About this deal

The eyepieces are average and are to be expected at this price point. The 20mm eyepiece did seem to create internal reflections, marring the narrow true field of view of just 0.9 degrees (the Full Moon’s angular diameter is just 0.5 degrees, for comparison). The 10mm eyepiece is perhaps the best of the two, but the eye relief on both is quite poor - you have to push your eyes right up into the eyepiece cup to see anything, making for uncomfortable viewing, and almost impossible viewing for spectacle wearers. On the other hand, parabolic mirrors are considered an ideal shape design because their resulting image quality is higher than that of a spherical mirror. If you are going to go through the trouble of changing out a mirror (which you should not with this telescope) you may as well buy a new telescope for the price of the mirror. Moving on from the discussion about the AstroMaster 130EQ Starry Night Astronomy Software, let’s now shift our attention to the Celestron Astromaster 130EQ OTA Assembly.

The Celestron Astromaster 130EQ also comes with Starry Night astronomy software which can help users locate celestial objects in the sky. However, there are some limitations to this telescope. Its plastic focuser is not very durable and may cause image distortion if not used carefully. Additionally, the mount may need frequent adjustments during use. Its equatorial mount with steel legs provides a sturdy base for astronomical observations while its high-quality optics produce sharp and vibrant images that capture even subtle details in celestial objects. Anyone looking to explore our universe should definitely consider adding this telescope to their collection. AstroMaster 130EQ Starry Night Astronomy Software Júpiter es el planeta más grande del sistema solar y el quinto en orden de lejanía al Sol. Es un gigante gaseoso que forma parte de los denominados planetas exteriores. Recibe su nombre del dios romano Júpiter (Zeus en la mitología griega). Es uno de los objetos naturales más brillantes en un cielo nocturno despejado, superado solo por la Luna, Venus y algunas veces Marte.​

Celestron markets this telescope as multipurpose due to this eyepiece, but I don’t think it was a good idea. However, it’s hard to complain when you consider the price. The eq mount is heavy and not practical to use for a beginner. Thankfully I had the ressources to build a custom Dobsonian mount out of plywood, which greatly improved the observation experience. To determine the focal ratio, divide the focal length by the aperture. Celestron Astromaster 130 EQ’s aperture is 130mm, while the focal length is 650mm, meaning it has a focal ratio of F/5. I would suggest that for now you limit yourself to a magnification the same as the mirror diameter (have a reason for this) so around the 130x area. For this you need an eyepiece of the same focal length as the f number of the scope. So if it is an f/5 scope you want a 5mm eyepiece if it is around f/8 then you need an 8mm eyepiece. This means I do not need to know the focal lengh specifically to suggest an eyepiece focal length, just get one as per the f number and you have about 130x. Its combination of affordability and ease of use make it a great choice for beginners looking to explore all that our universe has to offer. What can you see with the Celestron AstroMaster 130EQ?

The telescope comes with two eyepieces (20mm and 10mm), a finderscope, and an equatorial mount with steel legs that make it easy to set up and align. Even if you are unfortunate enough to get a sample with mediocre to poor optics, the Celestron AstroMaster 130 can show you a lot of deep sky objects, provided you obtain a better low-power eyepiece than the one included with the telescope. The brighter open star clusters and nebulae such as the Orion, Lagoon, and Swan will look fantastic with half-decent skies. Some of the bright galaxies, such as Andromeda, M82, and M64, will show their dust lanes, and under really dark skies, M51 and M101 might just reveal their spiral arms. I opted for the parabolic lens of 130P over having a motorized version. Doesn't appear to come with a 2x Barlow however I've seen posts that indicate it wouldn't be worth much anyway. Next investment will be eyepieces no doubt and could do with a recommendation on a Barlow suitable for a 5.1" f/5. Not sure whether to get a 2x or 3x.

What are you buying?

