As the title says.  I need to connect my Canon EOS “L” lenses to my ASI2600MC Pro.  It looks like I can use the new ZWO EOS-T2 Adapter and the website says I can use a 2” filter but there’s no mention on where it attaches.

I would like to use ZWO’s Filter Drawer (below).  It looks like I will need the EOS Lens Adapter for EFW also (below).

The ASI2600 MC Pro back-focus is 17.50mm and the Filter Drawer thickness is 25mm.  I can’t find the thickness of the EOS connector.  How can I connect the necessary parts together to equal 55mm?

 

Is there another Canon EOS to M42 connector that has a filter drawer?  The Starizona Lens Slider is outside of my price range.

UPDATE - It looks like the width of the EOS Lens Adapter for EFW is 17.5.  This gives a back focus of 56mm and not 55.
