Brighter processed image at the above site.

Very happy to have another successful verification of automated comet tracked images This comet shows trailing if tracked at Sidereal rate longer than 120s exposures (at 0.84"/pixel).

Regards,
Roger.

That's an awesome image Roger. You can see the tail curving around.
