Photo description / processing
NGC6888 (Crescent Nebula)
It was shot for a long time and tediously from 2023 on a leftover basis after the main objects, hence the uneven accumulation. In the end, I decided to process it as is and not wait for the next year to even out the totals.
It turned out kind of okay.
Integration and stars in PixInsight, post-processing in Photoshop and GraXpert. No plugins. My palette based on HOO with added sulfur.
