Celestial is a complete package for celestial navigation on your iPad, iPhone or iPod Touch. It can perform celestial sight reductions, calculate fixes, present them visually, manage sights on multiple trips and assist in sight ...
Is anyone writing these 5 star reviews even using this app I have purchased almost all of the celestial navigation apps on the app store except StarPilot too expensive especially in light of its bad reviews and Celestial is the LEAST feature rich of them all First off everything is done based on UTC time Whenever you make another sight you have to do the conversion from the current time in your head before you enter it It does have the function to automatically produce the current UTC which helps when entering an actual sight since you can get the current UTC and update to the minutes and seconds of your sight Way more difficult when entering data for previous data Also the rise and set times are only displayed in UTC and you have to do the conversion in your head The rise and set times were a few minutes off from the times you may find on the internet but that is probably not a big deal More of a big deal is the accuracy of the sight reductions I entered 2 sights of the Sun that I had previously made and reduced by hand Since I had done this at my home and determined the correct fix to my location I know my results are correct The Ha and Ho values produced by Celestial matched my hand calculations but the Hc was way off I assume this difference was due to Celestial not calculating from an assumed position which must be done when your are doing a reduction via table lookup so I can t compare it directly to my results The plot of the sights looked similar to mine but there is not enough detail on the plot to estimate the fix from The fix it calculated for me was off by more than 20nm There are no details of how this was calculated so not idea of why When entering a new sight you start with no data and have to enter everything again When doing multiple Sun sights as most of us do this is extra unnecessary work when the only thing that needs to change is the sextant altitude and time In my case it led to an error since the limb defaults to none and I forgot to change it on the second sight I entered It took time to go back and figure out my error One of the major things Celestial is missing is the ability to make a running fix Are we suppose to stop the boat and take down the sails every time we want to make a fix Another major omission is the ability to compute an expected altitude that can be used to set your sextant to before making a sight Not a big deal for the Sun and Moon but a very big deal when you are trying to find a specific star or planet among all the others in the sky Celestial provides an Almanac function that produces the hourly values of GHA and Dec for the objects that match the Nautical Almanac values pretty well They give you confidence that the internal calculations are correct but you can t do much else with them You could potentially use them along with the tables from an old almanac but since no v or d values are given that correction could not be applied when using this method making this useless Overall functionality is very minimal and in my trial the fix was simply wrong Everything is just displayed black and white which kills you night vision when trying to use it for twilight sights The iPad version is just a scaled up iPhone version with the help information always displayed Some of the other apps that are available give you a lot more for your money and produce the correct results         Disappointed Single Handed
This app is an excellent value I have been practicing celestial navigation for over 20 years and have programed calculators to provide almanac data and reduce sights This app does everything you need The Sky View feature is very nice and greatly facilitates sight planning Touching the screen in the Sky View mode provides accurate HC and azimuth values for each body The plotting function however needs improvement the LOPs are on a small screen with a fixed scale spanning 120 NM You can t see the area of intersection well enough to estimate the precision of the fix or identify which sights might be outliers and better deleted Some kind of pinch to expand feature would be a big improvement and warrant five stars for the improved app The app does not have some of the nice bells and whistles like sight averaging star ID from observed altitude and azimuth or great circle sailing If you want all that and more you should buy StarPilot but it is more than twice the price This app will serve your needs provide plenty of practice and lots of fun and along with a sextant enable a safe return from the longest voyage in the event space aliens zap all the GPS satellites Actually in that case you would need a chronometer too                 Excellent App Ol' Navigator
Very usefull apps fast and easy to use It helps saving time for calculations especially to officers like me working on tankers doing celestial navigation in long voyages There s one more lacking in this program must have a compass correctors or determining compass error Hoping to have this updates guys to make this apps complete I recommend this to a friend                 BridgeMan Kimboo's
I have been practicing celestial navigation since 1968 and have recently looking for a good application for my iPhone and iPad even old horses sometimes learn new tricks Celestial by Navimatics is well thought out and a snap to use after just a little practice I look forward to using it on my next passage I ve run a bunch of star sights and sun line through the program and they all check out There are a few tweaks and additions that will make the application even better and their customer service is absolutely the best I have encountered I will be looking into other programs by Navimatics                     Great App GunsmokeOffshore
Pretty much basic Should make controls more user friendly and add GPS input for time LAT LONG as an option Lacks sight planner and basic navigational mathematics like rhumb line and great circle sailing No option for imperial metric input             Basic Srđana
I m a professional mariner and have been looking for an app for celestial navigation for a long time This seems likes good start I hope some updates will include sailings and compass correction Although a little pricey it s nothing compared to the 80 app I gladly took a chance downloading this app and so far looks good I m a big fan of celestial navigation and I hope for generations to come this art will be passed on Now that my cadet days are over and I m in the world of coastwise tankers I try to do celestial whenever possible to keep my skills toned I can t wait to try out the app and compare to my long handed calcs                 Finally cmenezes116
First my comments are based as a Prof Mariner w 18 years of ocean sailing Academy grad and current Cel Nav Teacher Out of the box this app is easy to use pages are laid out great Data entry is easy to enter Use the help section first and you have no problems even though I went staight into it it corrected the few wrong entries I made on purpose such as Lat Long number configurations Use the app in class to check USCG problems Some differances found with resulting intercept distances but explainable and sensible based on assumed DR Lat or DR Lat with course and speed Initially had low memory problem on iP4 but Navimatics Tech support staff returned email off of their web site in less than 24 hours answered question and apologized what more can you ask for I did not use TRIP page function so can not comment on this page Txt can be a bit small on iP4 but hey screen is small bet this app is awesome on iPad I have a few more suggestions to send them to make the app more informative such as the ability to add Zone Discription and have Zone Time displayed in Sight and Almanac pages but trival issues Only major addition I would like to see our SAILINGS but only practical field use ones Parrellel Mercator and Great Circle Dist Initial Course and Lat Long Vertex points along GC route I highly recommend this app A bit pricey yes but I feel worth it compared to a Nav Calculator or cost per hour doing cel nav reductions long hand in the field                     Field ready and practical to use QCKBRIT
