The text will turn blue during calculation and then back again once complete. The text will turn blue during calculation and then back again once complete.
When you first install it, all positions will be estimated from UK as the default location and all the text will be white; from the moment you get your first GPS lock with the clock, it will save your location, recalculate accordingly and change the text to red, ideal for maintaining night vision, the calculations will also now be relevant to your location and time. If you have not used the GPS yet, I suggest using it outside briefly to get your first fix as the initial one can take a bit longer, although it should still just be a minute or 2 max normally.

Lat and Lon are saved in a file called **astral.config**. You can review this file if you want to confirm current coordinates or even hard set different values \- although be careful doing the latter as there’s no error handling to manage bad values here so you'd have to delete the file and have the app generate a new one if that happens, also the GPS functionality will overwrite anything you put in here once it picks up your location.

There can currently be a slight error mainly to the Az at times due to a firmware issue for acos (arccosine) that affect spherical calculations but I have used an estimator function that gives a good enough accuracy for general observation so shouldn't noticeably be too far off. I'll be implementing acos for better accuracy when the fix is in a standard release and the update will still include the current estimate function to support a level of backward compatibility.

The moon phases are split into the 8 phases with an image for each - new moon would show no image. The moon phases are split into the 8 phases with an image for each - new moon would show no image.
The compass is displayed above the minute digits, if you get strange values or dashes the compass needs calibration but you just need to move the watch around a bit for this each time - ideally 360 degrees around itself, which involves taking the watch off. If you don't want to do that you can also just wave your hand around for a few seconds like you're at a rave or doing Wing Chun Kuen.

Also the compass isn’t tilt compensated so try and keep the face parallel when taking a reading. Also the compass isn\’t tilt compensated so try and keep the face parallel when taking a reading.

Put together, initially at least, by "Ben Jabituya", https://jabituyaben.wixsite.com/majorinput, jabituyaben@gmail.com. Feel free to get in touch for any feature request. Also I'm not precious at all - if you know of efficiencies or improvements you could make, just put the changes in. One thing that would probably be ideal is to change some of the functions to inline C to make it faster.
