Telescope Types

For a hobby, sometimes we can spend quite much but the satisfaction of having an item that we want so much can be indescribable as you see the result of those hard works. If you are here it means you are attracted to astronomy; the vast room that humankind is not capable of observing properly yet. For those who are interested in celestial and terrestrial objects that are present further away from our earth, a telescope will be a must have.

  • Refractor

Telescopes are designed to magnify or bring the object closer to observe or see but there are few of them to decide. If this is your first telescope or first time interested in the hobby, there are 2 main types and 1 hybrid telescope. The first telescope is called a refractor and uses two pieces of lenses to capture the light and this is what a traditional telescope looks like or the general population idea when you mention the device in daily conversation.

It is very popular among lunar and planetary observers because of the crisp and high contrast images that can also take high magnification as well. If your goal is the finest image, this type gives the finest images possible with the given aperture.

  • Reflector

After refactor comes reflector which is less familiar for the general population and if someone mentioned Newtonian, this is the type that they are talking about as it is invented by Isaac Newton. Instead of using lenses, a refractor is using a mirror to gather and focus light, designed with a specially curved concave or dish-shaped primary mirror in the bottom end of the device. Moving up there is a diagonal secondary mirror that directs the light from the primary to the side of the tube to meet the eyepiece.

Many beginners or budget shoppers often go with this type because they can give the most aperture in a fairly low price range as well as the only type of telescope that shows users correct-reading images rather than a mirrored image. However, since the mirror is not installed in a solid position, hence the need for periodic readjustment.


If you are confused about which to choose, there is another type that combines both main types called catadioptric or compound telescope. It uses both lenses and mirrors to form an image while the biggest benefit is that the unit is very compact. The tubes are usually only measured at two or three times as long. Another is you can maintain a large aperture, powerful telescope without the bulk. What’s not so good is you will still need to do optical collimation.

About Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ

Just like everything else, we advise you to choose based on which sits best in your application or preference as all of us have different opinions on which is better. After deciding the type don’t forget to also list down the specification or how you want the unit to be so then we can shop quickly. Deciding based on the budget is also great as in most cases price reflects well on the product yet, it doesn’t mean that cheaper options are all bad.

Chances are there are a lot of budget telescopes, mainly on the reflector type which are amazing for the price point and very well-built because as any device, the material and components are necessary to ensure best performance. When you browse among reliable telescopes out there, Orion and Celestron are two familiar names to check out. These brands often being the first choice for beginners and enthusiasts for how many models they carry in the catalogue, and how diverse their price range is.

If this telescope is meant for enthusiasts who are willing to spend a little bit more, slightly above the entry-level top units, then you need to check Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ. These two are not the cheapest you can buy in the market and if you want to shave the budget, we do think Celestron AstroMaster 114 will be a more ideal option. However, performance wise, they are not compromising even though the costs are fairly low.

In today’s standard 130mm telescopes like these two are considered to be small and more of a fun option to enrich your life or to play around but as long as it gives you a good experience, we should pick anything that matches our interest. In general this size will be able to capture the objects on the Messier catalog while the global clusters will also mostly be viewable. If you want to see the brighter galaxy it can be seen but will be featureless.

Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ Design

These Newtonian telescopes are very light and if you are going to carry it to places, make sure to use a case to protect the sensitive optics but, Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ are still equally very light. What we are not very fond of is the huge tube itself yet, they are still manageable in most cases. As you can see on the sample picture above, they are very much similar to each other and just like any refractor out there; with a black tube and all black fashion.

Since these models are using equatorial mount, they may not be very ideal for smaller children to assemble alone. They are very identical including the width and the length of the tube itself which is 24-inch. You will get everything in the box from the main tube, mounting mechanism, a pair of eyepieces, and the tripod. Note that both will come in pieces so we need to put them together and align the mounting before first use.

Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ Specification

Moving further, let’s see what Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ can offer. Starting from the aperture first, as the name suggests, they are a 130mm or 5.11-inch type of telescope. The focal lengths are also very similar in both models which is 650mm, making them better if you want to see a wider area instead of pinpointing it at something. The focal ratio itself is f/5, and you will have two eyepieces in the box for different viewing experiences.

As you may already know eyepiece is rated in millimeters and the smaller they get, the bigger as well its magnification. There is a little bit of difference between the two telescopes as SpaceProbe carries 25mm with 26x magnification and 10mm with 65x magnification while on the other hand AstroMaster has 20mm with 33x magnification and 10mm with 65x magnification. Unfortunately, no barlow lens is included in these affordable Newtonian so you may want to purchase it together with the telescope.

Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ Performance

No matter how good Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ sound like, the most important part is their performance. But, worry not because both of them are equally amazing and we are surprised on how well they work despite the price point. For a tip, you can get a better view of the moon with a barlow and moon filter which improves the experience so much. However, out of the box they are reliable, you can see the moon and its craters very closely with great details.

For the more sophisticated Jupiter, while you can’t see its moon in detail, this planet is easily visible with any of these telescopes and you can tell Saturn as well but using the eyepiece they come with, this planet looks very blurry unless you put barlow lens which should be able to magnify the image further.

Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ Finder

The last part we want to talk about is the finder and for some reason, Celestron cheaper models often have an issue in this side while Orion did a good job and make its finder actually useful. The finder doesn’t track objects reliably and somehow it only pointed to the general area even after calibration, making it less useful despite the convenient purpose. It is probably less fine tuned and if you plan to locate distant objects, this finder may not be able to do the job.

Orion SpaceProbe 130ST vs Celestron AstroMaster 130EQ 

Orion SpaceProbe 130ST and Celestron AstroMaster 130EQ are very similar to each other with similar price points as well. Performance wise, these devices are amazing for the price point out of the box and if you are mostly seeing planets or clusters, we do think they are very amazing already, moreover, when added with the barlow lens which we do recommend to get. What’s different is how the finder of Orion works better than Celestron that seems to be less fine-tuned and not as useful.
