Comparison
The 150EQ wins overall, but "it depends" on your priorities. The single most important differentiator is aperture; the 150EQ's 150mm mirror versus the PowerSeeker's 127mm delivers substantially more light-gathering power and resolving ability, directly translating to better deep sky and astrophotography performance. The Celestron PowerSeeker 127EQ suits observers prioritizing portability and affordability on a tight budget, offering decent planetary views despite its limitations.
The 150EQ is the choice for serious amateur astronomers willing to accept a heavier scope in exchange for genuine astrophotographic capability and superior deep sky observation. If you plan deep sky viewing or astrophotography, the 150EQ's 71/100 astrophoto score and 57/100 deep sky score justify the extra investment and weight. If you're purely casual with limited space or transportation, the PowerSeeker's $116 savings and lighter 5.9kg mass matter more than incremental performance gains.
However, the 150EQ's superior optical performance and better overall score make it the more capable long-term instrument for growing your hobby. Choose the 150EQ unless portability is genuinely limiting.
