I couldn't tell you wether it is a slewing problem, hot pixels or a meteor but I can tell you that I don't think there are "favourites" on this site that just get cudos for posting.
Just about every image I have seen put on this site has been up for scrutiny and members actually ask for it to be analyzed.
This is not to have a go at you but to learn and possibly take on a minor changes or something mentioned to assist in extracting the best you can with the equipment you have at hand.
Keep on imaging and posting as novices like myself do learn from reading all these posts.
