Touch the focusser and all hell breaks loose.
If I need to start building piers,buying or modifying focussers etc. to steady a pissy 8 inch newtonian, then I have truly wasted my money..........this is not for me.
Shane,...........I would like to return the mount.....even at a loss despite the fact that it's virtually brand new and unused.
I'm not happy with it,will never be happy with it and will never be able to afford a Titan or AP1200 as a mount..........that's ridiculous.
If I had known that it would come to this and was aware of the mount's limitations,and the reality of massive mount requirements, I would never had gone through with the purchase.

um they all do that especially when you touch them to focus (unless you have a motorfocus. i think you are have your self believing these things are rock solid and dont move at all - not the case they do - it then comes down to how quickly the dampen out of the system. if the load is far to heavy they seesaw for a while but do steady down. wind is always a issue - you get used to that and even in a observatory you can get the occasional gust that is a problem. I think you are after a perfect mount and scope - doesn't exist (metaphorically speaking). high end mounts dampen out the jiggles really quickly. your mount should really be suited to the 8" and a guidescope - it is a staple "diet" for the mount for imaging. i use a 127mm refractor with 80mm guidescope on my G11 in a dome observatory and get the wobbles with a breeze. It really sound like you have jumped in without thinking about what you want to do and have no practical knowledge of how the mount is performing. I did when i expected my 12" SCT to go on a eq6 - but i soon learnt. its called trail and error and working through the issues - one step at a time. Its taken me 5 years to be able to confidently stuff up an imaging run
so you should be able to do it in a shorter time than me - i was and still am a bit thick
out in the field i use a eq6 and a heqpro5, wind is always a problem, pardon me
you have the perfect setup with the newt and a guidescope - but that is only my opinion. You can always put up a temporary tarp for a wind break - it may help?
