Tecnosky Telescope AC 234/1800 Goliath OTA

Item description:

The AC 234/1800 optics : With this telescope, Tecnosky offers a refractor with a huge opening: Obstruction-free 234 millimeters mean a selectivity that reflecting telescopes with their annoying secondary mirrors can only dream of! The achromatic doublet with air gap shows hardly any chromatic aberration thanks to the small aperture ratio of f/8. An ideal field of application is the separation and measurement of double stars and the unobstructed observation of fine structures on the moon and planets. Here we recommend using the Baader Semi-Apo filter (see recommended accessories) to suppress the color error in light structures and increase the contrast.

Photographically, the refractor is recommended for deep-sky, wide fields and photography with a line filter, for example HII regions with an H-alpha filter or photography with an OIII filter and SII filter (Hubble palette).

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

The tube of the achromat consists of three millimeter thick aluminum with inner screens and is made in Italy. The scope of delivery includes the tube rings and a dovetail bar according to the Losmandy standard.
