The backfocus of this camera per the spec sheet @ https://www.sbig.com/products/cameras/stxl/stxl-16200/ is 24.8 mm, but on the Backfocus Table @ http://www.sbig.com/support/product-documentation/backfocus-table/ it's listed as 24.1 mm. Which is the correct number, or are they measuring different things?
Eric, Use this table below. It is accurate. http://www.sbig.com/support/product-documentation/backfocus-table/ We are updating manuals, install guides and product sheets so it will take some time. Regards Tim
