The 4SE also has an integrated “flip mirror” at the back, which means that there is a built-in star diagonal which can be retracted to allow light directly out of the back of the telescope and into a camera adapter, usually for a DSLR or mirrorless camera.
Celestron’s NexStar 4SE’s big selling point for this model is the GoTo computer.
You can select from a database of 40,000 night sky objects. When you’ve picked a target, the motorized mount will slew the telescope around to point at the object you’ve chosen.
Once in your eyepiece, the motor will track it as it moves across the sky so you don’t lose sight of it.
Theoretically, this is a great solution for the more casual backyard astronomer who is more interested in spending time outside seeing objects than finding them.
The 4SE’s 102mm aperture isn’t huge, but the portability of this rig far outweighs any size limitation. And Celestron’s nicely coated optics make the most of every photon fetched.
If you want to get your feet wet with astrophotography, the 4SE has a camera control option. It helps you take a series of long duration exposures with your DSLR camera.
Just don’t try to hang a very heavy camera body on this little telescope; an oddly weighted mount won’t track well enough for sharp images.
Because it is a compound telescope, you are going to get picture-perfect images and a wide field of view. Of course, the StarBright XLT coating on the Celestron 4 SE helps, as does the inclusion of a 25 millimeter Plossl eyepiece that delivers 53 times magnification, as well as a 12.5 millimeter eyepiece that can be added to give you 100 times magnification.
As a result, this one of the best grab and go computerized telescope will be powerful enough to capture impressive details of many objects in our solar system, including the Moon, Jupiter, Mars and other planets.
Deep-sky objects, however, will appear less impressive than with a bigger aperture telescope.
The 4SE is so small and light, and the tripod folds so easily, you can quickly jump into almost any vehicle and drive to find dark skies.
And someday, if you grow into a larger telescope, you’ll probably want to keep this one as a “grab-and-go” scope. It’s great for chasing solar eclipses in faraway locations where you can’t lug a lot of luggage.

Best Small Telescope Buying Guide 2021
Buying a telescope for home use is an important step towards a new level of appreciation for the night sky, and the wonders found within it.
Wondering what features you should look for in a telescope? It helps when you know precisely what to look for in a telescope before you spend a fortune buying it. Many people feel frustrated if the brand they purchased couldn’t fulfill its purpose, this can be daunting especially if you are a beginner. What telescope should you buy? You can use the following explanation as a guide to enable you to choose the right telescope.
Features To Consider When Choosing A Good Small Telescope
Types of Telescopes
There are three types of telescopes and each one has their strong and weak points. They are categorized by the abilities to gather light and the way they go about it.
Refractor scopes are better than every other type at viewing through light pollution. Also, they are ideal for planetary and lunar observations.
Reflector scopes, on the other hand, are perfect for deep-sky observation and don’t perform excellently with light pollution. These scopes require regular alignment and adjustment if used regularly.
Compound scopes utilize a mix of reflector and refractor elements. They’re great for general observation of the sky, and they perform well even in areas with light pollution.
The most important aspect of any telescope is its aperture, the diameter of its main optical component, which can be either a lens or a mirror.
The aperture of a telescope is the diameter of the light collecting region, assuming that the light collecting region has a circular geometry . For an optical instrument, the aperture is the diameter of the objective lens (refracting telescope) or the primary mirror (reflecting telescope). The larger the aperture, the more light the telescope can gather, and the fainter the limiting magnitude of the instrument. The field of view of the telescope decreases as the aperture increases, but the resolving power increases.
Another feature you should consider is the focal ratio. It is known as the speed of the optics. This characteristic depends on the focal length. You should look out for this crucial feature, usually the longer, the better. Use the following as a guide for focal ratio range.
f/3 to f/5 = fast, but lower power; best for deep space photography and observing full field f/6 – f/10 = slow, but higher power; best for narrower field viewing, photography of the moon, the planets, and binary stars
The focal length of a telescope has a direct influence on the amount of magnification. Basically, what this means is that the longer the scope’s focal length, the higher its magnification.
Do not assume that the tube length of the scope is its focal length. Complex scopes, despite having short tubes, usually deliver a sharp and clear image. This means that longer focal length is achievable through the proper combination of lenses and mirrors.
Magnification of a telescope is actually a relationship between two independent optical systems: the telescope itself and the eyepiece you are using. To determine power, divide the focal length of the telescope (in mm) by the focal length of the eyepiece (in mm).
By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope.
For example, a 20 mm eyepiece used on a 1000 mm focal-length telescope would yield a power of 50x (1000/20 = 50). While a 10mm eyepiece used on the same instrument would yield a power of 100x (1000/10 = 100). Since eyepieces are interchangeable, a telescope can be used at a variety of powers.
An eyepiece uses the light gathered and focused to magnify objects and generate images. Most models include one, or two eyepieces with one optimized for wider field views and the other for higher magnification.
The focal length of both the telescope and the eyepiece influences the level of magnification. To calculate eyepiece magnification, divide the telescope focal length by the eyepiece focal length.
Eyepieces with shorter focal length have higher magnification. That means a 10 mm is more powerful than a 25 mm. A Barlow lens is inserted into the focuser to double or triple the eyepiece magnification power.
Types Of Mounts
The mount is a very important part of the telescope. Some types of telescopes are better suited for a particular type of mount. There are 4 main types.
Alt-azimuth mounts are the simplest type of mount, and they are similar to a camera tripod. They allow you to move the telescope up and down and side to side. But it can be difficult to track the stars and make precise adjustments. For this reason they are mainly suited for smaller, low-power telescopes.
Equatorial mounts allow a telescope to track the sky as Earth rotates. They do this with motor drives but do not necessarily require a computer system to track, although some equatorial mounts are computerized for finding objects.
Most equatorial mounts are German equatorial mounts, which use counterweights to balance the telescope. This type of mount is versatile and breaks down into smaller pieces, making even large telescopes portable.
The dobsonian is a variation of the alt-az mount, designed for reflectors. Instead of using tripod legs, it uses a heavy base that is often made of wood. This is a stable design that doesn’t cost a lot and allows for more precise movements.
A fork mount is designed for shorter tube telescopes (usually the compound type). They are motorized and do not require a counterweight since the telescope is balanced at it’s center of mass. But they are often heavier than other types of mounts.
Depending on the sort of person you are, this factor may or may not be important to you. If you are intending to use your scope at a specific place and not to ever travel with it, then the weight may not really be a point of focus for you. And besides, half the delight of having a telescope is in showing it off. For that, you may decide to travel with the scope.
