Comparison
The 150EQ wins overall, but the choice genuinely depends on your priorities and budget. The single most important differentiator is aperture; the 150EQ's 150mm mirror versus the AstroMaster's 114mm gives substantially better light gathering and resolving power, translating to superior deep sky and astrophotography performance as the scores confirm. The Celestron AstroMaster 114EQ suits budget-conscious observers seeking a lightweight, portable scope for casual lunar and planetary viewing from apartment balconies or frequent travel.
The 150EQ better serves committed hobbyists willing to transport a heavier instrument in exchange for serious astrophotography capability and impressive deep sky exploration. Consider portability realistically; the AstroMaster weighs 6kg while the 150EQ approaches 13.5kg, a significant practical difference. The 150EQ's fast f/4.3 focal ratio excels for wide-field observing and camera work, while the AstroMaster's f/8.8 ratio provides longer focal length for planetary detail on a tighter budget.
For most amateur astronomers seeking genuine observing capability beyond casual use, the 150EQ's superior aperture and astrophotography prowess justify the extra $55 and hauling effort. Choose the AstroMaster only if weight and portability are non-negotiable constraints.
