Name: Tecnosky Telescope AC 234/1800 Goliath, OTA
Brand: Tecnosky
SKU: TKG234G
Price: 7590 EUR

The huge refractor offers high contrast for the moon and planets, but especially for deep sky objects.

234 mm aperture collects a lot of light, while the relatively slow focal ratio keeps chromatic aberration to a minimum

High contrast due to lack of obstruction

Solid, deformation-free tube with internal baffles to prevent stray light

Large dual-speed focuser with rotation capability

Manufacturer: Tecnosky

Product number: TKG234G

Tecnosky Telescope AC 234/1800 Goliath, OTA

With this telescope, Tecnosky offers a refractor with a huge aperture: 234 millimetres free of obstruction means an image definition that mirror telescopes with their annoying secondary mirrors can only dream of! The air-spaced achromatic doublet shows hardly any chromatic aberration thanks to the slow focal ratio of f/8. An ideal field of application is the separation and measurement of double stars and the obstruction-free observation of fine structures on the moon and planets. We recommend using the Baader Semi-Apo Filter (see recommended accessories) to suppress colour aberrations on bright structures and increase contrast.

For photography, the refractor is recommended for deep sky observation of wider fields and photography with line filters, for example H II regions with H-alpha filters or photography with additional [O III] filters and [S II] filters (Hubble palette).

The refractor can of course also be equipped with an H-alpha filter for solar observation (see example image).

The tube of the achromatic refractor is made of three millimetres thick aluminium with internal baffles and is manufactured in Italy. The scope comes with tube rings and a dovetail bar according to Losmandy standard.

Due to the heavy (27 kg) and long tube, stationary installation is recommended, e.g., in an observatory.
