Location: Ponta Grossa, Paraná, Brazil.
Data Acquisition Method: Personal Telescope Setup
Description and Details: Also known as Fenrir the Dark Wolf, this nebula is rich in Hα, allowing for a slightly different capture approach than usual.
Note: Most of the data was captured in Hα rather than RGB. To enhance the RGB channels, I gathered several hours of luminance (L) and processed it separately before combining it with the RGB data. Only afterward did I blend the Hα into the red channel and use it as luminance.
For color calibration, I used the ColorMask script in PixInsight to achieve the final palette.
Askar 80PhQ f/5.6, ASI533MM, HaLRGB optolong 36mm filters.
HaLRGB Ha=11h15min, L=7h, RGB 1h for channel. Bortle 6 sky
