I am very happy for you hOughy. I reckon it is the way to go for DSLR astrophotography. I have noticed when the nights are cold in Melbourne at about single digits centigrade the images are almost noise free.
Now you have a good talk to that nice man Scott and do a really deep exposure with Scotts Canon 300mm F2.8 Fluorite and show us all the result.
You should be able to pick up very weak nebulosity!
