Eta carina and Southern Pleiades ISO6400

Hi all,
As a bit of an experiment I shot a series of 30 second unguided shots with the modified Canon 50d on a SW Pro 100mm refractor using a LPS filter.
With Eta I got 59 subs with a bit of manual dithering and a resultant crop, while with IC2602 I stacked 49 subs and no dithering at all was used. Processed in Images Plus.

I expected to see more noise - so I was happy with the results.
Previously I posted that I had an odd problem with the camera - I had it investigated and seems likely due to low voltage.
