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
1.25" moon and skyglow filter is a multi band pass filter transmitting a high percentage of light in the visual spectrum;the filter enhances contrast when observing brighter objects including the moon and planets
Telescope eyepiece cutting light pollution;the filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space
Description
SV48P 90mm telescope is equipped with fully coated green lenses and achromatic glass to enhance light transmission, suppress glare, and correct chromatic aberration, delivering high-contrast,True colors images. It is suited for the observation and photography of planets,Moon&deep-sky objects.
