Spacers

New guy (dumb like box of rocks :) with all new stuff right out of the box

SV70T with field flattener

1600MM Pro / EFW8

Camera is screwed into the EFW

Flattener is screwed into the other side of the EFW

I assume I need some spacers (from reading various articles)

In the box (plural) is a 16.5mm spacer, some kind of male to male adapter, 11mm spacer

Now, none of these spacer/adapter will thread onto either the camera, the EFW, or field flattener so I assume they for for something I am not using.

Question:

What spacer(s) do I need and where in the image train do they go?

And what thread diameter should they be?

AKA box of rocks :

Seems the best answer Stellarview has is 28 or 29 millimeter spacer between the filter wheel and the flattener..

In the box, 16.5mm extender is male to female threads, and 21mm extender too.

there is also have a very thin M48-M42 adapter, can be used on flat lens.
