The great thing about this computerised telescope is that it can be operated completely manually if you don't want to use the GoTo functionality. Its database contains 42,900 objects and it’s capable of saving up to 25 custom presets, too. It even has 10 different slew speeds (from 1x to 1000x) making it possible to whizz to your favorite celestial objects in no time. However, users will need a power supply as there is no option to insert batteries.Īlthough visually it looks like it wouldn't hold collimation for any sustained length of time, it does, so you don't need to worry about realigning the components during your observation time. The Sky-Watcher 250P can be assembled in seconds and doesn't need to be disassembled between uses like other truss tube models making it ideal for those that want to take it with them in the car to multiple locations. This makes it an excellent candidate if you're going to be using your telescope for astrophotography. The build quality is excellent and the optics are flawless, providing clear views without colour fringing as well as an excellent tracking system that doesn't drift off target. It's still quite heavy at 9.53KG but is still far lighter than the Evolution 8-inch's 16.1KG. Some people prefer this no-fuss, no bright phone screen method, and it means you're not going to lose connectivity during your session. The 6SE doesn't have built-in Wi-Fi meaning it can't be controlled by your phone, instead it is operated solely using the hand controller. The batteries do drain pretty quickly so for back garden sky sweeping we'd recommend purchasing an AC power cord and saving the AAs for when you can't access a power supply. A small step down in price and complexity, the NexStar 6SE forgoes some of the bells and whistles on the NexStar Evolution 8" to streamline functionality and save on cost, making it more accessible for those new to astronomy or astrophotography.īring some spare batteries or a long power lead with you because the 6SE is powered by 8 x AA batteries (or an AC power cord) rather than housing rechargeable lithium-ion batteries. This is a more affordable offering from Celestron (versus the NexStar Evolution 8-inch we discussed above). Additionally, it has several convenient features such as two accessory trays for storing eyepieces, integrated handles, as well as the charging port we've already mentioned. It also comes with a handset if you'd prefer to use less tech or if your smart device has run out of juice. It has its own Wi-Fi so you don't need another internet connection, either. With your location settings turned on it can pinpoint exactly where you are in no time at all and you can use the 'tap and go' interface to quickly find the desired sky object, or search through the database of over 120,000 objects. The NexStar Evolution 8" can be controlled wirelessly using your phone or tablet with the Celestron app which features SkyAlign technology. It also works as a power bank which you can use to charge up your other devices. A single charge will give you 10 hours of viewing pleasure. You don't need batteries or an external power supply for this computerised telescope, just remember to plug it in to charge before your evening of astronomy. Whether you’ve never used a telescope before or are an experienced astronomy veteran there should be something for you. With a camera attached, this enables astrophotographers to take out-of-this-world long exposures of deep space.Ĭomputerized telescopes can be crazily expensive, but here we've sought out some affordable options for beginners working with a modest budget, and also those with a little more cash to spend who are serious about astronomy. Once properly aligned it takes just a few moments to dial in your desired object and, at the touch of a button, your telescope will slew to it and, in most instances, continue to track it. Whether using an in-built hand-held control or an app, computerised telescopes often come with databases filled with tens of thousands of celestial objects for you to discover. However, increasingly they can connect to apps on a smart device for full control and functionality. They can also be aligned using dedicated computer software when hooked up to a laptop. In a bid to reduce vibrations on the instrument itself they often feature a hand-held control to avoid physical touching of the telescope. Computerized telescopes function by way of a motorised mount that controls the positioning of the telescope as it points towards the night sky.
