About this product
The Celestron StarSense Explorer LT80 AZ refractor telescope uses your smartphone to navigate the night sky. It features the patented StarSense dock that holds your phone securely while the free StarSense Explorer app analyses the sky and calculates your position in real time.

The 80mm aperture and altazimuth mount provide stable views of the moon, planets like Jupiter and Saturn, and bright star clusters, while 36x magnification delivers clear, detailed views.

Not worth the money.
Bought this with our granddaughter in mind as she was learning about the planets in school. It was also an ideal time for the planetary alignment. Unfortunately despite being in a dark sky area in Northumberland and setting it up correctly it was quite rubbish, it wouldn’t focus at all. We intended to send it back as it was not what we expected having read the details before purchasing, but i became ill soon after and I was eventually admitted to hospital and it was down the list of priorities, so unfortunately we are now stuck with an expensive useless item that we can’t send back and I certainly wouldn’t try to sell to anyone ! We’ve had much cheaper telescopes that have been brilliant, that made viewing Saturn’s rings very clear and awesome, but nothing could be focused upon with this, even the moon. We are reasonably competent people so I don’t think this is user error, it’s just a very disappointing buy.

Hello Sally,
From the information we have available, I can advise Upgrading the aperture lens of the Celestron StarSense 22451 Refractor Telescope from 80mm to 100mm is not feasible. The aperture of a telescope is a fixed physical characteristic, and changing it would require replacing the entire optical tube assembly, which is essentially getting a new telescope.
If you're looking for a telescope with a larger aperture, like the Celestron StarSense Explorer DX 102AZ, which has a 102mm aperture. This model offers better light-gathering capability and improved views compared to an 80mm telescope.

Hello Katie,
From the information we have available, regarding the following Celestron StarSense 22451 Refractor Telescope weighs 4.17kg and does not say that it cannot be moved or transport once it has been built and setup.
Thank you for using Q&A.
This would be suitable for viewing the moon. Jupiter can be seen with the naked eye but it will appear very small with this telescope as it only has an 80mm lens aperture. The aperture determines how much detail can be seen and the focal length determines how much magnification can be achieved with a particular eyepiece.
Hello there,
The Celestron StarSense 22451 Refractor Telescope has optimum magnification 36x and a maximum magnification 90x.
It is designed to view celestial objects including stars and planets.
Thank you for using Q&A.
Hello Ian,
The Celestron StarSense 22451 Refractor Telescope uses your smart phone and the StarSense app:
The StarSense app is used to in conjunction with the phone holder and mirror to examine the sky to see where the telescope is facing. If you want to take pictures, you will need to connect a camera to the eyepiece using the necessary adaptor.

You will probably be able to view Jupiter and possibly Saturn but they will appear very small due to the small aperture and relatively short focal length. It will probably give acceptable views of the moon though.
