below average :) 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 through a 25inch scope. the only good thing is the object sizes compared to the moon.
Doesn't really work 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.
Crashes upon opening App looked useful, but upon opening it, screen turns black and exits. I see Horsehead nebula as start up screen, it loads the photos of messier objects, and thats all folks. Hopefully there is a fix for this.
