SH2-101 The Tulip Nebula
Photo description / processing
The frame distribution across channels is not entirely canonical: hydrogen is assigned to luminance, sulfur to red, and oxygen to green and blue. This approach allowed combining the detail of narrowband imaging with a nearly natural color.
Captured from August 26 to September 4, 2019, in the suburbs of Voronezh.
