Telescope Invention

Space is always interesting to observe and while not all of us are capable of going out there and see with our own eyes about the beauty of our universe, at least we can still view many from here. Of course it is impossible without a dedicated device to help you see those in further distance and hence a telescope is the first thing an astronomer, hobbyist, or just anyone who wants to get a peek of what’s out there wants to have.

Many believe that Gelileo Galilei was the first person who invented the telescope and while it still has some truth into it, the earliest document about the person who created this optic was actually a glass maker named Hans Lippershey, back then in 1608. The first magnifying device was credited to him and used to be called a “kijker” or looker which is able to magnify objects up to three times. The original design is made of concave eyepiece aligned with another convex objective lens.

Most opinion said that he was inspired by two children holding up two lenses that appeared to make a distant weather appear closer. However, there are also other opinions that stated Lippershey’s idea was stolen from another glass maker named Zacharias Jensen yet, many historians and widely, Lippershey is the one recognized as the inventor of the first telescope because of the patent he held. Zacharias actually was also creating the design at that time thus, the two people might be creating their own telescopes.

Not long after, the telescope was produced and distributed to high society around Europe. This news arrived in Galileo Galilei’s ears in which he then created his own telescope without actually seeing Han’s device. What’s even more amazing is he is also capable of improving the design and creating a telescope with significant upgrade since his version can magnify objects about 20 times. This invention then presented to Venetian Senate which then earned him the position as lecturer at the University of Padua for life.

What makes Galileo special and more popular when people are mentioning the history of telescopes is not only about his creation but also because he was the first to point it at the sky. He wasn’t the first to see the moon but the first to actually take a look at its surface and even craters with his telescope. Through this device he is able to draw the moon’s phases in detail, describe the Milky Way, discover the rings of Saturn, and even Jupiter’s moons.

About Celestron NexStar 130 SLT and 4SE

It is now 21th century and our technology has improved so much that almost anyone can have a telescope and you can have as much magnification as you want. Pictures of our planet and others in the same solar systems are readily available to enjoy from your smart device and recently we even have a better view of the famous black hole. Nowadays telescopes are very affordable, many of them are even computerized to make everything more enjoyable but still convenient.

The newest type of telescope is compound or catadioptric telescope which combines the use of a lens and mirror to achieve both benefits from both designs. This type of telescopes are often more expensive but many are also easier to use if you want a better and improved experience. Celestron as one of the most popular telescopes manufacturers carry lots of models in their catalog in which one of them is this compound model. Similar to their reflector and refractor, you can find this type of telescope in a varying price range.

Each type of telescopes usually carry their own advantages over the other as well as disadvantages and if you based this shopping on a budget, those who are planning to allocate $500 for the device may want to check two popular models Celestron NexStar 130 SLT and 4SE. The latter is actually their bestselling compound model and these two are great if you are ready to step up a bit from cheap, entry-level models like Celestron AstroMaster 70AZ.

As you may already know, these two are pretty different telescopes as the first is a Newtonian which means it uses mirrors compared to the second which is a cassegrain or Maksutov-Cassegrain to be exact. What we love from both Newtonian and cassegrain is that they are more ideal if what you want to peek at fainter objects or for those interested in deep-sky viewing but between the two, usually mirror telescopes often win in terms of performance depending on various factors and optics quality as well.

Celestron NexStar 130 SLT and 4SE Design

As you can see from the sample picture above, Celestron NexStar 130 SLT and 4SE are very short in dimension which makes them convenient if you need to bring it somewhere and try to find the perfect case or box to contain the item. The optical tube is very sturdy and doesn’t look cheap at all since they are made from aluminum but, similar to the other SE line, the 4SE sports this glossy orange coating instead of black which is more common in most Celestron telescopes. 

Overall they are very compact and not very heavy to carry around but we do recommend finding a case that matches their size or bigger to put some cushioning inside like bubble wrap or foam to keep everything safe. Both of them are coming with all basic accessories to use right out of the box and since they have this alt-azimuth mount which is more similar to a camera tripod, the installation will not take so much time. In the box you will also receive eyepiece but there is no barlow.

Celestron NexStar 130 SLT and 4SE Specification

When talking about a telescope, the first thing you may want to know is probably their aperture because this is the most important part to consider since the aperture size decides how much light goes through the lens/mirror. As the name suggests the 130 SLT is a 130mm or 5.12-inch type while the 4SE is a 102mm or 4-inch type. They also have different focal lengths at 650mm and 1325mm respectively which is why the view in the latter will be bigger in comparison.

As for the focal ratio it is f/5 and f/13 while the eyepiece that comes in the box are 25mm with 26x magnification and 9mm with 72 magnification compared to only one 25mm with 53x magnification for the maksutov-cassegrain type. They also have a finder coming with the main tube and they are the same StarPointed red dot scope. 

Celestron NexStar 130 SLT and 4SE Performance

Moving further, let’s see how Celestron NexStar 130 SLT and 4SE work and we want to mention that since 130 SLT is a Newtonian, this telescope may need collimation once in a while or before the first use so make sure to have collimator ready if you don’t have one yet. Cassegrain may need collimation as well but it is very rare. Due to the huge difference in focal length and focal ratio, you will see objects closer using the 4SE compared to the 130 SLT. 

For example the moon will look bigger as the image has a narrower field of view. This is why they are often chosen by planetary observers yet if you are often aiming at faint deep sky objects, we don’t think it will be as amazing. Looking at further sophisticated planets like Saturn are easy with these telescopes but you will still need a barlow lens and using them, the planet does seem closer with 4SE but blurrier. 

Celestron NexStar 130 SLT and 4SE Finder

The last part we want to mention is their finder scope and it seems to be an issue on the newer Celstron telescopes because there have been so many complains about the performance of their pointer which used to be fine. In some cases the pointer doesn’t work even when you already replace the battery and some people also find their pointer doesn’t work right out of the box. In addition be prepared to stock lots of AA batteries for the mounting since they will need 8 of them.

Celestron NexStar 130 SLT vs 4SE

Both of them are two great telescopes for the budget but are also different as well because we do think that the 4SE is more ideal for planetary observing as it has longer focal length and ratio so the image appear to be more pleasing but for other object like Orion Nebula, they are equally amazing. Our issue is only on their finder as they are difficult to use and take so much time as well as the battery that runs out very fast, making them less convenient.

All in all, there are no bad options between the two as they are equally amazing for the price point but in comparison we do like the NexStar 4SE as it is showing image in a narrower field hence the planets looks bigger and we love how Jupiter looks with this one.
