Which telescope gives the better first look at the sky?
These two Celestron telescopes aim at very different kinds of beginner astronomer. The AstroMaster 114EQ is the cheaper, more traditional manual reflector, while the NexStar 90SLT-Mak adds computerised GoTo convenience in a more compact Maksutov-Cassegrain design. If you’re choosing your first serious telescope in the UK, the real question is whether you want more aperture for less money, or more ease of use and portability for a higher price. That choice matters even more under British skies, where light pollution, cloudy nights, and limited observing windows reward equipment that is either simple to set up or genuinely capable when the clouds finally part.

Celestron 31042 AstroMaster 114EQ Newtonian Reflector Telescope, Dark Blue

Celestron 22087 NexStar 90SLT-Mak Portable Computerised Maksutov-Cassegrain Telescope with Quick-release Fork-arm Mount, Accessory Tray and 'Starry Night' Special Edition Software, Grey
Our Recommendation
Product A is the definitive recommendation for most buyers because it gives you a larger 114mm aperture, better light-gathering, and a much lower price of £219.00 versus £351.99. That makes it the stronger choice for the Moon, brighter deep-sky objects, and general value in UK observing conditions. Product B is more convenient, but its 90mm aperture and higher price make it harder to justify unless you specifically want GoTo simplicity and portability.
Detailed Comparison
Display
Strictly speaking, telescopes don’t have a screen in the way a laptop or phone does, so the closest equivalent is the view they deliver at the eyepiece and how easy it is to find targets. On raw light-gathering and image brightness, Product A wins. Its 114mm Newtonian reflector has a larger aperture than Product B’s 90mm Maksutov-Cassegrain, so it collects more light and will generally show brighter views of star clusters, nebulae and the Moon. That extra aperture is especially valuable in the UK, where light pollution often washes out faint detail and you want every millimetre you can get.
Product B wins on display usability in the sense that its computerised GoTo system helps you locate objects far more easily. If by “display” you mean the experience of finding and framing targets, the NexStar 90SLT-Mak is the clear winner because the mount does the pointing for you. For beginners who struggle with star-hopping, that convenience can feel transformative on a cold, damp evening.
Performance
Product A wins on sheer visual performance per pound. A 114mm reflector typically gives a noticeably more capable deep-sky experience than a 90mm Mak, especially for open clusters, brighter nebulae and lunar detail. The AstroMaster 114EQ should also be more forgiving for casual observing because the wider field of view helps you locate objects manually. However, Newtonian reflectors can require collimation, and the EQ mount has a steeper learning curve.
Product B wins on high-magnification planetary and lunar use, at least in principle. Maksutov-Cassegrains are prized for sharp, contrasty views of the Moon, Jupiter and Saturn, and the compact optical tube is excellent for travel. The catch is aperture: 90mm is respectable, but it simply cannot gather as much light as 114mm, so faint targets will be harder. In UK conditions, where transparency is often mediocre, that matters a lot. Overall performance winner: Product A for most beginners, Product B only if your priority is compact, crisp planetary viewing.
Build quality and design
Product B wins here. The NexStar 90SLT-Mak’s compact tube and quick-release fork-arm mount make it a more modern, user-friendly package. Maksutov tubes are also naturally sealed and generally low-maintenance compared with open Newtonian designs. The included accessory tray and Starry Night software add to the polished feel, and the computerised mount is designed to reduce the frustration that can sink beginner enthusiasm.
Product A is more old-school in design. The AstroMaster 114EQ is a straightforward Newtonian on an equatorial mount, which is mechanically simple and proven, but the overall experience depends more on the user’s patience and willingness to learn. The EQ mount can be awkward at first, particularly when adjusting for different targets. For build and design, Product B is the more refined and beginner-friendly system.
Battery life
Product A wins by default because it does not rely on a powered computerised mount. There’s no battery anxiety, no need to keep spare AA cells or a power pack charged, and no risk of the telescope becoming unusable halfway through a clear spell. In the UK, where you may only get a narrow window of clear sky, that simplicity is a real advantage.
Product B depends on power for its GoTo features, so battery life becomes part of the ownership experience. While this doesn’t make it unusable, it adds cost, planning and another point of failure. If you want true grab-and-go independence, Product A is easier to live with.
Price and value for money
Product A wins decisively on value. At £219.00, it is £132.99 cheaper than Product B, yet offers the larger aperture and the more capable light-gathering system. For a beginner who wants the most telescope for the money, that is a strong argument. The AstroMaster 114EQ is the better buy if your budget is tight and you want to spend the least while still getting a meaningful step up from binoculars or a tiny department-store scope.
Product B is not overpriced for what it does, but its value depends on whether you will actually use the GoTo system and appreciate the portability. At £351.99, it asks you to pay a premium for convenience rather than aperture. If that convenience prevents frustration and keeps you observing, it can still be money well spent. But on pure value, Product A wins.
Game library/features
Using your requested category in telescope terms, Product B wins on features. The NexStar 90SLT-Mak includes computerised object locating, a quick-release fork-arm mount, accessory tray and Starry Night Special Edition software. Those extras make the whole package more guided and more accessible for newcomers, especially if you want to spend less time hunting and more time observing.
Product A is much more basic. It offers the core telescope experience without the software and automation layer. That simplicity can be a feature for some people, but if you’re comparing feature count, Product B clearly has more going on.
Overall user experience
Product B wins for ease of use. If you want the telescope to help you find the sky rather than make you learn the sky first, the NexStar 90SLT-Mak is the smoother experience. It is also easier to transport, and the Mak design is attractive for urban observers who want a compact setup for short sessions between clouds.
Product A wins for the more satisfying long-term observing bargain. It gives you more aperture, lower cost and no dependency on batteries or alignment routines. Yes, the equatorial mount and reflector maintenance ask more of the user, but many beginners grow into that and end up with a better understanding of the night sky. In the UK, where clear nights are precious, the best telescope is often the one that is ready, simple and capable when the sky finally cooperates.
Overall summary: Product A is the better all-round buy for most people because it delivers stronger optical performance and far better value for money. Product B is the better choice if your top priority is convenience, compactness and computerised finding of targets. If you want the best telescope to learn the sky with and get more aperture for your pound, choose Product A. If you want the easiest path to actually observing on limited clear nights, choose Product B.

It also suits buyers who prefer spending less now and perhaps upgrading later.
Buy the Celestron 22087 NexStar if...
Buy Product B if you know you will value computerised GoTo more than aperture. It is the better choice if you want a compact telescope for quick sessions, easier target finding, and a more guided beginner experience. If you are likely to get frustrated star-hopping under light-polluted UK skies, the NexStar may keep you observing more often.
