  • Sky-Watcher 100ED f/9 telescope optical tube
  • Ideal for deep sky photography and planetary observation.
  • Includes 10:1 Crayford focuser (best sharpness adjustment)
  • It comes with many accessories and a hard carrying case.

A 100mm refractor captures 56% more light compared to an 80mm refractor, allowing the Sky-Watcher Black Diamond 100ED to provide excellent results in planetary observation.

To obtain the valuable "APO" qualification, a refractor must correct primary and secondary chromatic aberrations, inherent to all systems whose light rays pass through an optical element. In the case of the Sky-Watcher Black Diamond 100ED, a doublet composed of an ED glass element reduces chromaticism to significantly limit the appearance of colored edges on planets or the Moon. The ED glass chosen, FPL-53 (Schott), is the one that can best correct these defects thanks to a very low dispersion.

The use of multi-layer coatings on all surfaces significantly limits losses due to lens penetration, making the Black Diamond 100ED brighter and more contrasty than conventional glasses with poorer correction. The "Metallic High-Transmission" (MHC) treatment is deposited on the glass surfaces guaranteeing impressive results (transmission close to 99.5%). Thanks to its long focal ratio, f9, the Sky-Watcher Black Diamond 100ED refractor is particularly interesting for planetary observation; Don't hesitate to use high magnifications, especially if the target object is high on the horizon.

Focus is obtained using a 2" Crayford focuser (aluminum) that offers robustness and precision during focusing. A clamping screw allows focus to be maintained according to the orientation of the tube. To be consistent with the optics and provide good results in astrophotography ( where focusing is essential) the focuser of the Sky-Watcher Black Diamond 100ED has a fine reduction screw at 10:1.

To meet the needs of amateur astronomers, the optical tube is made entirely of steel. No plastic parts used! Therefore, the solidity is there and the aesthetics are especially achieved. The interior is blackened and baffled to limit stray light intrusion. Two collars and a Vixen-style dovetail are included for secure attachment to your mount. A Kodak pitch screw is placed on top of one of the collars to position a camera in parallel.
