There are actually 4 telescopes in the SE series by Celestron. All of them are computerized telescopes; the 6SE can be considered mid-range, while 8SE is the most advanced in the series.

Both have literally the same features, share the same technologies, and they use the same type of power source. Some of the best features are SkyAlign, user-friendly handheld control, sky tour, and a large database of 40,000 observable objects.

They also have advanced optical coating technology, allowing the telescope to capture as much light as possible.

SkyAlign

It is basically an automatic system that allows users to easily locate every observable object listed in the telescope’s database. It does require users to input date, time, location, and point the telescope at 3 bright objects, but everything is done by using the handheld control.

The telescope basically operates based on any command sent from the remote. You can even choose any observable object in the database with the remote control.

StarBright XLT Coating

The most basic function of a telescope is to capture as much light as possible and deliver images to the eyepiece. Both 6SE and 8SE telescopes are equipped with Schmidt-Cassegrain optical design, which has better focusing capability and wide field of view compared to Maksutov-Cassegrain variant.

They also have StarBright XLT Coating which dramatically improves performance and mirror reflectivity compared to the standard StarBright. The overall lights transmitted reaches more than 83.5%. In fact, the StarBright XLT is one of the finest coatings available today for telescopes.

Portability

The most expected feature from a scaled-down version of real telescope is portability. The Celestron NexStar 6SE and 8SE are not actually very small, they are tall when assembled, but it is good to know that the included tripod and the fork arm are detachable yet easily reassembled for easier storage.

Either 6SE or 8SE is powered by 8 AA batteries or a Celestron’s 12V power supply. The batteries and power supply are not included in the package.

Bundled Software

Planetarium software called The Sky is included in the package. It is mainly a program to explore the Universe from PC. Every purchase also includes NexRemote which allows you to control your telescope from computer.

Every Celestron NexStar SE series telescope is protected by 2-years manufacturer’s warranty.

Celestron NexStar 6SE vs. 8SE

There are only few differences between 6SE and 8SE such as the lens size and weight. The difference in lens size, however, means that the bigger 8SE has better imaging capabilities.

NexStar 8SE has 203.2mm aperture and 2032 focal length, while 6SE only has 150mm aperture and 1500mm focal length. The highest useful magnification in 8SE reaches up to 480x, but 6SE does its best at 354x magnifications.

Lens size differences also make 8SE heavier at 33 lbs (including the tripod), while 6SE only weighs 30lbs (including the tripod). Although each of them has more than 40,000 observable objects, the 8SE provides slightly better options with the addition of 400 user-defined objects.

Moreover, this most advanced telescope in the SE series has more than 200 objects in the list with more complete information.

A telescope has always been a great invention allowing you to observe the universe by taking a closer look at numerous extraterrestrial objects out there.

The Celestron NexStar 4SE and 5SE telescopes make it even easier that you can now use portable, lightweight, computerized tools to do all your stargazing activities from anywhere.

Both 4SE and 5SE are small-sized telescopes powered by AA batteries; each also comes with planetarium software to help you to explore universe from your PC. They have plenty of similarities indeed, but there are also some differences as briefly outlined in the following passages.

Main Features

The NexStar 4SE and 5SE by Celestron are the same mainly in terms of technology. Both of them use the same computerized object-finding system called SkyAlign. It is in fact the feature that makes both telescopes easy to use.

You can align the telescope by using the handheld control to input date, time, and location. You also have to point the telescope to any 3 bright stars/planet, or simply to the moon.

The SkyAlign is not completely automatic, but it should not be too difficult for everyone to understand how the system works. Another good thing is that both are equipped with digital SLR connectivity, allowing you to take series of exposures remotely with your camera.

The good thing is that you can choose any particular object to observe simply by using the handheld control as well. Each of those telescopes has a considerably large database consisting of nearly 40,000 accessible objects to look at.

As you choose any object, the telescope will automatically find it for you. In some aspects, you can almost say that 4SE and 5SE telescopes are like point-and-shoot digital cameras where users only play small part in the entire photography actions.

Each telescope comes with a sturdy tripod and a single fork arm design. Tripod and fork arm break down to separate units for easier storage and better portability aspect.

Celestron 4SE vs. 5SE

They are similar in terms of control and alignment system, but they are different mainly in terms of optical design, magnification, and weight. The 4SE variant is the smallest in Celestron SE series weighing at only 11 lbs or 21 lbs including the tripod.

It uses Maksutov-Cassegrain optical design and has an aperture of 102mm. The focal length in 4SE is 1325mm to reach up to 53x magnification.

The 5SE series is simply the slightly upgraded version of the smaller 4SE. Instead of using Maksutov-Cassegrain, the 5SE has Schmidt-Cassegrain optical lens design.

Both lens designs are actually similar also, but the Maksutov provides a slightly higher resolution especially for planetary observation. The Schmidt, however, has better focusing ability for wider field of view.

The Celestron 5SE provides larger apertures at 125mm so it catches lights better than its smaller counterpart, but the focal length is shorter at 1250mm. With larger aperture, the telescope becomes heavier as well. It weighs 17.7 lbs or 28 lbs including the tripod.

Other Features

Either 4SE or 5SE is powered by 8 AA batteries which are not included in the package. It is actually possible to use Celestron’s portable 12V power supply, but you have to purchase it separately as well. Another good thing is that each of the telescopes is covered by 2-year manufacturer’s warranty.

Third Party User Reviews

Personally I do not own these Celestron telescopes, so I do not have the hands-on experience about the product. Due to that and for better understanding of these telescopes, I listed here an owner reviews of the products that I found while searching the net.

  • You may like this user review of Celestron NexStar 4SE by astro-baby.com. Quite a comprehensive hands-on experience on 4SE.
