Hi all,

My name is Bill Cotten and I have been lurking here for a week or so. About
the polar alignment scope for the G-11....... I just bought my G-11 in
December and it has the reticle in the polar scope that does not match the
sky. I was unaware that there is another version available. Can I get the
one I have replaced with the "right" one or do I have to buy the correct
one. I asked Celestron about this and was told that they are aware of the
problem but offered no other info.

Just for the record, I use an C-8 mounted on the G-11 and I usually shoot
through an old UO 80mm refractor kit. I also bought one of those ITE 100mm
semi-apo kits. I just received the tube rings I needed to mount the 100mm on
my C-8 but have not had a chance to shoot though it yet. I have given up on
shooting though the C-8 because of mirror slop. Until I find a solution for
this I will just use the C-8 as a guide scope. I have only been shooting
astro pics since Hale-Bopp graced our skies but have had some very good luck
so far.

This is a great group and I'm glad to be a part of it.

BTW, You will probably think I'm nuts but I acually *like* manually guiding
long exposures!! After one or two in an evening though, it seems that all my
guide stars become "variable". :-)
