Yes that is an improvement. If you want to post your raw file somewhere I can see if there's more data in it than what you're getting out. Or, you can e-mail me at
alphajuno43@gmail.com if that's easier. Since you mentioned the jet stream last time, the conditions may not be there for you. Practicing on the moon is good too when it's around. Then you can mess around with focus and collimation and get better feedback. I will usually run a file through registax out in the field to see what kind of a night it is. Sometimes it's better or worse than I think it is. Good luck.
