar 150DX ED APO 150mm f/8 Refractor is outfitted with a larger and stronger focusing mechanism and drawtube, and a heavy-duty cradle-ring and mounting system.

The large 150mm aperture is complemented by an extra low-dispersion (ED) element set in a doublet apochromatic lens design. These two optical features make the Evostar much more precise than standard refractors, producing crisp and clear high-resolution views with limited edge distortion and accurate color representation. To easily carry heavier 2" eyepieces or full-frame DSLRs, Sky-Watcher upgrades the focuser on the DX model to a strong and sturdy rack-and-pinion style with a massive 3.4" diameter drawtube. The rack-and-pinion design provides a rock-solid platform for heavy loads, while the drawtube lets copious amounts of light through unimpeded to ensure the brightest views and fully cover even the largest imaging sensors.

A stiff and sturdy heavy-duty mounting cradle-ring assembly clamps over the OTA and lets the user adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and to help with balancing, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a large Losmandy-style dovetail plate makes it compatible with any mount head with a Losmandy-style saddle to safely carry the 22-pound OTA plus accessories. Protecting the optical tube and accessories during transport and storage, a hard aluminum carrying case is provided.

Optical Tube Assembly
  • Large 150mm aperture is especially useful for lunar and planetary, or deep sky observations and imaging
  • 1200mm focal length helps to produce a moderate magnification potential
  • Moderate f/8 focal ratio is ideal for observations and long-exposure astrophotography
  • Apochromatic doublet lens design with an extra low-dispersion element eliminates chromatic and spherical aberrations for true color rendition and without distortion across the entire field of view
  • Hard aluminum carrying case to safely store and transport the OTA and accessories
  • Rack-and-Pinion style is more sturdy and steady that other designs to carry heavier loads—such as full-frame DSLRs and imaging cameras
  • Dual-speed mechanism permits fast coarse and precision fine focusing to ensure tack-sharp views
  • Massive 3.4" drawtube permits the use of even the largest imaging sensors without vignetting while offering exceptional strength and resistance to flexing or twisting
  • 2" eyepiece holder accepts larger eyepieces and accessories for easier and more comfortable viewing
  • OTA only, mount head and tripod required for proper use
  • Stiff and sturdy heavy-duty cradle-ring assembly for dovetail plate allows the scope orientation to be changed based on mount configuration
  • Large Losmandy-style dovetail plate is compatible with any alt-az or equatorial mount with a Losmandy-style saddle
  • Weight: 22 pounds
