I remember trying ngc300 with my ED100 and abandoning the project. Then I tried with an 8" F4 Newt and got better results. But you need dark skies with good transparency.
Here's mine from October. 8" F4, 486 x 30 second subs. Here's a single unstretched 30 sec sub to compare. Unmodified Pentax K-5.
