    Compare the sizes of galaxies and nebulae with the moon!
    Want to know how light pollution will affect deep sky objects in your area?

    It's very useful if you plan on buying a telescope and you want to know how deep sky objects will look through it from your area.

    What you can do with this app:
    Choose from over 100 of the brightest clusters, nebulae and galaxies and compare their angular size with the full moon
    for a precise estimate of how large that object will appear in your telescope!

    For an accurate calculation of how bright a particular galaxy, nebula or cluster will be in your eyepiece, first
    enter the aperture of your telescope, turn 'Light Pollution' on, and choose which of the 5 light pollution levels best describes where you live.

    All statistics and numbers have been fine tuned to give an accurate measurement of how the object will look through
    your telescope.

    All deep sky objects have been resized to precisely the size they would appear if next to the full moon.

    You don't even need a telescope to make good use of this app as over 30 of these deep sky objects can be seen with
    the naked eye(Including 5 galaxies!)

    Extremely useful for astrophotogrophers, amateur astronomers and star gazers alike!

    Know of a bright deep sky object that isn't in this app? Let me know and it may be included in the next update.

    Dark interface for night use
    -All 110 Messier objects
    -The brightest NGC objects
    -Simplistic user interface
    -Autosaving settings
    -Accurate light pollution predictions
    -'Show Moon' button that places the moon beside each object for angular size comparison

    Tip: To get the most out of the light pollution aspect of this app, use in a dark place where your eyes can adjust to see the faint objects on the screen!

    Sometimes when you tap one of the icons it does what it's intended to do, but most of the time it's no go. I expect an app that you have to pay for to work, at least reasonably well.

    the pictures shown compared to the different skies are just darkened the better the chosen sky is. thats not an exact compare to what you'll see wenn you look through your scope. light pollution behaves different than just brighten or darken a picture. considering that all the example pictures in the app are colored. and there are no colored pictures in your scope! not even then when you look thro
