This was a special project.
I took about 70 hours this year 2023 and integrated them with the additional 70+ hours from last year 2020.
There were three different telescopes, three cameras, and two sets of filters, more that 100Gb of raw data.
Evaluation formulas were used to make the integration of the best images more intense than the lower quality ones to get the best possible result.
Also the processing techniques have improved a lot in these years and of course my skills as well.
Sh2-132, also known as the Lion Nebula, is a stunning emission nebula located in the constellation Cepheus.
This celestial marvel is part of the Sharpless catalog, a compilation of H II regions, which are clouds of ionized hydrogen where star formation occurs.
Sh2-132 spans approximately 320 light-years and lies about 10,000 light-years from Earth.
Its complex structure features bright, glowing regions of gas and dark, obscuring dust lanes, sculpted by powerful stellar winds and radiation from massive young stars within.
