M1 Bi-color (Dec. 2018)

This is M1, the remnant of a nearly 1,000-year-old supernova. If you look closely, at the center of the nebula you can see two stars, very close together.  The dimmer of the two is the pulsar, what is left of the exploded star.  This image is 10x1800" in Ha and 11x1800" in OIII with the SXVF-H9 through the Synta-ONTC 8" at f/4.95.
