Observing with Evostar 120ED
The additional aperture of this telescope provides a dramatic increase in resolution and a heighten sense of seeing lunar and planetary surface phenomenon in seemingly 3D-like high-definition. Tight globular star clusters like M13 in Constellation Hercules appear like a beehive of crisp stellar pin points, star upon thousands of stars deep into the objects core. In Deep-space, rich aggregates of stars within Galaxies, Nebulas, and open clusters appear brilliant contrasted against a very dark velvet black background. The wispy, delicate, featherlike structure of dust lanes and extension of glowing gasses can be seen reaching out far beyond the object's core.
Metallic High-Transmission Lens Coatings
Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put of approaching 99.5%. The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class.
Precision 2″ Crayford Focuser is Standard
Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2″ Crayford rack & pinion focuser-assembly. This focuser offers fine and ultra-fine focusing adjustments.
Light-Baffled Optical SystemsThe objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
Tube Materials
The optical tube material is rolled steel, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminium painted white, or black.
Telescope Tube Attachment Hardware
The optical tube comes with attachment hardware that allows it to be securely fastened to any Sky-Watcher mount. The quick-release tube rings provided with Evostar 120ED SCHOTT are cast-aluminium, painted white.
