Optical performance:
1. Sharp field of view: 42° apparent field of view with a clear field of view appendix, and the edge image is compact, which is especially suitable for high-power observation of planet surface details, lunar craters or decomposition of close binary stars.
2. Extinction optimization: The blackening of the edge of the lens effectively inhibits stray light, reduces internal reflection with the uncoated adhesive surface, and improves the recognition of low-contrast targets (such as the Jupiter cloud belt).
3. Same-focus design: There is no need to refocus when replacing the same series of eyepieces, and the observation efficiency is higher.

Humanized design: Humanized design:
* Filter compatibility: The 1.25-inch threaded interface can directly install polarizers, moonlight filters and other accessories.
* Professional mirror tube: The conical mirror tube abandons the traditional safety tank and simplifies the disassembly process (pay attention to telescope compatibility).

Applicable scenarios：
* Planetary observation (Jupiter Great Red Spot, Saturn's Ring)
* High-resolution lunar surface research
* Double star separation and sunspot observation (requires a filter)
