The most aperture per dollar, and an alignment to keep · review
Celestron PowerSeeker 114EQ (21045) review
Celestron's PowerSeeker 114EQ: a 114 mm Newtonian on a manual German equatorial mount with a slow-motion altitude rod, supplied with 20 mm and 4 mm eyepieces and a 3x Barlow.
The PowerSeeker 114EQ is a 114 mm (4.5 in) Newtonian on a manual German equatorial mount. Celestron says it shows planets, lunar craters, distant stars and the Orion Nebula, which is fair for the aperture.
The mount
The listing names a slow-motion altitude rod for following objects as they drift. Once the mount is polar-aligned, that is enough to keep a planet in view. It is compact and assembles without tools.
Eyepieces and the Barlow
A 20 mm and a 4 mm, with a 3x Barlow to triple each. The 20 mm in the Barlow is the useful planetary combination. The 4 mm, and above all the 4 mm in the Barlow, go beyond the roughly 230x a 114 mm aperture supports.
What is missing
The focal length, the coatings and the focuser type.
The 4 mm eyepiece with the 3x Barlow far exceeds what 114 mm can use
Only one slow-motion control named

What observers ask about this one
Is the 3x Barlow useful?
With the 20 mm eyepiece, yes: it gives the equivalent of a 6.7 mm, a planetary power. With the 4 mm it gives an equivalent 1.3 mm, far past the roughly 230x a 114 mm aperture can show.
Which eyepiece will I use most?
The 20 mm, for finding and for the Moon, and the 20 mm in the Barlow for planets. A 10 mm eyepiece would fill the gap.
AstroMaster or PowerSeeker?
The [AstroMaster 114EQ](/reviews/reflector-telescopes-celestron-114eq-family/) names its coatings and has slow motion on both axes, for $140 more on November 7, 2026.
