M1 The Crab Nebula

Supernova Remanant in Taurus

Uploaded 12/31/2000

This is a bit noisy attempt at getting more filamentary detail in the crab, by shooting the luminosity exposure with the red filter. This it is a "RRGB" exposure. I think more can be had in the future by increasing the number of luminosity frames. One of the two close stars in the middle is the supernova progenitor.
