Best Telescope Digital Eyepiece Cameras - Reviews

1. Celestron 93711 NexImage

Specifications
  • 5 MP color sensor
  • Live video; view & capture
  • Imaging software
  • Aluminum 1.25″ adapter barrel
  • IR-cut optical window
  • Limited 2-Year Warranty

The Celestron NexImage 5 is a versatile entry-level planetary camera, capable of taking high-resolution color video of the Moon and planets.

This video is then split into separate frames and the sharpest are stacked together for the final image.

Apart from a computer and a driven telescope, the camera has everything you need to capture beautiful images of the Solar System for the first time.

The included software automatically filters out video frames that have been the most affected by poor atmospheric seeing and retains only the sharpest, clearest frames to be stacked and aligned into one high-quality image. 

It has a machined aluminum 1.25″ adapter barrel that accepts standard 1.25″ eyepiece filters. 

The camera body has integrated C-threads affording a direct threaded connection to the telescope. 

The optical window has been IR-cut for greater precision and there is a selectable “region of interest” for sub-framing.

There is a USB 2.0 Mini-A data port on the rear of the camera that provides fast data transfer, ideal for using high frame rates to capture moments of sharp seeing.

This Celestron PowerTank is an 86.4 Wh (watt-hour) lithium Phosphate battery that is specifically designed to power your computerized GoTo telescopes for up to 10 hours of use.

The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries.

The LiFePO4 has an un-recharged shelf life of 10 years compared to 3 years for the Lithium-Ion and 6-9 months for a Sealed Lead-Acid battery.

The battery performance of the PowerTank Lithium degrades at a much slower pace than other chemistries.

This USB port can also support any accessories that require 5V USB power.

The PowerTank comes with a 6.5-foot telescope power cord and an AC charger.

It also has a built-in circuit breaker that protects all your equipment and devices from damage.

The bulkiness of this Celestron Power Tank is one of its key drawbacks. It has more significant proportions than some other power supply options.

Not only useful for setting up and powering your scope, but this telescope power supply can also be useful as an emergency roadside accessory as it includes an emergency light, and booster terminals in place to start weak car batteries. 

An included DC adapter is located in the rear back panel of the PowerTank.

Battery Packs For Telescope: Buyers Guide

Whether you’re using a telescope from home or out in nature, you want to ensure your motorized equipment will work without a hitch for the entire session. Here are a few features that you should look for in your best telescope battery packs & portable power supply.

Features To Look For In A Portable Telescope Power Tank

1. Battery Capacity

The more battery capacity a power tank has, the longer you can extend your stargazing session out in nature. But remember that more powerful power tanks typically tend to cost more. So, you’ll have to decide how much you want to spend on a portable power supply for your telescope depending on how long your typical viewing session lasts.

2. Charging Time 

The faster you can charge your power tank sooner you can take your telescope out in the open for your viewing session.

3. Dual “Red And White” Flashlights

Being a flashlight is not a primary function of a telescope’s battery tank, but it’s useful to have when you’re in the dark, and you want to quickly make some precise adjustments to the position of your telescope or some of the settings on your camera.

This is why it’s important that the red light feature is included, since it will allow you to preserve your night vision, meaning that it will be a much less jarring change for your eyes to adjust to the dark once again after you turn off the light than it would be with a more traditional white light. 

4. Number Of Power Ports

The more power ports your power tank has, the more devices you can charge and operate simultaneously.

The power tanks generally come with 12V tip positive connectors and USB ports. All of them are used for charging different types of devices. 

Some also have a 16V power port, which is only used for charging the PowerTank with the supplied charger. 

These ports are also used to be plugged in your car’s cigarette lighter output and charge the PowerTank itself.

5. Resistance And Durability

Another factor that you should look into is the build quality and durability of your power tank. Branded, good quality portable telescope battery packs like the Celestron PowerTanks reviewed in this article will be able to resist dust and water, as well as survive any accidental drops thanks to its tough and tightly assembled outer shell. 

6. Portability 

Also, make sure that the battery pack that you select for your telescope should be lightweight and portable. The PowerTank should easily fit in any backpack or carrying case, so you’ll be able to have it with you wherever you go. It also shouldn’t be too heavy for your tripod if you decide to attach it to one of its legs.

7. Ease Of Use 

Your choice of portable power supply for your telescope should also be easy and simple to use. 

There should be a minimum number of buttons on the device to avoid confusion. Make sure that the power tank also has some way to let you know how much juice is left in the tank, maybe with the help of status LEDs.

8. Compatible Devices

The telescope battery pack should have many different ports with universal nature so that they can be compatible with most USB rechargeable electronic devices and telescopes with standard power ports. 

To connect the battery to your telescope, there should be a 12V DC power port, which most computerized telescopes on the market have. 

The included USB ports will allow you to charge additional lighting sources like flashlights and lanterns, smartphones and tablets, a GPS unit, or even your camera if it supports USB charging. 

Conclusion

Depending on your needs, there are plenty of power supplies to choose from on the market.

I have reviewed the five best portable power tanks that cover a wide range of features for many different types of telescopes.

Whether you’re stargazing from home or going out in nature for a deeper look into space, you want to ensure your power requirements are met without fault.
