Its 760mm focal length frames large deep-sky targets, while the carbon fibre sandwich tube construction maintains focus stability at a low weight of approximately 6kg. With tight stellar spot sizes of just 4.1µm on-axis and 8.1µm at the edge of the field, the AG8 delivers sharp, coma-free stars across full-frame sensors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eFast f\/3.8 Optics: The 200mm Primary and 4-Lens Corrector\u003c\/h3\u003e\n\u003cp\u003eThe AG8 is built for speed. The 200mm primary mirror operates at a native f\/3.8, drastically reducing exposure times compared to f\/5 or f\/6 systems and allowing you to capture more data in a single night. This aggressive focal ratio is managed by an integrated 4-lens ED corrector, which eliminates off-axis coma and produces a flat field, ensuring that stars remain pinpoint across the entire frame.\u003c\/p\u003e\n\u003cp\u003eThe 90mm secondary mirror provides even illumination over the 45mm image circle, a necessary design choice for a fast, wide-field astrograph.

combines a 250mm primary mirror with an exceptionally fast f\/3.8 focal ratio to dramatically reduce exposure times. Its integrated 4-lens ED corrector produces a 50mm flat field, delivering pinpoint stars from a 3.0µm on-axis spot size to just 7.2µm at the edge of the frame. Housed in a rigid carbon fibre sandwich tube weighing approximately 12kg, the AG10 is a purpose-built instrument for serious deep-sky imagers using large-format sensors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eFast f\/3.8 Optics with a 50mm Corrected Field\u003c\/h3\u003e\n\u003cp\u003eThe core of the AG10 is its optical speed. At f\/3.8, you can capture deep signal on faint targets in a fraction of the time required by f\/8 or f\/10 systems. This speed is made usable by a sophisticated 4-lens ED corrector integrated into the optical path.

This large-aperture focuser is designed to carry heavy imaging trains, including large cameras, filter wheels, and off-axis guiders, without sagging or shifting. The 10:1 dual-speed reduction allows for extremely fine focus adjustments, which is critical for achieving sharp stars at such a fast focal ratio.\u003c\/p\u003e\n\u003cp\u003eThe 250mm primary mirror is supported by a 9-point suspension mirror cell, also CNC machined.

AG14 Optical Tube Assembly combines a massive 350mm primary mirror with an incredibly fast f\/3.8 focal ratio to dramatically reduce exposure times on faint deep-sky objects. Its integrated 4-lens ED corrector delivers a flat field larger than 50mm, producing sharp stars with spot sizes as small as 3.4µm on-axis and 4.7µm at the field edge. This 1330mm focal length astrograph is engineered for the largest modern sensors, providing professional-grade results from a precision-built instrument.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003ef\/3.8 Corrected Newtonian Optics: A \u0026gt;50mm Flat Field\u003c\/h3\u003e\n      \u003cp\u003eThe AG14's optical system is designed for one purpose: wide-field imaging. The fast f\/3.8 primary mirror gathers immense amounts of light, while the custom-designed 4-lens ED corrector eliminates coma and field curvature.

This material offers exceptional rigidity at a manageable weight of approximately 24kg and, more importantly, exhibits near-zero thermal expansion. As temperatures drop during an imaging session, the 1203mm tube length remains constant, preventing focus shift that can ruin long exposures.\u003c\/p\u003e\n      \u003cp\u003eThe 350mm primary mirror is held securely by a CNC-machined aluminum 9-point suspension cell, which provides uniform support to prevent gravitational flexure as the telescope tracks across the sky.

is an imaging instrument engineered for large-format sensors, combining a massive 400mm primary mirror with a fast f\/3.8 focal ratio. Its integrated 4-lens ED corrector delivers a flat field greater than 50mm, producing on-axis spot sizes of just 4.1µm. The entire optical system is housed in a rigid, 1320mm carbon fibre sandwich tube weighing approximately 33kg, providing the thermal stability required for consistent focus through long imaging sessions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 400mm f\/3.8 Optical System: A \u0026gt;50mm Flat Field Astrograph\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the AG16 is a 400mm primary mirror operating at an aggressive f\/3.8 focal ratio, designed to capture faint signal from deep-sky objects in significantly shorter exposure times. To manage this fast optical train, a computer-designed 4-lens ED corrector is permanently installed, yielding a corrected image circle greater than 50mm in diameter. This comfortably illuminates large full-frame and medium-format astronomy sensors, ensuring sharp stars across the entire frame.\u003c\/p\u003e\n\u003cp\u003eThe optical correction achieves spot sizes of just 4.1µm on-axis and 6.6µm at the edge of the field.

This construction minimizes focus shift as ambient temperatures change during the night, a critical factor for maintaining sharpness in an f\/3.8 system. At approximately 33kg, the tube assembly remains manageable for observatory-class mounts.\u003c\/p\u003e\n\u003cp\u003eTo accelerate mirror cooling and reduce tube currents, the primary mirror cell is equipped with three controllable fans.
