When you're just starting your journey into astronomy, it’s easy to wonder if a 30mm telescope is enough to stargaze and capture the magic of the night sky. After all, those tiny telescopes can look like toys compared to larger models. But don't dismiss them just yet—they have their place!
In this post, I'll share my thoughts and experiences with 30mm telescopes, who they’re for, what you can (and can’t) see with them, and whether they’re worth the investment.
The Basics: What is a 30mm Telescope?
A 30mm telescope refers to one with an objective lens or mirror 30mm in diameter. This is considered an entry-level or even a "beginner" telescope. It's small, lightweight, and portable—making it an attractive choice for young astronomers or anyone dabbling in stargazing for the first time.

Pros of a 30mm Telescope:
Affordability: These telescopes are very budget-friendly. Some models cost less than a dinner date!
Portability: Their compact size makes them easy to carry on hikes, camping trips, or even to your backyard without hassle.
Great for Kids: A 30mm telescope is perfect for introducing kids to astronomy. It’s not intimidating, and they’ll love exploring with it.
Cons of a 30mm Telescope:
Limited Viewing Capabilities: A 30mm aperture is small, which means it gathers less light. You’ll mostly be able to see bright objects like the Moon and maybe some planets like Venus or Jupiter, but details will be minimal.
Low Magnification: Don’t expect to see deep-sky objects like nebulae or galaxies—they’re simply too dim for a 30mm telescope.
What Can You See with a 30mm Telescope?
Here’s the fun part. While you won’t be exploring distant galaxies, you can still enjoy some celestial wonders:
The Moon: Craters and surface details look stunning even in a small telescope.
Bright Planets: Jupiter’s moons or Saturn’s rings might be barely visible under ideal conditions.
Star Clusters: Open clusters like the Pleiades can look beautiful through a 30mm lens.

That said, if you’re hoping to dive deep into the cosmos, you might outgrow a 30mm telescope quickly.
Is a 30mm Telescope Right for You?
So, is a 30mm telescope good? The answer depends on your goals:
For Beginners or Kids: Absolutely! It’s a great way to dip your toes into the hobby without a big upfront investment.
For Experienced Astronomers: Probably not. You’ll find its capabilities too limiting.
If you’re on the fence, consider whether you want to use it casually or are ready to commit to a more powerful telescope.
Recommended 30mm Telescopes
If you’re interested in trying one out, here are a couple of good options I’ve come across:
OP - TEL-30300 – This one is affordable and comes with a basic mount and eyepiece.
ECOOPRO – A slightly higher-end 30mm telescope with better optics.

Final Thoughts
A 30mm telescope can be a fun and accessible way to start your stargazing journey. It’s a good fit for kids, beginners, or anyone looking for a lightweight, portable option. But if your goal is to see galaxies or intricate planetary details, you might want to invest in a telescope with a larger aperture.
Ultimately, whether a 30mm telescope is “good” depends on what you expect from it. If you’re okay with its limitations, it’s an excellent first step into the fascinating world of astronomy.
Happy stargazing!
