There is no faint purple haze of spurious color that can surround every bright object in every refractor scope in this price range. You will find that this Celestron 127 eq telescope does it all at a price that’s really amazingly reasonable for this size of telescope.

Which Are The Most Used Telescope Types?

Reflector telescope

Reflector telescopes which are open at one end and use mirrors which collect and focus light for the image.
Reflectors gather light using the mirror which is at the rear of the main tube.
For a given aperture width, these are generally of the least expensive type, but you will need to adjust the optical alignment periodically.

Refractor telescope

Refractor telescopes display the image upside down, yes upside down but this is normal for astronomical telescopes, but will be especially noticeable with terrestrial viewing
Refractors have a lens at the front of the tube, this is the type of telescope you are probably most familiar with.
While generally low maintenance, they do quickly get more expensive as the aperture size increases.

Which Optics Are provided With The Celestron Powerseeker 127 EQ? 


The Celestron PowerSeeker 127 EQ comes with two eyepieces, a 20mm giving 50x magnification while the other a 4mm gives 250x  magnification. This magnification power is capable of pulling in objects far and near with improved precision, which makes the 127 EQ an ideal reflector telescope for everyone, both beginners and intermediate users.


Meanwhile, also included in the package is a 3x Barlow lens, which works well by tripling the magnifying power of those 4mm and 20mm eyepieces.

The optical reflector lens of the PowerSeeker 127 EQ is fully coated, which lets it deliver clear visuals of the moon, with other stars, distant planets, and heavenly objects.

Also featured is an Erect Image Optics-orientation, which means that this reflector telescope can also be used on terrestrial (land) as well as for astronomical (sky) use.

First time consumers will take note however, that when the Celestron 127 EQ PowerSeeker is used for terrestrial viewing, the image that is presented will be upside down (inverted) due to its natural angular magnification.

How Do You calculate Magnification?

Magnification calculation

The magnification is calculated by the division of the focal length of the telescope, by the focal length of the eyepiece.

Thus for example 1000 mm / 5 mm = 200.

Thus with 1000 mm focal length and a 5 mm eyepiece, you have the desired 200x magnification.


The PowerSeeker 127 EQ has a sturdy equatorial mount that is perfect for object tracking and astronomical observation. Align the mount and you only turn one slow motion control to follow the planets as they travel the skies. The mount also has a collapsible Alt-azimuth mount, that is perfect for both terrestrial and astronomical use.

How Easy Is The Powerseeker 127 EQ To Use?

As the reflector telescope is designed especially for beginners and amateurs, it is packed with user-friendly features.

For starters, the quick-release dovetail attachment will let you setup the Celestron 127 EQ without using any tools, while the permanently mounted StarPointer Finderscope does allow for a really easy no fuss operation, giving a point and look functionality to this telescope.

There is also the easy to grab handle for moving and locking in place. The Alt-Az configuration is a simple two-way axis mount for supporting and rotating the instrument. A clutch feature allows for smooth and accurate flow-through shots that even the kids can do.

No-Tool Setup

No tools are required for assembly! as the Celestron wants you to see the stars…and quickly! Without the need for tools setup, the Celestron PowerSeeker telescope is ready for use with only minor assembling. Simply remove the telescope and tripod from the box, attach other pieces, insert the desired eyepiece, and celestial objects will begin to come in clearly. Helpful setup video can be easily found on the internet.

Celestron 127 EQ – The Pros & Cons


70% of customer reviews are very positive 4 or 5 stars

It’s very easy to pick out some obvious plus points for the Celestron 127 EQ PowerSeeker. The quality of the optics is top of my list, they form a solid basis for this telescope to become a faithful companion for years. The aperture size means that there is a wide range of targets for you to explore and hone your astronomy skills on.

The ease with which you can get your telescope up onto the mount and fully assembled, ready to start your adventures, is a definite plus. The Celestron 127 EQ represents a good balance between size, power and portability. The quality of the optics – the optics form a solid basis making this telescope a good and powerful astronomical companion for years and years.

The aperture size – enables you to explore as much as you want and learn more and more about astronomy

Easy Assembly – you can get your telescope ready to work in a matter of minutes, without any other tools. The first time, it will seem rather difficult, especially if you are not used to this type of semi-professional telescope, but in time, you will get used to it.

Celestron has some great videos on how to set up your scope, which will come in handy.
Great balance price, size, power and portability. This scope comes with one of the most remarkable price-quality ratio on the market.


One thing on the Celestron PowerSeeker 127 EQ Telescope that does need a lot of improvement, is that tripod that comes with the package. It is too light for the telescope, and therefore is quite unstable. A lot of adjustments are needed before making the tripod fully usable, which can be very inconvenient especially if you are excited to try out the telescope the first time.

As with any Newtonian Reflector, you will need to get used to aligning your telescope (collimation). There is no need to upgrade the eyepieces that come with the telescope right away, they are perfectly suitable and usable. However, you may well consider adding to them with some different eyepieces in time. You will most likely not often use the combination of the 3x magnification Barlow and the 4mm (250x) eyepiece. Celestron themselves say that the highest useful magnification of the 127 EQ is 300x but bear in mind that a different eyepiece with using the Barlow may be of benefit.

The telescope will require more care – again, we are dealing with Newtonian Reflector, so the primary mirror will be exposed to air and dust. This scope is quite fragile so you should take great care of it.

Upgrade on the eyepieces  We’re not talking about an immediate update, but in time, you will need to add some eyepieces to your telescope.

The 3x Barlow and the 4mm (250x) eyepiece will probably never be used. After all, the highest useful magnification is 300x but at least you have them, and you may well use them after purchasing any new eyepieces.

Would You Buy The Celestron Powerseeker 127EQ?

Whether you are looking for your very first telescope or your a more experienced amateur then the Celestron PowerSeeker 127 EQ Telescope should be a top high ranking contender. You will enjoy many pleasurable hours with finding and tracking your chosen objects through the night sky.

What are Mounts?

The Equatorial Mount

The equatorial mount used for astronomical telescopes and cameras. The mount is for instruments that will compensate for the rotation of earth, which is done by having one rotational axis parallel with the Earth’s axis of rotation.

The equatorial mount has two perpendicular axes, they are called Polar and Declination. When the polar axis is aligned parallel with the Earth’s rotational axis, objects can be easily tracked as they drift across the sky (due to Earth’s rotation) by turning just one of the slow-motion controls on the polar axis, instead of two, as is required with an alt-azimuth mount.

The Alt-azimuth Mount

An altazimuth or alt-azimuth mount is a quite simple two-axis mount for supporting and rotating an instrument about two perpendicular axes. One vertical axis and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument. Rotation around the horizontal axis varies the altitude (angle of elevation) of the pointing direction.

These mounts combine with all the other parts to make the Celestron PowerSeeker 127 EQ Telescope a very complete package for the amateur or starter astronomer.
