TELMU 114mm Aperture 500mm AZ Mount Reflector Telescope
$159.99 price checked August 2026
If you want to capture the night sky on your phone while viewing the moon, this is the one.
TELMU Reflector Telescope Overview
The TELMU 114mm 500mm AZ Mount Reflector Telescope is for beginners who need an entry-level mirror telescope that gathers three times more starlight than a 70mm refractor.
Small aperture telescopes often fail to resolve the surface details of planets, leaving beginners with blurry images of the moon and Mars. You need a larger light-gathering surface to see the polar ice caps or cloud bands clearly.
The TELMU Reflector Telescope provides a 114mm aperture that gathers three times more starlight than a popular 70mm refractor. This larger mirror allows you to see crystal clear craters on the moon and the Orion Nebula with much greater clarity.
We evaluated the reflector telescope options we compared to determine which models offer the best value for beginners. This review is for budget-conscious shoppers looking for a simple, no-tools-required setup for nightsky viewing.

This product is one of 15 from that pool chosen for a full review. Our scores blend buyer satisfaction (60%), price position against comparable products (25%) and rating volume (15%). Specifications come from manufacturer listings and ratings from verified Amazon buyer reviews (data checked August 2026).
The Short Answer on the TELMU Reflector Telescope
Best for: you are a beginner looking for a first telescope that can resolve lunar craters and the bands of Jupiter without a complex setup.
The TELMU 114mm Aperture 500mm AZ Mount Reflector Telescope is a solid entry point at $159.99.
- Pro: The 114mm aperture gathers three times more starlight than a standard 70mm refractor for brighter views.
- Pro: It includes a 3x Barlow lens to reach 150x magnification, which is sufficient for most stable viewing conditions.
- Pro: The included smartphone adapter allows for capturing images of the night sky in real-time.
- Con: The 500mm focal length falls short of the 1000mm threshold required for practical high-magnification planetary observation.
- Con: The 3.1 rating from 29 buyers suggests potential issues with assembly or stability compared to higher-rated models.
Don’t buy this if: you require a telescope capable of resolving fine planetary details that require a focal length of at least 1000mm.
Price assessment: $159.99 is a fair price for a 114mm reflector that includes multiple replacement eyepieces and a Barlow lens.
RecommendedOptics score: 6.5/10 (data-driven – see “How we picked” above)

What These Specifications Let You Do
High Magnification Optics
The TELMU Reflector Telescope provides 150x magnification using the included 3x Barlow lens and Plossl eyepieces. This 150x limit is enough for most sky conditions because it balances power with brightness. You can see crystal clear craters on the moon and cloud bands on Jupiter without the image becoming a blurry mess.
The 500mm focal length falls short of the 1000mm focal length threshold where high-magnification planetary observation becomes practical without extreme chromatic aberration. Because this telescope does not reach that threshold, you should check the specific planetary targets you want to view to see if the 500mm focal length provides sufficient detail for your needs.
Easy Tool-Free Operation
The TELMU Reflector Telescope allows for tool-free operation, which simplifies setup for beginners. The mount adjusts from 29.9 inches to 46.6 inches to accommodate different observational positions. This range makes the telescope suitable for both kids and adults to use without needing a complex assembly.
Real-Time Sharing Capability
The TELMU Reflector Telescope includes a free smartphone adapter for real-time sharing. This allows you to capture and share images of the night sky directly from your device. Because the telescope includes the adapter in the package, you can begin sharing observations immediately without purchasing extra accessories.

How the TELMU Reflector Telescope Compares to Alternatives
The TELMU Reflector Telescope provides a 114mm aperture that gathers three times more starlight than a standard 70mm refractor telescope, offering a larger and sharper field of view.
- The TELMU Reflector Telescope costs $10 less than the Cassini 800mm x 80mm Reflector Telescope.
- The Tasco Luminova 675 x 114mm Reflector Telescope costs $10.04 less than this model.
- The Celestron Astro Fi 130 Wireless Reflecting Telescope costs $19.96 more than the TELMU Reflector Telescope.
- The Carson Red Planet Series RP-100SP costs $23.54 more than the TELMU Reflector Telescope.
- The HSL 76mm 700mm Reflector Telescope costs $30 less than the TELMU Reflector Telescope.
If you require high-magnification planetary observation, choose the Celestron Astro Fi 130 Wireless Reflecting Telescope because the TELMU Reflector Telescope falls short of the 1000mm focal length threshold required for that level of detail.

Value for Money
The TELMU Reflector Telescope is priced at $159.99, which sits $3 below the $163 average of the similar reflector telescope products we compared. At this price point, you receive a 114mm aperture and a 500mm focal length, which gathers three times more starlight than a 70mm refractor. However, the 500mm focal length falls short of the 1000mm focal length threshold where high-magnification planetary observation becomes practical without extreme chromatic aberration.
This is a viable first telescope for a beginner because it includes 1.25″ Plossl eyepieces and a 3x Barlow lens to reach 150x magnification. Because it lacks the 1000mm focal length needed for high-detail planetary work, it serves as a gateway to the hobby rather than a professional-grade tool you would need to replace to see fine surface details on planets.
Where this sits in the buyer data: Among the 25 products screened for this category, this one’s 3.1 rating places it #24, on 29 ratings – below the 37-rating median of that group, so treat the average as less settled than its comparables. On price it undercuts 27 of them.
