I really think you'll enjoy the huge astronomical databases of images in every spectrum available. You can also view Earth and the other Planets highest resolution images. Just know the PC version gives you much higher resolution than the web application. You should also be patient and only click in 3 or 4 magnifications then wait until it updates completely before shifting to a desired target like Lunar lava tubes or Apollo landing sites then click another 3-4 magnifications and wait for the image to update. Very high resolutions are available for Moon and Mars. Also Earth you get really good images of Area 51, Nevada, Dugway Proving Ground and Skin Walker Ranch, Utah that haven't been blurred out like in Google Earth. Lots of images all over the Earth from the ISS super high resolution cameras. www.worldwidetelescope.org
