StarSense Explorer DX 130AZ StarSense Explorer DX 102AZ ; Optical Design : Newtonian Reflector : Refractor : Aperture : 130mm (5.12") 102mm (4") Focal Length : 650mm (25.6") Deep-sky objects are a little less exciting. The 80mm/3-inch aperture is the smallest of the range and will limit the brightness and clarity with which you can view night sky objects. How does the StarSense Explorer 102 compare with the CELESTRON ASTRO FI 102 MM WI-FI MAKSUTOV CASSEGRAIN? The optical design is dreadful, the mount and the focuser is plastic, and the accessories that come with it are useless. You wont be able to see many details but large planets will be visible. Your smartphone's camera must be sensitive enough to image the brighter stars on a night setting. So unless you can be sure it has those or the price is absurdly low, wed recommend you pass. There are a few differences between each of the models, so lets look at each of them in turn to help decide whats right for you. STARSENSE EXPLORER APP: The app generates a list of the best objects to view based on your exact time & location. Best regards, The camera views the sky through a mirror, enabling you to view the phones screen at a convenient angle. Again, just think about where you will use and store your telescope, as these DX models make great sense if you are short on space, whereas the other models are more inexpensive but bulkier. The clutch that holds the telescope in altitude, on the test model anyway, is fierce, so to move it you need to grasp the tripod firmly with one hand and wrench the tube up or down with the other as per the instructions. ), Celestron AstroMaster 130EQ Review (A Good Beginner Device!? We may earn commissions by recommending products on this website. These are very average specs and maybe even subpar when you consider reflector telescopes tend to offer a lot more bang for the buck nevertheless, the specs should be competent for beginners. . . All the following stages are accomplished using the StarSense app that you need to unlock using a code supplied with your instrument, which will work with up to five devices. ), Neutron Star vs Nova (How Are They Different? The device comes with 2 1.25 kellner eyepieces at 25mm and 10mm, a StarPointe red dot finderscope, a 90 degree erect image starpointer, a Manual Alt-Azimuth mount, a StarSense Explorer phone dock, a tripod and a bunch of other miscellaneous documents. We previously complained about the lack of targets in the apps database, but Celestron has updated the app and drastically expanded its number of objects, greatly increasing its overall utility. This is not to be confused with smartphone attachments that simply enable you to take photos of bright objects through the eyepiece, as found on some other beginners instruments.
