Celestron 21036 PowerSeeker 70AZ Telescope

Product Information

However, it struggles when it comes to deep sky objects due to its limiting magnitude of 11.7. Overall, the Celestron AstroMaster 70AZ Telescope offers good value for beginner astronomers interested in observing planets and the moon.

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? 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. The PowerSeeker mount comes with two slow motion control knobs that allow you to make fine pointing adjustments to the telescope in both Right Ascension and Declination axes, also referred to as RA and DEC.

Assuming your battery arrived with full power and with the plastic connection strip still in place, follow these steps: Similarities are important to review, as it shows what you’ll benefit from regardless of which telescope you choose. So let’s delve into them. Aperture 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.

Each telescope comes with two different eyepieces, and although they come with a slight variation in one eyepiece, they both have a 20mm eyepiece as well. Nevertheless, a 70mm aperture is more than sufficient to see many celestial objects in great detail. To some extent this can be improved with a couple of better eyepieces but I personally would probably suggest moving to a nicer telescope such as the previously mentioned Orion Astroview 90mm refractor if you find you outgrow the Celestron Powerseeker 70AZ and still want more.

The Good

You can see many large celestial objects within our solar system with the Celestron PowerSeeker 70az, but you won’t be able to view Neptune or Pluto. The PowerSeeker refractors all come with a 20mm Kellner eyepiece (45x), a 4mm Ramsden eyepiece (175x), and a junk 3x Barlow (the Newtonian scopes come with a 20mm erecting eyepiece instead of the 20mm Kellner). The 20mm Kellner is decent, but 45x is simply too much magnification for a 70mm telescope’s low power eyepiece. The 4mm Ramsden already provides too much magnification for 70mm of aperture, and its narrow field of view and low quality don’t help. The 3x barlow is entirely plastic and is utterly useless as anything more than a dust cap. Setting up the telescope is a breeze and will have you observing in no time. Even on your first time out, you can assemble the telescope and its accessories in just a few minutes. The adjustable tripod legs allow you to customize the telescope’s height or place it on raised surfaces like a picnic table. The total telescope kit is lightweight and perfect for impromptu observing sessions or transporting wherever life’s adventures take you. This particular feature may not be a deal breaker for most people, but it’s important to know whether a telescope features a mirror or lens optical design. What Can You See With The Celestron AstroMaster 70az? 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.

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. Magnification Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.

What We Don’t Like

Although it’s understandable to be interested in their differences, both telescopes also come with a few similarities that you won’t have to miss out on. At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope. We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. The aluminium tripod with the accessory tray is not much different from the aluminium trays from the other models within this range. Being made of aluminium means it’s lightweight but the overall firmness of it’s stability may be a questioning factor. The accessory tray is a nice feature to have on your tripod as it’s perfectly fitted to store the different eyepieces and accessories and have them close by at your disposal.
