Star Chart

For someone that would like to get back into "Star gazing" this is an App that can help me get back into a fantastic pastime. The darker the outside environment the more your eyes can gain light from distant light sources. There is so much to look in ore, that if a white light is used to read a map, drawing or notes, your night sight can be put at risk. Having a "Night" red light function means you can keep your night vision, and using the app, you can see a lot more that most of the books l have on this topic.

Sky looks different

After the initial novelty and suspension of frustration, I find it disappointing that the sky just looks nothing like the images this app presents. No, I am not expecting to see actual pictures of crabs and Viking ships in the sky... but at least the visible stars and planets should match up with what's presented - and they just don't quite do it for me: right now I am looking at Jupiter and, in my basic spotter scope I can see what looks like several moons which happen to be in a straight line; in this app they are not shown, or they are in the wrong places.

While bright planets can be found and identified, on the screen they are shown to be closer through gross exaggeration of their size, which I find unhelpful.

Speaking of exaggeration, the galaxies and nebula displayed by the app take the cake. They really take away from the usefulness of this app and make finding things more difficult as one has to mentally suppress the garbage.

Could be so much better.

Great app!

This is a really good star chat app, my only negative comment on it is how occasionally the gps has some issues, and I wish there was options to change the temperature from K (kelvin) to Celsius and Fahrenheit. Other than that it's great! I specially like how it has detailed written information on each of the planets, dwarfs, satellites etc, keep it up.
