Definitely an improvement!

 

Your collimation is a bit off, you can tell because the bottom of the rings is dimmer than the top. With perfect collimation the ring should be uniform in brightness. 

 

The star Hydor is a good target for collimation right now as it is very close to Saturn in the sky. Collimating in or very near focus is best, out of focus donuts are not helpful.

Getting better, but you really need to extend your bedtime a bit. At your location at 10:45pm, Saturn will be at 39 degrees elevation. Imaging at this elevation will have a huge effect on your images.

 

You are being a little harsh on the sharpening in Registax, try dialling it down a bit. It's also a little dark on my screen, a bit of extra brightness would help. Are you using the settings in Sec 15.1 of the FAQ?
