Description

This is M51 through a hydrogen alpha filter. There is so much Ha emission in this object that this almost looks like a luminance image. Later on, I will acquire broadband images of this target and layer in the Ha data to the final color composite. For now, it looks pretty cool on its own.

Edit: I have created an animated gif illustrating the HII regions of M51.
