1.Rugged housing prevents damage;
2.Sliding graceful and soft dual-speed focuser;
3.Ed glass (FPL51) can produce very beautiful and clear images;
4.The fully multilayer coated lens eliminates all reflections on the glass, and it has little or no chromatic aberration at high magnification.
A telescope that deserves a good reputation
