ZWO EOS-T2 adapter backspacing?

Has anyone had success reaching proper backfocus using ZWO's EOS-T2 adapter?

Assuming for all Canon lenses they use the same backfocus as 55mm? I believe Canon cameras require 44mm though?

What does your imaging train look like to achieve this?

Thanks in advance!

Hi,

The backfocus of Canon lenses is 44mm. There is the attachment for your reference.

Thanks!
