Thanks for the advice,
I did miss out a critical component when i was lining everything up for the image of what i had.
I replace of the 21mm spacer i actually have a ZWO filter housing with filter.
While this filter housing is still the same 21mm, i didn't take in account of the thickness of the actual filter itself.
So that there adds roughly 0.5mm
Worked out that i really only need to replace the 16.5mm spacer with a 15mm spacer which was fairly easily to come by.
So problem all solved, now just need to wait until some clear skies to put into practice and see how it performs.
Very much appreciate all the help and advise, was enough to get the mind thinking a bit more.
Appreciated.
Peter.
