Sky-Watcher 9×50 erecting viewfinder: the star cluster viewfinder for deep-sky
The 50 mm lens shows much weaker stars than a 6×30, and the fully corrected image (right upright, left-right correct) matches exactly your star chart or planetarium app. This combination makes it the reference viewfinder for deep-sky star gazing: recognize the pattern on the map, see the same pattern in the viewfinder, target found.

The 90-degree angle of view keeps the posture comfortable, even right above your head. The crosshairs center your target; after that, it’s also in the main ocular focus. If you prefer to look in the same mirror orientation as your zenith mirror, then the standard right-angled 9×50 is the match.
