I've recently discovered that the published back focus specifications for the STXL-11002 and AOX have changed in the past few years. Assuming of course that this was NOT due to a physical engineering change (which would require me to get specific with my serial numbers), I'd just like to confirm that the most current documentation is correct. The following numbers represent effective (optical) back focus with 3mm filters in place: Element Back focus STXL + filter wheel + filters 2.357 AOX 1.051 AOX spacer (measured) 0.201 Total 3.609 The filter wheel is the FW8G-STXL. Thank you, Jonathan
I got some terrific help from Tim Puckett offline. He directed me to this information which is very valuable: http://www.sbig.com/support/product-documentation/backfocus-table/ Thanks! Jonathan
I enjoyed our talk. We will be updating the manuals and much more soon. Your input was most welcome. Call anytime, was good to see you at AIC. Cheers Tim
Hi Colin, The Archive site has all the older product info there. Each product page has the BFD, to my knowledge there is not a one page chart for older units. http://archive.sbig.com/sbwhtmls/app_notes.htm http://archive.sbig.com/sbwhtmls/online.htm Best regards Tim
