Folks,
I recently had my Canon 1100D modded and what with the Sydney weather and all recently I haven't really had much of a chance to test it out...
I've attached a couple of shots taken of M42...the first unmodded taken in the Spring and the second more recently. Given the time of year and time of night of the shots, they would have been taken with the object at similar altitudes. Both were decent but not excellent sky conditions.
I've performed a rough colour balance on both (more challenging on the unmodded shot!) and dragged the levels down to the same value at the black end.
I think the difference speaks for itself

but appreciate that M42 is bright, obvious example. Besides all the extra red in the modded shot, you might notice that the modded shot is a little less saturated in the core region than the unmodded. This is because the modded sub was exposed for only 1 minute, the unmodded sub for 2 minutes. However, the modded sub is remarkably bright, even when looking at the raw output, the histogram is only slightly more to the left than the unmodded 2 minute shot, although it is possible to spot a little more faint extension in the 2 minute shot, as expected.
So far I'm pretty happy
