Another Zwo ASI spacing & filter question

[Danjc]

I reckon I have it about spot on going off this from Zwo. 

So from my SW FF/FR I have the exact setup as the diagram giving me 56mm. In my EFW I have a Baader Ha filter that is 2mm thick. 1/3 of that is 0.66mm giving me a difference of 0.44mm away from the desired 55mm. 

I take it I will be ok with this ?

I think that the SW 0.85x flattener has a m48 thread? I think that diagram is the wrong way around. You don't need the m48 to T2 if the scope side is T2 surely.

For that size of sensor 1mm won't make a difference.

The FF/FR is M48
