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
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.
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 KEEP
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......
