Apochromatic telescope 304mm f/4 astrograph for astrophotography 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.
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.
✓ 304 mm aperture - captures more than 1800x as much light as the naked eye
✓ f/4 optics - short exposure times and wide fields of view
✓ Parabolic BK7 main mirror with 94% reflection coating
✓ 2″ Crayford focuser with micro fine adjustment and high carrying capacity
✓ Active main mirror fan for rapid temperature stabilization
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 ready for long nights and serious projects.
