Hi I have a WO z61ii + adjustable flattener set to 12.9 with my canon 700d I am going to add a 2” light pollution filter, please can you tell me if and by how much do I change the flattener adjustment, thanks

Thanks John, yes they are the screws I were trying to move.

When I look for the 'doughnut' shape when out of focus on a star it looks like it does need collimating, however i have got a reasonable result from some amateur photography thru it so maybe just leave it alone.

Thanks for quick reply, there are just 3 screws don't appear to be any lock screws, they are philips head screws not hex. Thanks anyway

Hi, Please can anyone help, I am trying to collimate my Celestron 6se, it is a little bit out, but the adjustment screws are rock solid. I have had the scope from new for about 6months and this is the first attempt to try collimating, if I try too hard it is stripping the head of the screw. Any advice please.
