Stark Labs Affordable, Powerful, and Easy to Use Astrophotography Software

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.
