Its objectives use SD (super-low dispersion) glass, which suppresses chromatic aberration for a clear, high-contrast view with very little colour bleed.\u003c\/p\u003e\u003cp\u003eThe eyepiece section is angled at 45°, so you can observe high in the sky - even near the zenith - in a comfortable position. It takes standard 31.7 mm eyepieces (sold separately), and Vixen recommends pairing it with the HF2 fork mount and the rigid SXG-HAL130 tripod for stability.\u003c\/p\u003e\u003ch3\u003eAt a
