Comparison
The Gskyer 70AZ edges ahead here, though this is closer than the small score gap suggests. Both 70mm refractors share nearly identical apertures and weights, making them genuinely comparable options for budget-conscious observers. The single most important differentiator is the Gskyer's superior focal length of 400mm versus 500mm on the 70mm Aperture 500mm model.
While the longer focal length seems advantageous, the Gskyer's f/5.7 ratio actually delivers better light gathering and wider fields of view, particularly beneficial for deep sky observing and locating objects. The 70mm Aperture 500mm's f/7.1 ratio produces dimmer, narrower views that frustrate beginners trying to find celestial targets. The Gskyer 70AZ should appeal to anyone wanting practical optical performance and easier target acquisition, especially those planning regular observing sessions.
The 70mm Aperture 500mm makes sense only if budget is absolutely paramount and portability in the smallest possible package matters above optical quality. For most amateur astronomers starting out, the Gskyer 70AZ's superior optics justify the modest $33 price premium. It's the better telescope for actually enjoying the night sky rather than struggling to use it.
