This telescope features a 204mm aperture triplet lens, which includes an H-FK61 ED (Extra-low Dispersion) element. The lens design aims to reduce chromatic aberration, providing sharper and more accurate images. The multi-coated lens surface enhances light transmission, offering better visibility of faint objects.

With a focal ratio of f/7, the telescope balances between focal length and aperture, making it suitable for a variety of observational and imaging tasks. The focal length of the telescope is 1428mm, and it has a resolving power of 0.57 arcseconds, which can capture fine details in the observed objects.

The focuser is a 4-inch dual-speed 1:10 rack-and-pinion model, designed for precise focusing adjustments. This focuser supports the addition of an Electronic Automatic Focuser (EAF) and includes an 80mm tube extension. The design also allows for two segments of the tube to be removed, providing flexibility for different viewing setups, such as using a binoviewer.

Included with the telescope are several accessories: a Losmandy-compatible plate, a carrying handle, and a finder shoe. An aluminum carry case is also provided for protection and transport.

For users interested in astrophotography, the telescope supports various configurations. An optional 0.8x field flattener is available to correct field curvature, useful for wide-field imaging. This accessory attaches via the M63x1 thread on the focuser, with M48x0.75 or M54x0.75 threads available on the camera side. The setup offers adjustable backfocus from 55mm to 88mm, accommodating different cameras and accessories. Additional adapters for M68x1 and M85x1 threads are being developed to further expand compatibility.

The telescope's tube is constructed from aluminum alloy, designed for durability and ease of handling. The overall weight of the telescope, including packaging, is approximately 45kg. The telescope comes in a white finish.

For mounting, the Airy Disk APO is compatible with several types of mounts, including the Astro Physique, EQ8 by Skywatcher, CGX by Celestron, and GM2000 by 10Micron. These mounts are recommended for their stability, essential for accurate observations and imaging.
