Thanks Paul,
I have the following information so far according to the STXL Operating manual which matches your comment

Mechanical
===========================
STXL Body Only = .997" = 25.31
STXL + FW8G = 2.435" = 61.84

Optical with 3mm filters
======================
STXL Body Only = .958" = 24.33mm
STXL + FW8G = 2.357" = 59.87mm

My understanding is this measurement is without the mounting plate adapter. And following is the unverified information that I have from SBIG group which probably needs to be added to the above if I want the adapter to be threaded in.

"The lip inside the threaded part of the STX mounting plate is .050"
[1,27mm] "


I am waiting for a reply from SBIG as I don't intend to get my calculation wrong.

Regards
Raki
