i will give it a rip tonight, nice bright star , maybe venus, take a video, stack it and compare them with you guys tonight
It doesn't have to be too bright, I wouldn't do it on venus.

Do it on a medium-bright star, and don't have the gain cranked up too high. Some of the flaring around the star can be caused by overexposure.

It can also be caused by astigmatism - have you followed Geoff's how-to and checked your primary and secondary for pinching?
