I found 3 frames from when I first night i got the 8"EDGE these were taken at F10 with an unmoded Canon D7. They are single frames reduced and compressed only no cropping. I didn't have the hyperstar then or the QHY10 but at Hyperstar the images show nice round stars across the field.
These were taken on an EQ6 and i have forgotten how long but from memory about 4-5 mins each. Hyperstar your time per frame reduces down to 30 secs to a minute depending on subject and of coarse the focal length reduces.I was also trying my QHY5 guider through a modified 50x9 finder for guiding and wanted to see how it went at 2000mm focal length.
One thing to remember is the distance from the internal reducer lens and the image plane is critical. Not sure what it is in the C14 but go the Yahoo forums have the distance. If you get it wrong the images will show stars out of focus towards the edge of field.This is at Cassegrain F10.
As of yet i have not tried any planetary imaging as I was looking more for the short focal length wider field for DSO's.
