Antlia SOLAR 200F4 Ha CaK Newtonian Reflector Telescope

Antlia SOLAR 200F4 Ha CaK Newtonian Reflector Telescope

Description

The Antlia SOLAR 200F4 Ha CaK telescope is a Newtonian reflector specifically designed for high precision solar imaging. It enables imaging in Ha at 656 nm, CaK at 393 nm and white light by replacing the rear filter assembly, offering flexibility for solar imaging applications.

The primary mirror is made from quartz substrate with double sided precision polishing, providing excellent thermal stability. The optical surface accuracy exceeds lambda 8 peak to valley, ensuring fine detail rendering. The dielectric high reflective coating is optimized for both Ha and CaK bands with reflectivity exceeding 99 percent, without aluminum coating. This design eliminates the need for additional optical elements, maximizing transmission and preserving image quality while allowing shorter exposure times.

The Newtonian design eliminates chromatic aberration. The optimization of Ha and CaK bands through advanced coating ensures excellent imaging performance in near ultraviolet and solar applications. The absence of additional optical glass reduces thermal impact and improves transmission efficiency.

The mechanical structure is fully CNC machined from aviation aluminum with an open design that enhances heat dissipation. Two 68.5 cm plates provide rigidity and optical axis stability. A wide Losmandy dovetail allows direct mounting on equatorial mounts, while a narrow Vixen plate improves balance and serves as a handle.

The telescope integrates an iOptron iAFS 2 Inline automatic focuser, with the motor aligned parallel to the optical axis, ensuring smooth operation and precise alignment. A 2 inch Antlia dual band ERF filter is installed at the focuser to reduce thermal energy and protect downstream equipment.

The main focus photography version does not include a secondary mirror, simplifying the optical path and improving transmission efficiency and stability. This configuration is designed exclusively for solar imaging and is not suitable for visual observation.

The telescope requires user assembly. No additional information is available based on the provided data.
