Sometimes simplicity is the best solution. The iOptron 6x30 Finder Scope (#6151) offers a lightweight, no-fuss way to locate alignment stars, bright deep-sky objects, or solar system targets with ease. With 6x magnification and a 30mm aperture, this compact finder provides a wide field of view and enough light-gathering ability to spot guide stars the naked eye can’t see—making it a great addition to small or portable telescope setups.
The included crosshair reticle helps you precisely center your target, and the dual-ring mounting bracket keeps the finder aligned and securely attached to your scope.
Key Features:
6x Magnification: Offers a generous field of view for fast, intuitive target acquisition. Ideal for initial alignment and quick star-hopping.
30mm Aperture: Bright enough for locating most alignment stars and brighter Messier objects, while keeping weight to a minimum—perfect for grab-and-go rigs.
Optical Crosshair Reticle: Simple and effective—helps you center alignment stars or solar system targets quickly and accurately.
Finder Bracket Included: Comes with a two-ring bracket with nylon alignment screws and a standard finder base foot for mounting.
Straight-Through Viewing: Traditional reversed image (upside down, left-right reversed) common to astronomical finderscopes.
Technical Specs:
Magnification: 6x
Aperture: 30mm
Field of View: Wide, suitable for fast sky scanning
Focusing: Adjustable objective lens for reticle focus
Mounting: Includes bracket and standard finder shoe
Orientation: Straight-through optical path
Part Number: 6151
Compatibility Notes:
The finder bracket uses a standard Vixen-style foot and is designed to fit iOptron scopes with matching finder shoes. It may also work with other brands that accept standard finder brackets.
Observing Tip:
If you're using a smaller telescope or simply don’t want the added bulk of a larger finder, a 6x30 is a smart compromise. It gives you the reach and precision needed to line up targets while keeping weight and size to a minimum—especially useful for equatorial mounts where balance matters.
About Astronomics
Helping Astronomers Since 1979
For more than four decades, Astronomics has helped hundreds of thousands of astronomers explore the universe—from someone choosing a first telescope to experienced observers and astrophotographers building the system they’ve always wanted.
A lot has changed in astronomy since we opened our doors in 1979. But one thing hasn’t:
Good advice still matters.
Astronomics was built on knowing the equipment we sell, using it ourselves, and helping people choose what’s right for them—not simply what costs more. More than four decades later, that same philosophy still guides us.
When you call Astronomics, you’ll talk to real people who know astronomy, understand the equipment, and are happy to help.
Because our goal has never been simply to sell telescopes. We want to help you enjoy astronomy.
The universe is waiting. We’d be honored to help you explore it. Fred Bieler, founder of Astronomics, in our old Norman showroom.