The Astromaster 130 EQ is a good value for the money and an excellent choice for beginner and experienced stargazers. But at times, getting the correct information can overwhelm many intending buyers. The Apertura DT6 offers a significant boost in aperture, much better build and optical quality, superior accessories, and a stable, easy-to-use Dobsonian mount. As some users have noted, you may need to adjust some nuts on the pointer to get it to work properly. Se trata del planeta que ofrece un mayor brillo a lo largo del año dependiendo de su fase. Es, además, después del Sol, el mayor cuerpo celeste del sistema solar, con una masa casi dos veces y media de la de los demás planetas juntos (con una masa 318 veces mayor que la de la Tierra y tres veces mayor que la de Saturno, además de ser, en cuanto a volumen, 1321 veces más grande que la Tierra). También es el planeta más antiguo del sistema solar, siendo incluso más antiguo que el Sol; este descubrimiento fue realizado por investigadores de la universidad de Münster en Alemania. We also slewed to Jupiter, which dazzled at magnitude -2.34 in the south. We pushed the AstroMaster 130EQ toward our target with ease, and are pleased to discover that the mount moves quite smoothly, with no drooping or huge amounts of resistance. At a magnification of 33x, a white disk and Galilean moons – Io, Ganymede, Europa and Callisto – is visible, but upping the magnification to 66x brings the storm systems into view.

I personally find (as other do) an 8mm eyepiece is just about right for planets. 5mm is also good. If using 8mm, you may use a 2x barlow which gives you 4.5mm. This could be pushing the scope limit a bit......but not by much and it works (i have a similar spec scope). Celestron Astromaster 130 EQ used to come with a parabolic mirror in the early days. But now, it is shipped with spherical primary mirrors only. Whether you are a beginner or an experienced stargazer looking to experience the wonders of the night sky, the Celestron Astromaster 130 EQ is an excellent choice for exploring the cosmos. The optical system consists of a spherical mirror that reflects incoming light to form an image at the focal point, where it is viewed through an eyepiece. While a spherical mirror produces images with some distortion due to off-axis light, Celestron has improved image quality by adding a secondary parabolic mirror to correct the distortion. The Zhumell Z130, like the Heritage, offers superior accessories, optics, and a simpler mount than the 130EQ but with a closed tube design.Accessories include a 20mm and 10mm eyepiece, a smartphone adapter, T-Adapter/Barlow lens, and a finderscope. The two eyepieces offer different magnifications for low and high powered views. The 20mm has a built-in erect image corrector. The Barlow & T-Adapter can be used as a 2X Barlow right out of the box. Insert any 1.25” eyepiece into the chamber and you’ll enjoy double the magnification, while retaining all the eye relief of the inserted eyepiece. Additionally, this telescope comes with a 20 mm eyepiece that provides a wide field of view and enhances the user’s viewing experience by making it easier to locate celestial objects. With its powerful magnification capabilities, users can explore deep space objects such as galaxies or observe details on planetary surfaces like Jupiter’s Great Red Spot. The Celestron Astromaster 130 EQ is a popular choice among the well-known Astromaster line of telescopes and for a good reason. This telescope is affordable, easy to use, and delivers crisp, clear images of astronomical objects. It might be possible to use a Barlow lens to extend the focal point out to where it might work. But a 2X Barlow lens is like a 2X teleconverter and it makes the scope have a 2X longer focal length and also 1/4 the amount of light. Because of this, I don't really like to use them.

Its lightweight design makes the scope easy to transport, making it an excellent choice for both on-foot and vehicular transportation. Setting up and using the AstroMaster 130mm telescope is a hassle-free process, making it a great option for beginners. You’ll be ready to observe the night sky within a few minutes of unboxing. From my welcome post I got my 5yr old son an Astromaster 130EQ for Christmas. We’re loving using it so far when the weather is right. We live in the NT, Australia so it’s very easy for us to get dark skies but it’s currently what we call the wet season so most nights are unfortunately cloudy. The limited use has shown me some things that may need upgrading or improving if it’s worth it. There is one other solution, and that is called digiscoping (google it) where the eyepiece is used and the camera is held in place above the eyepiece. It is actually an inferior way to attach a telescope and the IQ won't be that great. For a scope like this along with its lightweight mount, a light weight point and shoot or cell phone camera might be best.Since it is an erecting eyepiece, it means, you can use it also during the day, and the image in the eyepiece will be the correct way up.
