Apochromatic telescope 304mm f/4 astrograph for astrophotography is the ultimate light cannon for deep-sky enthusiasts. With a 12-inch (304 mm) aperture, a fast f/4 ratio, and high-quality mirror coating, this telescope delivers stunning results with short exposure times even under moderate sky conditions.
The combination of raw light gathering power, a parabolic primary mirror, and a ventilated cooling system makes this instrument ideal for astrophotographers who want to work without compromises. Whether 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 primary mirror with 94% reflection coating
✓ 2″ Crayford focuser with micro-adjustment and high load capacity
✓ Active primary 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 mount, this forms a semi-professional system ready for long nights and serious projects.
Application
- Photography of faint deep-sky objects under dark skies
- Narrowband photography with OSC or monochrome cameras
