Hello Carles,
I do not believe that I have received an email from you. Try using the contact form on my web site.
Let the equipment tell you which magnitude stars are good. Look for stars that have a strong signal, but not so strong as to be saturated. Sort of the middle brightness stars on you image. You can compare them directly to the SkyTools model via the Advanced Exposure calculator. Use the interactive atlas to determine what star it is that you have captured and then enter that as the target in the advanced exposure calculator. It is important that the settings be exactly the same as that for the image, including the date and time. For now just compare the signal calculated o the signal you measure on the image. As a starting test it just needs to be in the ballpark.
