While you're here, how about checking out the Astronomy Book List ?

Thank you Chris, it´s a pity JMI doesn´t have a Webpage,
I´ve read about their focusers in its S&T advertise, but I
have no idea which one is appropriate for my scope. Price
range is from $88 up to $250!!

I was doing just the opposite, I´ll try your suggestion
next time. Thanks again!
