The powerful 'Auto' function quickly and autonomously isolates features of interest such as stars, noise, hot or dead pixels, etc.
For example, isolating just the stars in an image is a necessity for obtaining any useful results from the 'Decon' and 'Magic' module.
The type of features to be isolated are controlled by the 'Selection Mode' parameter
Some of the selection algorithms are controlled by additional parameters;
Finally, the 'Source' parameter selects the source data the Auto mask generator should use. Thanks to StarTools' Tracking functionality which gives every module the capability to go "back in time", the Auto mask generator can use either the original 'Linear' data (perfect for getting at the brightest star cores), the data as you see it right now ('Stretched'), or the data as you see now but taking into account noise propagation ('Stretched (Tracked)'). The latter greatly helps reduce false positives caused by noise.
StarTools is a new type of image processing application for astrophotography that tracks signal and noise propagation as you process.
To only brighten the image (for example if you wish to bring out faint H-alpha, but nothing else), set this parameter to 0%/ 100%.
The noise signature of the deliberately left-in noise, is precisely shaped to be aesthetically pleasing for precisely this purpose.
A 'Dark Anomaly Filter' helps the automatic black point detector ignore any dead pixels.
The FilmDev module effectively functions as a classic digital dark room where your prized raw signal is developed and readied for further processing.
You can convert everything you see to a format you find convenient. Give it a try!
