AX103S optical tube assembly.
The three-element objective lens, which includes a centre SD glass element, delivers crystal-clear, sharp, and high-contrast images with no noticeable false colour. Additionally, the built-in field corrector lens ensures that star images remain as small as 20 microns at the edge of the imaging field. Premium AS coatings are applied to every lens surface, enhancing visible light transmission to 99.5% (for wavelengths between 400nm and 700nm), ensuring exceptional light transmission across the entire visible spectrum.

AXJ equatorial mount.
The AXJ mount, equipped with the advanced Ultimate Periodic Error Correction (VPEC) system, provides highly accurate tracking with precision of +/- 4 arc seconds or better. The VPEC operates automatically during use, ensuring seamless performance. The mount's belt drive system significantly reduces backlash and minimizes motor noise, while delivering quick and stable motor response. Additionally, the AXJ mount supports a maximum payload of 22 kg.
