Thanks. I have an Iphone, can you recommend a nine app(s)? Unfortunately, I live in a city, and there is a big mall with VERY heavy light pollution like 2 miles from me. There is an open space, something like a field with no light at all, but close to the mall I was talking about.
Star Walk and Sky Guide are two very useful star gazing apps. I currently use Sky Guide, but I used Star Walk and both are excellent.
