This is an update of my sequence showing Comet Holmes passing close to the California Nebula (from February to early March). The last shot seems to show considerable fading, so this may be my last shot of Comet Holmes.
In the next few days, moonlight and progressively later sunsets will be brightening the sky, obscuring views of the the comet. The next opportunity to photograph the comet without the moon in the sky will be in late March, by which time the outer shell of the comet may be too dim for a photograph.
