Dan - they are definately worth sending around. Unfortunately, I don't have any email addresses to hand but if you trawl through the net, you'll find at least some for the likes of Sky and Telescope and Astronomy mags plus the usual web sites.
The skylux is a cracking refractor - a real bargain. And combined with the 20D/TO filter, you've got them working together a treat.
Are you going to try some wide field images at all?
Cheers
Dave
