Good reference, but application lacks polish – Deep Sky Browser Review

The catalogs are complete, but many of the images are old and the application needs some tweaking to support features like autorotate. I suppose it's not a bad value for the price. Users should also note that the images of catalog objects are downloaded from the network server only when they are selected. This makes for a compact app, but it also means the app will grow in size substantially as more objects are viewed and saved locally. iTouch (and iPad users without 3G) located at remote sites cannot use this app to access images of new objects (objects not already downloaded).
