Comparison
The Celestron AstroMaster 70AZ is the clear winner here. You're comparing a complete telescope to an eyepiece, which cannot function independently. The AstroMaster is a functional refractor with motorized tracking, while the Explore Scientific 62 Degree 26mm Waterproof Telescope Eyepiece is merely an accessory requiring a separate telescope to operate. The fundamental differentiator is that one is a complete optical system and the other is not.
The AstroMaster's 70mm aperture and f/12.9 focal ratio make it reasonably well-suited for planetary observation, scoring 42/100 in that category. The eyepiece alone cannot produce any meaningful observations without a host telescope. Budget-conscious beginners with no existing equipment should purchase the Celestron AstroMaster 70AZ. Experienced observers with an existing telescope who want a premium wide-field eyepiece for deep sky work might consider the Explore Scientific eyepiece, though this comparison is fundamentally mismatched.
For amateur astronomers making an equipment decision, the AstroMaster represents an actual entry point into the hobby at an accessible price. It offers genuine observing capability for lunar and planetary targets, making it the only practical choice between these two options.
