Thanks Guys,
You might be on to something there Bert, might make up some spacers to go from the cell to the tube wall and see if that helps?
Gary, the focuser is very rock solid so thats no issue. the primary has 3 side clips but they actually don`t touch the mirror as I left like .5mm clearance top and side. More of a safety thing I suppose incase the silicone lets go the mirror won``t go too far. With the primary cell the plate behind the mirror is the same as what is visable. Just a smaller triangle with 3 springs in between them. To this the 3 polycarbonate disks are araldited to the top then the mirror is siliconed to this. The 3 locking bolts lock the two plates together so there can`t be any movement with the collimating screws and bolts.. but I suppose there could be some slight sidways movement possible?
Would it be better to support the mirror closer to the outer edge to stop flex?
I positioned the points similar to the program plop, but maybe thats not as suitable for a imaging system?
Thanks so far guys..
