Apochromatic telescope 304mm f\/4 astrograph for astrophotography<\/strong> is an ultimate light cannon for deep-sky enthusiasts. With 12-inch (304 mm) aperture, a fast f\/4 ratio and a high-quality mirror coating, this telescope delivers stunning results at short exposure times even under moderate sky conditions.<\/p>\n\n\n\n

The combination of brutal light output, a parabolic main mirror and a vented cooling system makes this instrument ideal for astrophotographers who want to work without compromise. Whether you are capturing emission nebulae in H-alpha or photographing galaxy fields with an OSC camera, this system gets everything out of your sensor.<\/p>\n\n\n\n

\u2713 304 mm aperture - captures more than 1800x as much light as the naked eye
\u2713 f\/4 optics - short exposure times and wide fields of view
\u2713 Parabolic BK7 main mirror with 94% reflection coating
\u2713 2\" Crayford focuser with microfine adjustment and high load capacity
\u2713 Active main mirror fan for rapid temperature stabilization<\/p>\n\n\n\n

Despite its impressive performance, the telescope remains relatively compact for a 12\" reflector. Combined with an EQ6-R, iOptron CEM70, or other heavy-duty mount, this forms a semi-professional system that's ready for long nights and serious projects.<\/p>\n\n\n\n
