This image was created with data captured across 7 nights from October to November using a 8” Ritchey–Chrétien reflector telescope and a cooled, monochrome camera with both narrowband and broadband filters.⁣
⁣
The Hydrogen Alpha, Oxygen III and Sulphur II emission wavelengths are exceptionally strong in this region and I mapped the colour palette to try and make something truly unique! I belended in RGB stars for good measure. I hope you like it! ⁣
