thank you!
Indeed I usually don't have problems with low saturated images, so it was no effort for me to keep it low. Most times I have to force myself to put in enough saturation
Thank you for your advice regarding the mounts. Good luck, that you have experience with both of them! I already saw in your image posts that you have excellent guiding results with your EQ6-R
. I'm wondering, how this guy on AstroBin (pls. see Stefan's post above) is able to get such excellent results with his 10" newt on top of his HEQ5?! 
Best regards, Dietmar.
Edit: off-topic: Martin, I assume you're a Star Trek fan? Next weekend, we have a Star Trek convention here in Germany. It's only 30 minutes away from me. Unfortunately a long way from Down Under ...
