With an aperture of 154 mm and a focal length of 1848 mm, this classic Cassegrain delivers exceptional sharpness at high magnification - ideal for observing and photographing planets, binary stars and lunar craters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The closed design keeps the optics clean, stable and collimation-proof. The long focal length makes this telescope particularly suitable for balcony use or permanent setups where you still want to do a lot of zooming with limited freedom of movement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2713 Classic Cassegrain design: sharpness, contrast and no chromatic aberration<br>\u2713 f\/12 focal ratio - perfect for lunar and planetary detail<br>\u2713 Closed tube - resistant to dust, temperature fluctuations and miscollimation<br>\u2713 Lightweight and compact - easier to handle than long refractors<br>\u2713 Works great with small CMOS cameras for high-res lucky imaging<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This telescope suits observers who prefer serious magnification without bulky tubes.
