Startools is a set of tools that allow us to obtain the best possible result of a photograph.
Imagine a piece of wood and some tools to carve it. The goal is to get a figure and each tool will help us if we know how to use them in the proper order.
The first thing to do is prepare the image. Open the JPG image from your camera and adjust its maximum size to approximately 1852 x 1385 pixels with BIN. In this way the program will works faster and the detail is maintained. Then we will eliminate the side artifacts of the stack or the chip itself by making a CROP of 20 pixels per side. Now the image is ready to begin to eliminate all the signal that is not the object itself.
Will continue.....

We already have our photo ready, now we will see what are the main problems to be eliminated. We are going to do this with AUTODEV.AUTODEV is one of the most important tools of Startools, the final result will depend on its good use. This tool stretches the photo to the fullest and highlights its main problems, electronic noise, vignetting and dust spots. Everything we will have to eliminate to get a good picture. We must be attentive then. Nebula and galaxy-type objects that have complex structures must use the ROI option and select the most interesting part so that AUTODEV looks for the optimal result where more detail appears, with stars or open clusters it is not necessary to use ROI. We will always try to darken the background to the maximum with the IGNORE FINE DETAIL option Streched with Autodev Using ROI and Ignore Fine Detail Image with Autodev done

In the image we have after applying Autodev we see some of the defects that we will have to correct with Wipe. There is a slight vignetting and electronic background noise as usual in all photos. We will apply WIPE and select the Vignetting option by setting the Dark Anomaly Filter option to 4 and will say DO. Image after applying wipe

Now we will reveal the image with DEV after accepting REDO GLOBAL STRECH. We will set DARK ANOMALY FILTER to 20, GAMMA to 1.05 and adjust DIGITAL DEVELOPMENT until the bottom of the sky begins to turn slightly bluish. We will confirm with KEEP. Imagen después de aplicar DEV

If we zoom in on the image we will see that there is still a lot of background noise, this noise can be greatly reduced by applying the FLUX tool and accepting the KEEP MASK option Once inside the module, we will select NOISE and set FILTER FUZZ to 2.0. Accept with KEEP as always. By zooming in the image we will see selecting AFTER / BEFORE the effect of this tool. Image after FLUX/NOISE

It's time to adjust the color. The COLOR tool makes an automatic white balance and adjusts the colors of the image. Once the parameters are correctly indicated as seen in the screenshot, we will click on SAMPLE and then on KEEPImage after COLOR tool

The last step is to make the final DENOISE. From the main Startools window, click on TRAK and then on Stop tracking and do final noise reduction. In the next screen choose GRAIN SIZE = 10 pixels and click NEXT.The parameters of this tool are those seen in the screenshot. They serve for most galaxies and nebulae. The clusters and stars have similar ones but they are not the same. And these are the important steps. Later we can increase the contrast with CONTRAST, sharpen the image with SHARP, increase the light of the objects with DEVELOP, repair drowned stars with REPAIR, modify the color of the individual object with MASK + COLOR or with FILTER and much more.
But we will talk about this later if someone is still interested...... Imagen final del objeto

If someone wants to make a comment, they can do it in a separate thread, this can be left for the workflow.
This work system admits variations according to the type of camera or object. It is best to test and publish the results and doubts. In this way we will all move forward and learn something else.
