    An incredible amount of information is provided in a very clear fashion. It must have been a real labour of love to have put in the considerable effort to develop this. Thank you.

    This is the best star-gazing app I've found yet(way better than google sky). Itt's definitely worth the purchase too... if you're fascinated by looking up into the night sky

    Best tool I've ever had being an amateur astronomer. Using this helps me better locate what I need with my telescope. Hands down worth the price!!
