It's superior, no question. It can take far more frames in a shorter period of time, meaning you can capture the moments of good seeing.
The only good thing about the DSLR is it's wide field of view at prime focus, when compared with the Toucam. So taking full or whole moon shots is much easier.. but you can make a mosaic with the ToUcam and the result will be much better with a higher resolution (if done well
)
