Thanks for your input guy's, it will take a while to 'get an eye' for what is a good finished product, I certainly appreciate your 'well tuned eye's' having a glance at my pic's.
Thanks for your link Gary, that's exactly what I was hoping for. I'll give it a shot when I get some time. The collimation of the mirrors is good from what I can tell, I think the problem is in the (cheapish) focuser, and I'm getting some tilt when I screw the locking screw in. I hope that this will help me sort it.
Thanks guy's
George
