Designed with the beginner in mind, the ExploraScope 114AZ is the perfect telescope to discover the Moon, rings of Saturn, moons of Jupiter, Orion Nebula, and all the best celestial objects. The included red dot finderscope helps you sight objects in the sky and center them in your telescope’s eyepiece. Use the new altitude slow motion rod for precise pointing and following objects as they appear to move across the sky. ExploraScope comes complete with everything you need to get started with amateur astronomy: 2 eyepieces, a 3x Barlow lens to triple the magnifying power of each eyepiece, an erect image diagonal for correct image orientation, and a full-height aluminum tripod. Plus, you can download Celestron’s SkyPortal app for iOS and Android devices to help locate and learn about celestial objects. With ExploraScope, you get the best out-of-the-box experience in the entry-level price range.

The scope came with the cap for the secondary mirror (which had adhesive to keep it in place) stuck to the primary mirror. When I pulled it off it left a smudge of adhesive on the mirror. I had also bought a laser collimator with the scope only to find that this is a Bird Jones style scope requiring partial disassembly to use a laser collimator. Also, the primary mirror is not center dotted. This all seemed like more potential work that I really wanted to take on as a novice.
I called Celestron to ask if the primary mirror smudge was an issue, they said it was not. I also asked why the primary mirror is not center dotted for collimation and they said the scope was collimated at the factory and would not need collimation by the consumer. The Celestron rep was helpful and patient with my questions, so no problem there.
I was under-whelmed with my first two viewings. The only easy target at the time was Jupiter. It was rather fuzzy and undefined. And so I undertook to disassemble the scope to center dot the primary mirror and laser collimate it. It definitely needed collimation. The secondary mirror was way off. And of course the primary mirror was off too as expected after I disassembled it. To my relief, all of this was pretty easy to do. I had the whole project done in about 30 minutes.
And that did the trick. Jupiter resolved nice and sharp. I could see the cloud bands and the four moons were sparkling jewels. Better yet, Saturn was now up. What an awesome sight! Beyond my expectations. I could see the rings clearly to the degree that I could tell how they oriented around the plant (with a 12.5mm eyepiece and a 2x Barlow). I couldn’t make out the Cassini Division, but I was very impressed with the detail and clarity provided by this beginner’s scope.
So now, for the money, I’m very pleased with this scope. But those contemplating purchase should know that this is a Bird Jones style scope and it may need collimation to get the most out of it.
One last note: the eyepieces supplied are not very impressive, but useable. I bought a set of Plossl eyepieces (20mm, 12.5mm, 6mm) and a 2x Barlow under the assumption they will still be of good use if I upgrade to a better telescope in the future. I think that was a good supporting purchase.

After being frustrated for quite a while of only making things worse while adjusting, I finally find that it's not actually a Newtonian reflector, it's a Bird-Jones style reflector/refractor hybrid with a 2x barlow lens built in the focuser tube. That explains the chromatic fringing, I expect. This makes all collimation techniques and tools for Newtonians basically not applicable, and none of the forums about telescopes have anything good to say about either the Bird-Jones design, or good reports of how to collimate except to disassembly the optics every time.
Combine the lack of information in the package about the scope itself, and this one is probably going to be frustrating for beginners, and not something that will be able to be maintained and adjusted for a good long term experience.
The out-of-box alignment wasn't that bad, I think, and the original image quality was OK, so for a basic point-and-shoot, it's alright, I suppose. But if you're actually wanting to get into telescopes and be able to fix/align properly, find something else.
Wish I'd known what I know now before buying. I'd for sure choose a different one.

1. Good stable mount - I preferred to use AZ mount as it is easier to use. It has slow motion adjuster which is some time difficult to operate but it is useful to track object when using high magnification. Mount is light weight and very easy to carry. Assembly of scope with mount is just two step and can be done within a minute.
2. Overall very compact size - I wanted a telescope which could give magnification in 150 - 250x range so I went for this telescope. Its focal length is 1000mm and primary mirror is 114mm, telescope tube itself is short around 600mm. This is not a true Newtonian reflector but a Bird Jones version, which has spherical corrector lens in focus tube to correct for spherical abbreviation and increase focal length. Overall weight of the telescope is 3-4Kg and its very easy to move and carry this with you.
3. Performance - Since it is a bird jones design it has some slight disadvantage over true Newtonian reflector telescope like overall FOV would be less then same aperture size Newtonian scope. Corrector lens would slightly reduce the brightness. But higher magnification and compact size overcome these disadvantages. My experience is below 150x magnification image quality is good and it is easier to focus the image but should have good quality eyepiece. Above 150X magnification resolution of focus knob is not sufficient to accurately focus the image, you have to give several trials to fine focus the image. From my experience till around 210-220x magnification only you get fine sharp image. Cluster and nebula views are good with this scope. I have seen just seen Venus and Jupiter planets as of now. For Venus you need good eyepiece and filter to get good image. Jupiter viewing is good, you can clearly see its four moon and depend on viewing condition you can see some more detail of Jupiter. View is best with plossl eyepiece and magnification of 150-200x.
Things which I do not like of the product are the eyepieces supplied with it. First one is 20mm erecting eyepiece, it is good for terrestrial viewing but due to its very small fov it is useless for finding objects in sky. At low or medium magnification, it will be good to have at least one eyepiece that is having good fov. It will be helpful in quickly locating and studying the objects in sky. I have celestron 15mm Kellner eyepiece from the Astromaster eyepiece set. With this you get good fov but image is focused around centre, you will see blurred star images at the edges but it is still sufficient to locate the object. From the same astromaster kit I have 6mm plossl eyepiece that gives nice and detail image at 166X zoom. Second 4mm Kellner eyepiece that comes this telescope is also not useful most of the time as I have 6mm plossl that gives me better image then 4mm. With 4mm you get 250X magnification and with this you can watch some good detail of moon surface. Planets and deep sky object view are not sharp with this. This telescope also provides 3x barlow which can be used only with 20mm eyepiece. Some time I use this barlow with my 15mm eyepiece that give me 200X zoom.
This telescope is good if you like manual AZ mount and need compact and light weight product. Focusing at high magnification is challenge and you need to purchase some good quality eyepieces to experience true potential of this scope. My suggestion is buying plossl eyepiece for high magnification and some good quality 15 -25mm wide FOV eyepiece. If you need to do collimation then buy laser collimator as it is easiest and accurate method. But make sure you remove corrector lens from focus tube before doing collimation.
You will also receive starry night simulation software. It is good tool to study star positions and useful in finding some great deep sky objects.
