The illustration describing backfocus distance in ZWO manual on page 15 is incorrect. I have informed ZWO about this error twice but to no avail. Following ZWO PDF manual will result in wrong backfocus, following the one from Teleskopservice in Germany is correct. See my image:

Thanks

Hi Sir,
Confirmed with my colleague, and check the maunal on our website, it was corrected a few days ago.
Are we missing it on somewhere?
No, the manual that is accessable for online reading is corrected, but the PDF version is NOT.
Bernd
Yes, now illustration is correct!
