Meade ETX125 Observer Telescope

The ETX125 Observer Telescope by Meade:

Meade's ETX series has always been there for novice astronomers, providing the utmost in quality, performance, and value. These treasured scopes are among the best a novice astronomer can aspire to and are fully capable of retaining their value your entire observing and imaging career through sheer quality. Each new model in the series has always brought new improvements and enhancements, building on the legacy of their predecessors, and the ETX Observer series is the next step of that legacy!

Meade is well aware that many were excited about the 80 mm and 90 mm apertures, and are excited in turn to announce the return of the ETX 125, taking mobile astronomy to a whole new level. This large 127 mm Maksutov-Cassegrain telescope marries the portability of the ETX with Meade's premium optics. Enjoy detailed close-up views of the Moon and planets, and be amazed by the stunning views of star clusters, nebulae, and more!

The ETX 125 Observer comes equipped with Go-To technology and the top quality Audio-Star controller. This controller is the heart of the telescopes computer guided system, not only finding and tracking objects in the night sky for you, but also boasting a number of features of its own such as a 30,000+ object database, built-in speaker, and over 4 hours of of audio content that educates you about objects you observe. These features make this one of the premier choices for a computer controlled and guided system available, making learning about the night sky a fun and easy experience. Start exploring the night sky now, and behold the infinite possibilities!

The ETX 125 Observer comes to you loaded and ready for action with an array of useful accessories and additions. From the built in Flip Mirror to the red dot finder and it's mounting bracket, each accessory packaged with this scope is of great use and greater quality! The Flip Mirror lets you use an eyepiece and a camera simultaneously, which is good because this scope isn't just perfect for imaging- it comes with a pair of stellar quality eyepieces! These eyepieces are the 9.7 mm and 26 mm Series 4000 Super Plossls from Meade, 1.25-inch eyepieces that are well worth putting to use. The internal 90-degree diagonal makes for a more comfortable viewing position for you, the user- a convenience that is sure to be appreciated. The red dot finder can easily be mounted with the included bracket and makes for accurate and reliable guiding. When used in conjunction with the flip mirror, you can actively guide your scope while having your camera ready for your needs at the same time. The ETX 125 Observer also comes with a compass and bubble level that makes setup and alignment quick and easy. And all of this is mounted atop a steel field tripod with a built in EQ tilt plate, a stable and reliable platform to mount your system a top without any worries. This stable tripod is perfect for the telescope it is being sold with, just like the rest of these accessories. As a whole, the synergy of each part creates a truly splendid product!

Ask a Question
  • Does the ETX come with an adapter for 2" eyepieces, or is that something that needs to be bought separately.

    Only 1.25" eyepieces can be used with the ETX 125.

  • Does it come with a front lens cover? And would the cover be metal or plastic?

    The Meade ETX125 does come with a front lens cover. The cover is plastic.

  • Does this have electric focus control? Or is that an option?

    The Meade ETX125 does not come with electric focusing. There are ways of motorizing the focus. I would look at the JMI Motofocus for ETX telescope (JM-MFETX).

  • Being that this is a 1900mm f/15 scope, are there any focal reducers available that will fit this OTA for occasions when a wider field of view is desired?

    In the past, some customers have used a Meade f/6.3 SCT focal reducer with a third party ETX to SCT visual back adapter, but this was mostly for imaging at F/9. It is unclear whether you could reach focus with a 1.25" diagonal after such a reducer.

  • Is GPS built in?

    The Meade ETX-125 doesn't have WiFi built in. You can get the Meade Stella WiFi Adapter which will work for this telescope.

  • Does this scope give you a true image or reversed image when viewing through the provided eyepiece? Can a 45 degree eyepiece be attached if needed to provide a true image?

    Thank you for your inquiry. The ETX 125 Observer gives a mirrored image (left is right, and right is left). To get a corrected image, you can purchase the Meade #932 45 prism. This will thread to the back of the telescope, and it has an eyepiece holder wh

  • Will the Stella Wi-Fi Adapter work with the ETX125

    Yes, the Stella will work with the ETX125 Observer and any Audiostar-controlled telescope. Please contact us if you need additional information.

  • is there a solar filter available for the MEADE ETX125

    Yes, you can use any front mounting white light solar filter with an inner diameter (ID) of about 6.00" from Astrozap, Baader, Spectrum, or Thousand Oaks.

  • can the finder be replaced with a real finder?

    Unfortunately, there are no other finders that fit the mounting pattern for the red dot finer on this scope at the moment. You will only need the finder to get through the 2 star alignment, and then the scope's computer can take over.

  • Will the MEADE ETX125 track the ISS

    Tracking satellites like the ISS is possible, but it can be very tricky. It helps to connect your telescope to a computer so that you can download the latest ephemerides. You also will want to be set up just past late twilight or right before dawn to ha

  • Does the etx125-Observer telescope keep location, and update time and date while switched off between observing sessions?

    There is a setting on the audiostar hand controller that will allow you to save your time, date , and location. There is a park position that allows you to turn your telescope off then come back to it later and it saves the information. If you don't put t

  • Past versions of the ETX-125 had optics which were coated with Mead's UHTC coatings. I see there is no mention of it with regard to the current ETX-125 Observer. How do the Observer's "Premium Multicoated Optics" compare to the UHTC coatings that were use

    It's effectively the same coatings as UHTC at this point. Meade stopped stressing the UHTC coatings in advertising years ago when they stopped offering a non-UHTC option. It costs the factory less to have better coatings on all of their scopes than to

  • How does the performance of this scope compare with its older version ETX-125? and the new StarNavigator NG 125 Is the internal optical tube essentially the same? Secondary baffle?

    Maksutov-Cassegrains generally have consistent excellent performance due to their optical surfaces typically being nearly all spherical. This scope will hold up well against an older model. Both the ETX and Star Navigator 125 scopes share the same optic

  • The motor assembly still contain plastic gears or are they metallic now?

    Thanks for asking. The gear sets are metal in the ETX125.

  • What is the weight and size of the Optical assembly and weight of tripod alone?

    Good afternoon and thanks for asking. The tube weight and mount is 15 lbs. The tripod weighs 10 lbs. The drive motors are upgraded from the ETX90.

  • Is a hard case for the optical tube/fork mount included?

    In an effort to minimize the cost of the ETX125 Observer while maintaining quality, Meade will be selling a semi-hard luggage case as an optional accessory for this scope.
