90 mm aperture; 500mm focal length; compared with 70mm and 80mm; 90mm telescope has more light input and a wider field of view; observe the moon and deep space; which is very suitable for astronomy beginners
Double speed focuser; the 2 inches rotatable double speed focuser; gear ratio of 1:10; precise adjustability for smooth operation
The focusing mount with metal interface has higher interface accuracy; guarantees the parallelism of the optical axis; and enhances the observation experience
Correct chromatic aberration; SV231 telescope filter prevents unwanted color banding in the blue spectral range; minimizes blue wavelengths in out-of-focus areas
OD＞4; the higher the filter cut-off depth; the smaller the noise and the higher the imaging contrast
