Omegon Pro RC 304/2432 Truss Ritchey-Chretien OTA

Description

Featuring an open-frame carbon fiber truss architecture and a massive 304mm (11.97 inches) quartz optical core, the Omegon Pro RC 304/2432 Truss Ritchey-Chretien OTA observatory-class telescope delivers 0.38 arcsecond Dawes resolving power. Designed in Germany, this 2432mm focal length f/8 astrograph reaches magnitude 14.2 for heavy deep-sky multi-wavelength research.

The Omegon Pro RC 304/2432 Truss Ritchey-Chretien OTA incorporates hyperbolic primary and secondary quartz mirrors with near-zero thermal expansion and 94% enhanced reflective aluminum coatings. Its open truss structure combines carbon fiber rods with CNC-machined aluminum clamping blocks, keeping total weight at 24.00 kg (52.91 lbs). Equipped with a decoupled primary mirror cell, dual Losmandy dovetail bars, and a 3-inch rack and pinion focuser, it ensures unyielding optical alignment.

Key Features of Omegon Pro RC 304/2432 Truss Ritchey-Chretien OTA

Crafted for observatory-scale deep-sky astrophotography, this 12-inch Omegon Pro Truss Ritchey-Chrétien OTA pairs zero-expansion quartz optics with an open carbon frame. Its rapid thermal equalization, decoupled primary mirror cell, and 3-inch rotating focuser deliver pinpoint star fields across large camera sensors.

• 304mm (11.97 inches) aperture with 2432mm focal length and versatile f/8 optical speed
• True Ritchey-Chrétien optical design with dual hyperbolic quartz mirror substrates
• Enhanced multi-layer aluminum optical coatings achieving 94% enhanced reflectivity
• 150mm planar secondary mirror obstruction (49.34% diameter, 24.34% area)
• Open truss architecture combining carbon fiber rods and CNC aluminum clamping blocks
• 3-inch heavy-duty dual-speed rack and pinion focuser with 360-degree field rotator
• Primary mirror cell decoupled from focuser base with push-and-pull collimation hardware
• Dual Losmandy-style dovetail plates, stray light fabric shroud, and extension ring set included

12-Inch Open Truss Architecture & Rapid Thermal Equalization

The open carbon truss design instantly equalizes mirror temperature gradients, eradicating internal tube currents. With an aplanatic two-mirror prescription that eliminates coma and spherical aberration, this 12-inch Omegon Pro RC supports magnifications from 43x up to 608x.

3-Inch Heavy-Duty Focuser & Decoupled Primary Cell

Observatory imaging with heavy camera arrays requires an isolated optical platform. The Omegon Pro RC 304/2432 Truss features a primary mirror cell decoupled from the focuser base, preventing drawtube weight from altering mirror collimation. Its 3-inch rack and pinion focuser includes a 360-degree field rotator for effortless photographic framing.

• 3-inch heavy-duty dual-speed rack and pinion focuser with integrated 360-degree rotator
• Primary mirror cell decoupled from focuser base with push-pull collimation screws
• Dual Losmandy-style dovetail plates and custom stray light fabric shroud included

Omegon Pro RC 304/2432 Truss Warranty

The Omegon Pro RC 304/2432 Truss Ritchey-Chretien OTA is backed by a 2-year limited warranty against material and manufacturing defects. The complete package contains the 304mm truss RC OTA, 3-inch heavy-duty focuser, dual Losmandy plates, stray light fabric shroud, focuser extension ring set, and step-down adapter collar blocks.
