Gran Turismo 81 內部對焦設計 (WIFD) 複消色差

Set it up last night and the first thing I noticed was how sharp the stars looked even at higher magnification. The apochromatic design really kills that false color I used to struggle with. Can't wait to try it on some double stars.

The internal focus design is a game-changer—adjusting focus without shifting the telescope’s center of gravity means I can fine-tune views of Jupiter’s cloud bands without rebalancing the mount. Even at high power, the apochromatic optics deliver crisp, color-free stars across the entire field.

Finally got this set up on my mount and the internal focus design is buttery smooth — no image shift at all when fine-tuning focus. First clear night I spent two hours just scanning the Orion Nebula and the star images stayed pin-sharp across the whole field.
