![]() ![]() I could easily just use a stick PC instead, then use my phone to remote view it. I use a SkyFi unit on my mounts to talk to SkySafari. If it did those two things well, I would ditch SkySafari. Stellarium on a computer is really missing two very important things though: observing lists and, logging. The phone app and the web app are very paired down versions with much fewer options. You can update individual solar system bodies, use DE441, use HIPS Sky Surveys, and search SIMBAD. ![]() There are lots of differences between Stellarium based on how it's used. ![]() I can't speak to Sky Safari, or the other sites/apps, but I've had good success & viewing using stellarium. The display options are very easy to use, the layout is very user friendly, and I've found it to be very accurate. Ive been using Stellarium for a few years now and find it to be very easy to use. They just disagree on where almost everything else is in the Universe. Since I only have one data point here do you folks have similar results or is this variability typical for free online stuff? Note that Stellarium and Formilab give identical numbers for Neptune's Right Ascension and Declination. Or at least there is something with a light blue tint there and nothing even close to being Neptune close to the magnitude 7.5 star. Formilab has Neptune right next the 7.5 magnitude star while Stellarium has it a lot closer to halfway between them, Well I checked last night and indeed Neptune is around halfway between the magnitude 7.5 and 7.0 stars. In the Formilab picture the tiny pitchfork is the symbol for Neptune. Note the star labeled HD 221600 in Stellarium is the same star as the one labeled as 7.0 (for its magnitude) in Formilab. The field of view here is closer to 2 degrees. Before this I had used another called Formilab and I got a screenshot like this. ![]() As an example this is a screen shot of where to find Neptune according to Stellarium. There seems to be differences between them as to where exactly some things are. I have used a number of the free online applications to help find celestial objects. ![]()
