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.

Nebulosity has gone open-source and free. Here is a code to unlock Nebulosity if you don’t download the open-source build: N4-14627-55834-23500-59673

Upgrades, etc. can all use that code. Really, just type in
N4-14627-55834-23500-59673 in the license code box and you have the full version.

Nebulosity will be free in November.

As noted below, Nebulosity is going open-source. I’ve tried to give people some good heads-up warning here, but this is the last one. It will be free starting in November. I will post a free code up here and the code will be up on GitHub.

(July 16, 2021)
Nebulosity is turning 16 years old this fall, having started back in 2005. Those were the days of Window XP, OS X 10.4 (Tiger), and my now college-aged child being not even 2 years old. It’s grown from “a simple capture application” for the SAC-10 camera into a full-fledged application based on over 71,000 lines of C/C++ code written by one developer. It’s time now for its next major evolution. Just as PHD Guiding morphed into PHD2 with the OpenPHD project, this fall, Nebulosity will be going open-source.

When that happens, I will stop selling licenses and will have a free version posted here. This will still take some time, but I want to be as open with users as possible. If you can wait and want it for free, wait. If you want it now and want to make sure you have a working version of it that doesn’t rely on my open-sourcing efforts, buy it now. It’s entirely up to you. But, rather than just flip a switch and have it happen overnight, I wanted to give people as much lead time as possible.
