To me (and I might well be wrong) it looks like you need a longer exposure and maybe zoom-in if you are going to see if those diffraction patterns are even. And maybe do it on a nearby brighter star, especially if you are doing this in live-view with the dslr? Or it might be easier on a computer with some sort of imaging thingery (eg the backyard eos, or I used Canon EOS Utilities which is free)

Hi Chris.
Thank you for your input. I'm really trying to avoid going down the PC connection path ( much to my detriment ). I'm with you on the more exposure though. The focus shot I posed wasn't from that particular session but it was an example of what I am doing so maybe sometimes I'm getting it closer than others. I'll spend more time trying to get it right in the next session and see how I go. Thank you again for your advice
