Thanks all for the comments.
I imaged the same object last night with a WO 0.8x field flattener in place, I only managed 10 x 10mins before the clouds shut down the run. Once I get that stack processed I will post it up for a comparison.
Rob - the corners of the image look a bit dodgy, check out the stars and you will see them looking out of whack compared to the center of the frame. Using a field flattener should correct this, I have a WO flattener which I used last night.
