Catseye autocollimator
Hi, I am just interested to know if any has used these
Catseye autocollimators before and also where to get them from?
I have done a far bit of looking around, but yet haven't really found anyone here in Australia that sells them.
It is to be used on a Skywatcher 16 inch Dobsonian.
Any information would be greatly appreciated.
Thanks.
