I use ETX-90PE (for Japan).
I failed update of Autostar(#497).
And, electricity do not reach Autostar.
I want to update my Autostar to latest ROM.
I saw http://www.weasner.com/etx/menu.html.
However, I could not find the method by which I can solve this problem.
Please teach me the method of sending Autostar electricity from ETX-90PE.

Please teach the caliber of Focuser Extension Tube of LXD75 N-6 AT and the pitch of the screw.

I use canon EOS Kiss Digital N.
Is Focuser Extension Tube always necessary to take the photograph?
