The high relative brightness and twilight factor provide a noticeably brighter image during dawn, dusk and shaded outdoor conditions.
Ultra-Wide Comfortable Viewing Experience
The M5010 features oversized 24.5mm eyepieces and a wide 65° apparent field of view, delivering a highly immersive observation experience with improved visual comfort.
