Rosette Nebula

crimbfighter · Feb 5, 2024

Here is a high resolution image of the Rosette Nebula! This is a large two panel mosaic (panorama), captured over three intermittently clear nights. The Rosette Nebula is another of the wonderful targets in the Orion Constellation. The first image is true color, and the second image is converted to an HOO color pallet, which highlights the difference between the ionized hydrogen (gold) and oxygen (blue). I also included a cropped in image from the core of each of them. There is some incredible detail in there!

Awesome again - I find the clarity quite incredible, I'm certainly no expert in this field at all but i do have a keen interest in space science - if there pictures were on NASA's website I would think them just as awesome. Must be a very nice feeling for you to see this end result. Super.

Keep them coming!

Thank you! It is very satisfying when one of these images comes out. There's so many things that can ruin it along the way that each have to go well to work.
