Nice. Really get the impression the comet is on a mission to get somewhere fast!

How do you keep the comet still and the stars moving? As sidereal rate would do the reverse?

Lovely picture.

That's a really great capture.

I have thought of capturing comets using my CCD with separate RGB filters, but that would have the downside, as your pic demonstrates, of having the stars shown in multicolours due to the comet's movement. For that reason I usually use a DSLR or CCD in mono. How do you image a moving object with RGB filters, and still have the stars in their natural colours too? I've seen it done, but no idea how.

A comet traveling at warp speed..... 

Great work .

Could be totally wrong here but im guessing its done by blending multiple exposures. I.e they expose for the comet and then separately for the stars, process both separately and then blend together in PS or similar. Be tough though as i would imagine blending the comets tail in would be tricky, but doable.

Very nice, great details in the tail!

Or is it guided using the comet and three exposures RGB which is why the stars are streaked in the three colours?
