Hello to all forum readers and writers.

This post does not contains a great picture like those we are used to see here, but wants to be an homage to all guys of the forum who help newbies to climb PI learning curve.

This picture was taken almost one year ago on a moderately light polluted sky in northern Italy with a more than 30 years old Leika telephoto lens and a Modified Canon 350D DSLR.
It was processed with IRIS and GIMP software: most used commercial software is too expensive for my pockets and software piracy is not an acceptable shortcut for me.

Since first processing the image showed a strong green cast and even with white balance the green hue remained mostly on the tiny stars in the background (they were green like peas  :o ).

Every attempt to correct this hue turned my picture to magenta: after a lot of work I obtained the firs picture showed here: this was my best of.

Then i knew and bought Pixinsight a i began to climb the learning curve thanks to the forum contributors help.
I know that you cannot get diamonds from manure and if you have a poor data set you cannot get an APOD but in my opinion PI has done a small miracle!

The second picture is the final result from the same raw data of the firs one.
Unfortunately the strong green cast has faded away most of the nebula color.

As I said it's clearly not an APOD, but for me is a giant leap!

Thank you guys!!   a great forum for a huge software!

Any advice is welcome!
