What is Celestron Nexstar 4SE? Is it a must-have product for GoTo? So, you are planning to buy a Nexstar 4SE? However, you are a bit confused about the features and effectiveness.
In this article, we will address all your concerns. Also, we will focus on the pros and cons to enable you to make a smart decision.
Nexstar 4SE is a small and customized telescope. This telescope is not highly appreciated by users for the size. Even if it shares the heritage of the Celestron’s C90, you will find a lot of flaws in the end product.
4SE features a small secondary mirror. However, it has long focal lengths and great optics. Both these features make this small telescope good for planetary, lunar, and even for the double star viewing. Also, it comes with the anti-orientation feature.
This feature makes it capable to view the right side image in the place of the inverted view. This is a basic feature on Cassegrain telescopes and you will not find any exception with Celestron Nexstar 4SE.
What Are the Key Features?
4SE will feature a single 25 mm 1.25ʺ Plossl eyepiece. This is considered good for low power. However, users might prefer 32mm Plossl especially when they are interested in widest views. 4SE is small and will restrict many of your activities.
The long focal point of this telescope is 102 mm. This focal length makes it a good planetary telescope. But the users will have limited options for the brightest deep-sky objects.
The catalog will be containing 40,000 objects. That means you can see above hundreds of deep-sky objects even in darker conditions. All the credit goes to the small aperture of the 4SE. There are some downsides as well.
The catalog will not have asteroids. Also, the Sky Tour Function will list some objects that might not be so convenient for views. The telescope might find it too dim for viewing.
You might be thinking that why you need such a large catalog when the viewing options will be limited. 4SE large catalog can be used for the massive stellar database and that can help to find steroids.
Does It Offer Mount Stability?
When it comes to mounting stability, it is fairly stable. The tube of the 4SE does not come with a Vixen dovetail. The benefit is that it can be used on other mounts. But the problem is with the orientation. You might experience an odd orientation.
What About the Hand Controller
There are small buttons on the hand controller. The small size might not be preferred by many. If you are wearing gloves, you might find a bit complex to use those buttons. Also, you will have to enter the date and time whenever you set your scope up.
This feature is going to consume a lot of battery. The battery life is also not that satisfactory. You might need a backup to support your activities.
Do You Need External Power Supply?
You will need an external power supply while using 4SE. So, make sure that you have extra AA batteries for the backup. As it uses eight batteries, get the right number to avoid inconvenience. Whenever the power supply will be stopped even for less than a second, your telescope will reboot.
At that time, you will have to enter the time and date again. During this process, it will eat all the batteries. So, prepare yourself for this and always pack extra batteries.
How to Deal With A Changing Location
The process might be a bit complex. Your Celestron Nexstar 4SE should be bundled with Celestron’s SkySync GPS module. It is important to update the date, time, and location. For this bundle, you will have to spend more than a hundred dollars.
Users can try the SkyPortal WiFi for the same. This app can enable them to solve this issue. They can also use this app to control the telescope by their smartphone. Here again, they will have to spend a decent amount.
