Coma corrector f5 and zwo

I set the eight inch up with the zwo but have realised I did not include the commma correctorr.
I have read up on spacing etc but wonder has anyone here gone thru adding one to a similar set up.
From all I have read it seems one needs a 7 mm spacer ... I have yet to open the cube and use my new gauge but heck I thought there may be someone who has done it here and can relate their approach.

The only contribution I can make is to say that the SW f/5 coma corrector
does not need any spacers when used with an SW 8" f/5 Newt. I don't know
what brand your Newt is, so this may not help.

Hi Raymo.
I have something cobbled together but nothing to test on and tonight looks crook.

Anyways I crop my images a great deal so if the outter stars are bad no problems as I wont fret too much...
My scope is a GSO F5 eight inch Newtonian.
I used the coma corrector with the nikon and not problems ...it should work out.
