Stark Labs provides software for amateur astrophotographers designed to be simple and easy to use. They are designed to be user-friendly and to make capturing your images as easy as possible while still providing the flexibility and power you need. Nobody likes standing outside in a cold field, spending time with gloves off fighting with an awkward user-interface.  I know.  I've done this. At the same time, nobody wants a program that is simple to use, but too limited to be of real use. Here, you'll find Nebulosity, a cross-platform capture and processing application designed to give you powerful, purpose-built tools for DSO image capture and processing - the tools you really need to produce fantastic images. You'll also find a wide range of free utilities like PHD Guiding that make astrophotography easier and more enjoyable.
