1. The secondary mirror coating adopts high anti electrolyte coating technology, with a reflectivity of up to 99.99%, greatly improving the contrast of telescope imaging, which is particularly important for planetary observation. The high reflectivity dielectric coating process is our first use on Marca OTA and also the first in the entire telescope industry. 2. The mirror body is portable and compact, making it easy to carry outside. The metal mirror body structure ensures the stability of the optical structure during transportation. 3. The main and secondary mirrors have been precisely calibrated before leaving the factory. Due to structural issues, there is no need to calibrate the optical axis again unless under special circumstances, reducing the burden on customers. 4. Standard Vixen 75 degree installation dovetail plate, compatible with mainstream brand equatorial instrument mounting base 5. Cone shaped extinction tube design significantly improves extinction efficiency compared to traditional extinction processes 6. Dual star search base design (one embedded and one exposed) facilitates users to connect more installation accessories 7. Ideal range for detailed lunar and planetary observations, while being able to distinguish bright deep space objects such as stars, star clusters, galaxies, and nebulae.
