Horsehead Nebula (HaRGB)

Image Title: Horsehead Nebula (HaRGB)

Date image was taken: November 09, 2023

Location: Sierra Remote Observatories

Image Description and Details: If you have ever looked at an astronomy book it's likely you have seen the Horsehead Nebula within its pages. It's a popular target for amateurs but it's also a challenging target thanks to the proximity of Alnitak. In our case, Alnitak wasn't even in the frame and it still left its marks on the broadband data.

Thankfully, it was possible to clean up much of that and this was the result.

Blue 50 mm: 18×600″(3h) -25°C bin 2×2
