I don't know how your email client displays headers, but when I get a message from sac-forum and other groups, the header reads sac-forum-bounce@xxxxxxxxxxxxx; on behalf of; Albert Barr <ajbarr@xxxxxx> My client shows your email address at the end of the line. If I want to reply to you personally and not on this bulletin board, I can double click your email address and compose a note to you.

Paul I am using an FSQ 106 with reducer which gives me 386 mm at F3.6. The camera is a Starlight Xpress H16 with a 2048 x 2048 chip. Not sure exactly what the field of view is. BTW, general question, if you get on this Forum and see comments directed to you is there a way to respond directly or do you have to do it via email like this? Thanks Albert
