If you’re looking for an affordable and lightweight telescope that’s easy to assemble, the Celestron AstroMaster 70AZ might be perfect for you. This refractor telescope is part of the Celestron AstroMaster AZ line and offers good value for beginner astronomers interested in observing the moon and planets. For telescopes with a shorter focal length, you can expect a wider field of view, allowing you to see more in one shot. Most people are pretty happy with the resolution these telescopes have to offer, in addition to the many objects in our solar system that’ll bring plenty of amazement. Eyepieces Unless it’s extremely cheap and you’re willing to deal with its shortcomings, a used Celestron PowerSeeker 70AZ is probably a waste of your time and money. Alternative Recommendations

If your new to astronomy you’ll find the included SkyX – First Light Edition software to be very helpful and enjoy the entire learning process more. It contains a 10,000 object database with printable sky maps and 75 enhances images. Pros of the Celestron PowerSeeker 70AZ: The telescope features a higher focal length, and it’s a great option for those who may be interested in exploring astrophotography.The Celestron Astromaster 70az telescope has a focal length of 900mm. This gives the telescope a focal ratio of f/12.7, which makes it ideal for observing bright objects like planets and the moon. With a long focal length, the telescope can also provide good views of deep-sky objects like galaxies and nebulae. What is the aperture of the Celestron Astromaster 70az telescope? The included diagonal is an Amici design, shaped like a handle after Celestron noticed that people tend to grab the diagonal as such during product testing. It works fine and presents correct left-right and up-down images for terrestrial viewing. However, this is not really useful for astronomical viewing and the Amici prism absorbs light, making for a dimmer image at the eyepiece. Unless it’s extremely cheap and you’re willing to deal with its shortcomings, a used Celestron PowerSeeker 70AZ is probably a waste of your time and money. Aftermarket Accessory Recommendations MANUAL YOKE MOUNT: Navigate the sky with our refractor telescope. It features a yoke mount with a slow-motion altitude rod for smooth and accurate pointing. Adjust rod to desired position, then easily secure by tightening cross knob.

You can see many large celestial objects within our solar system with the Celestron AstroMaster 70az but you won’t be able to view Neptune or Pluto. Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. Overall, while there are some limitations with this beginner telescope, it still provides an excellent opportunity for anyone interested in exploring our solar system and beyond.

Main Features of the Celestron PowerSeeker 70AZ

I don’t know why most companies still send 5×24 finders. They are not helpful by any means. Same as the 3x Barlow, the lenses are low quality and extremely small. A simple, red dot finder without any magnification would be much better.

The Celestron PowerSeeker 70AZ’s mount is certainly not worthy of much in the way of praise, but it is not useless either. What you’re able to see with each telescope doesn’t vary too much and isn’t the biggest differentiating factor. The AstroMaster comes with a magnification range of 45x to 90x, and the PowerSeeker is capable of 35x to 175x magnification. It’s clear that the PowerSeeker offers more range here, but keep in mind it also has a shorter focal length. Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value. Whether you’re trying to see groups of celestial objects or specific details, you’ll want to always review the focal length of a telescope before you buy it. MagnificationThe Celestron Powerseeker 70AZ is frequently a top recommendation when people ask me what telescope they should get their kids as a first telescope. Let’s find out why. The PowerSeeker 70AZ mount is an alt-azimuth fork design that works well for both terrestrial and astronomical purposes. There are no slow-motion controls, but the mount’s tension can be adjusted via small knobs, which works well enough. The aluminum tripod legs are small and thin, but just adequate enough to support the whole scope. Overall, the mount is not my favorite, but it works well enough. Should I buy a Used Celestron PowerSeeker 70AZ? Thinking about purchasing a beginner telescope? Wondering if the Celestron Astromaster 70 AZ is worth the investment? Let’s take a closer look. It is not technically a portable telescope, but the Celestron 70AZ is light enough that you should have no trouble transporting it when necessary. On top of that, the AstroMaster 70az also comes with a 10mm eyepiece, and the PowerSeeker 70az includes a 4mm eyepiece.
