![]() As you get close the app zooms-in and you get a bullseye to manually slew to. Luckily that’s very easy to do and the control you get is surprisingly precise. Yes, you have to manually move the telescope. Directional arrows appear on the app and guide you in the general vicinity of your target. First you choose from a list of objects on the StarSense app (split into both ‘City Viewable’ or ‘Dark Sky Viewable’, with lots more faint targets added especially for the advanced optics of the Celestron StarSense Explorer 8-inch Dobsonian). Once that’s done it’s so, so easy to use. It’s not difficult, but beginners may initially struggle with the first step. Then you need to get it in the centre of the eyepiece’s field of view. ![]() All you need is a clear sky in a deep twilight, an obvious bright star – any one will do – and the confidence to use the red dot finder to achieve a rough alignment. This is merely to allow the software to know that what it sees in the centre of the mirror behind the smartphone is aligned with what’s in the centre of the eyepiece. The first is that while this is as automatic a process as possible, the user does still have to align this telescope with a bright star. Bypassing the hand controllers in use by ‘Go To’ telescopes, StarSense lives on your smartphone and your smartphone lives on the telescope.Īlthough I had no problems while using the Celestron StarSense Explorer 8-inch Dobsonian there are few things to think about that aren’t obvious from the get-go. Setting-up and alignment is all about Celestron’s magnificent StarSense app. Our advice is to put a 5,000 mAh portable battery in this telescope’s base and trail a long 2m cable to the smartphone holder, whose universal smartphone clamp does have a cut-out for exactly that. With a 10-inch aperture, the Classic 250P Dobsonian is 1235 times brighter than the human eye This simple yet effective design is perfect for visual. Use a smartphone for a few hours’ star-hopping and you’ll soon be searching for a portable battery. That does, of course, raise a minor issue about battery power. The StarSense app also includes spoken word audio commentaries for most of the objects, so it’s worth pairing some wireless earphones with your smartphone while observing. Both attach to the top of the telescope close to the eyepiece. It’s excellent quality and offers up to 48x magnification.Īlso in the box is a red dot finder to help you point the telescope at targets without the app (or during the day, or for quick-and-dirty targeting at a planet or the Moon) as well as a smartphone holder. The Orion SkyQuest XT10i IntelliScope Dobsonian Reflector telescope entertains amateur astronomers worldwide by virtue of its dazzling optics, contemporary design, and most exciting of all, the ability to locate any of more than 14,000 fascinating celestial objects with pushbutton ease Our big, 10' diameter IntelliScope Dobsonian features an. Once they’re fastened together the entire unit isn’t super-easy to move, but it is very easy to manipulate for pointing at celestial targets.Īs well as a code for using StarSense app and a free download of Celestron’s Starry Night Basic Edition Software the box includes a 0.98-inch/25 mm Celestron Omni Plossl eyepiece. Both weigh about 10kg and have carry handles to make them easy to move separately. We recommend buying the accessory shroud, which will improve contrast at the eyepiece and offer dew protection for the primary mirror.(Image credit: Jamie Carter/Digital Camera World)Ī Newtonian reflector Dobsonian telescope with an 8-inch aperture and a smartphone mount attached to its side, the Celestron StarSense Explorer 8-inch Dobsonian comes in two parts – telescope tube and base. ![]() * Single-speed focuser rather than a 2-speed focuser (upgrade requires a new focuser not just a 10:1 reduction knob) * White aluminum-tube secondary rather than a cage assembly ![]() The significant differences between this telescope and the Explore Scientific Generation II model are: Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience. Details on planets and deep-sky objects will be visible even for inexperienced observers. A 254mm mirror collects hundreds of times as much light as the naked eye. 899.99 3 easy payments of 300. ![]() This is an ideal workhorse for the deep-sky observers. The combination of high altitude bearings with optimized aluminum structures allows fine-adjustment flow at high magnifications. The entire structure has been optimized for maximum stiffness with minimal weight. Disassembly of the scope, which does not require tools, ensures a trouble-free transport of this great scope - even in small cars. Nowhere do you get as much light for your money like a good Dobsonian. This is a hybrid truss-tube Dobsonian because the secondary-mirror is held inside a tube (like a traditional Dobsonian telescope) rather than an open cage. ![]()
