Officina Stellare RiFast 800/3040 SGA OTA

Description

Observatories encountering severe temperature swings during deep-space monitoring rely on the Officina Stellare RiFast 800/3040 SGA OTA fast astrograph telescope optical tube assembly to maintain focal plane stability. Built in Italy with an 800mm (31.50 inches) aperture and 3040mm focal length at f/3.8, this instrument delivers 0.14 arcsecond Dawes resolving power and a limiting magnitude of 17.2.

Constructed with an ultra-low expansion synthetic quartz glass mirror core and low-dispersion flattener optics, the Officina Stellare RiFast 800/3040 SGA OTA eliminates geometry shifts in volatile outdoor tracking environments. The open carbon truss features machined clear anodized aerospace aluminum alloy rings (SGA). Finished with 96% reflective aluminum coatings, this 250.00 kg RiFast 800 SGA assembly guarantees rigid optical precision for high-resolution celestial research.

Key Features of Officina Stellare RiFast 800/3040 SGA OTA

Tailored for continuous automated survey operations in unstable thermal environments, this 800mm Riccardi-Fast astrograph optical tube assembly pairs synthetic quartz optics with anodized structural rings. It delivers fast f/3.8 light throughput, motorized secondary focusing, and active thermal extraction for uninterrupted scientific imaging.

• Synthetic quartz mirror core paired with low-dispersion flattener corrector lenses
• Multi-layer aluminum optical coating matrix with 96% protected reflectance efficiency
• High-modulus carbon fiber truss with clear anodized aerospace aluminum rings (SGA)
• Electronic secondary mirror focus drive array with internal temperature compensation
• Fixed multi-point primary mirror cell with rear axial restraint brackets
• Custom heavy-duty multi-point observatory baseplate mounting rail array
• Built-in multi-fan secondary boundary layer thermal extraction system

Zero-Expansion Synthetic Quartz Optical System

An aspherical synthetic quartz primary mirror works with an internal sub-aperture corrector cluster to create a flat, diffraction-limited focal surface. Featuring a 350mm secondary obstruction (43.75% diameter, 19.14% area), this RiFast 800 OTA operates flawlessly across magnifications from 114x to 1600x.

Robotic Secondary Focus & Boundary Airflow Regulation

Mountain observatory sites experience swift nighttime cooling that can compromise delicate star profiles. The RiFast 800 SGA OTA uses an electronic secondary mirror focus adjustment drive that responds to internal temperature compensation mechanics. Simultaneously, the integrated multi-fan secondary boundary layer thermal extraction system purges warm air pockets within the 1120mm by 2380mm assembly.

• Electronic focus controller interface hub for automated motorized secondary control
• Multi-fan boundary layer thermal extraction array for rapid optical stabilization
• Pre-drilled chassis mounting provisions for auxiliary tracker and guide brackets
