This is a great technology. I attached it to a Celestron 9.25"" NexStar Evolution. It works very well.However, Celestron WiFi doesn't.When I tried to set up StarSense using Celestron WiFi and the SkyPortal app on iPhone (not iPad), the StarSense alignment process would align, then lose connectivity, then need to be aligned, then lose connectivity, then freeze. I have been reading several online forums for amateur astronomy, and the Celestron WiFi combined with the SkyPortal app freezing the phone is a common problem.Some users have wireless providers that use ""smart"" WiFi apps to bounce back and forth between WiFi and Cellular Data, shutting off WiFi on disconnect, and thereby ""improving"" battery life. These apps appear to conflict with SkyPortal and Celestron WiFi. I have no such app, but I did have tethering enabled, and this probably does pretty much the same thing to SkyPortal as the smart WiFi apps. I'll give it a try again with tethering disabled, but after 5 weekends of trying to get Celestron WiFi to work with SkyPortal (I also tried with SkySafari 5 Pro, where I can save and restore all kinds of settings, but SkySafari 5 Pro is just as bad as SkyPortal with respect to losing connectivity and freezing) I am pretty fed up with SkyPortal. None of this compatibility information is available from the Sky Safari folks, who are contracted by Celestron, nor is it available from Celestron. You have to go out and dig it up yourself. Celestron should have a better knowledge base, along with better unit testing and quality assurance. I know they aren't software developers, and they don't charge for SkyPortal, but I also can't charge them for all of the time I spent trying to get SkyPortal to work with StarSense. Take a lesson from Apple: to sell your hardware, you need easy-to-use software that actually works.I have found the StarSense hand controller much easier to use than SkyPortal. StarSense will do alignment provided it can find enough stars. I have never tried to align on solar system objects, and I don't even know if that is possible with StarSense. You will still need to calibrate StarSense after you've aligned it, which essentially tells StarSense how misaligned the camera is with respect to the telescope aperture. In theory, you should be able to remove the camera from the telescope and replace it without recalibration. I have never been able to affix the camera to the telescope so that recalibration can be skipped. It only takes a few seconds, but afterward, you have to align again. With the hand set, this is about a 5 minute process: align, calibrate, align. With the SkyPortal app, you may never complete this process.If StarSense can't find enough stars, use the NexStar controller together with geolocation information, sky maps, and a star finder. I know you can solar system align NexStar, because I do that in my front and back yard several nights a month using the moon or a planet, and I can even align on the sun when I have a white light solar filter attached. StarSense just gets lost in my light polluted neighborhood, with a very busy airport located 6 miles to the south putting all kinds of lights in the evening sky.I'm not sure I would recommend this item for beginning astronomers. For one thing, it costs about as much as a kid's (really nice) starter scope. For another, learning how to read and use a sky chart - and compass - is not a bad thing. It's also a good thing to know how to align your telescope to a finder scope, and how to use the finder scope to point at objects in the sky. Since StarSense gets the information it needs directly from the telescope hardware, you also don't need to know what kind of mount you have, which means that you don't know all that you can do with your telescope. Lastly, if something doesn't go right in the connection, alignment, and calibration of StarSense, you should be able to swear very loudly, remove the StarSense camera and controller, attach the NexStar controller, cycle power on the scope, and then align it yourself.
