Looking for a good remote that will suit my 50 D for taking multiple frames (as in star trails) for stacking.

I have a Hahnel that will allow off camera flash and remote shutter/blub and so forth, but not able to set it to take multiple exposure's.

Hakka has pointed me toward this but I feel this is overkill for what I'm looking for.

Any ideas or ones you're currently using?

Cheers,
