I found them very easy to use and if you haven't already seen it, I made a
sequence to help those who find the wade through the plethora of info and product names on the Catseye web site a little confusing
(this one album has had 16 000 hits since March 07 - who knows how many tools Jim has sold as a direct result
)
I got rid of the ASA 12" F3.6 three years ago thinking I would never need my Catseye tools again
...lucky I kept them as I have the Orion Optics equivalent of the ASA N12 coming by years end
