853 second sprinkler image
853 second image
Comet Tuttle is displaying a lawn-sprinkler shape as our vantage point is just right to see it face on, much like a spiral galaxy.
It is difficult to see in normal images. The image on the right was derived by taking the difference of two images that were taken
a couple of hours apart.

Larger Image - The jet activity seems significant making for some interesting shots. The jury is still out as to what may have caused this explosion. Comet Holmes is turning out to be quite spectacular.

The image above was obtained using a Celestron 8" F/5 with Stellacam II at prime focus, and color filter wheel and is comprised of:
L 50 4.2 second Broadband filtered images;
R 50 4.2 second red filtered images;
G 50 8.55 second red filtered images;
B 50 2 second blue filtered images;

All images dark subtracted then stacked in Registax and LRGB'd using Adobe.
Color levels were tweaked so that the result closely matched what I visually
observed using a 8" F/6 @ 48X

Holy Crap, what a comet!
The jury isn't out on what happened.
I easily was able to
see this as being larger than stellar with the unaided eye. It is gold and of appreciable size in the finder.
This image is a combination of a few hundred dark subtracted half and one second images, shot with a StellaCam II at prime focus
of a Celestron 8" f/5 reflector.
