I have the opportunity to by a Coronado HA filter at a really good price. I am trying to find an adapter plate to fit my scope. The plates that I am finding that are made to fit the SM40 seem to be mostly fit to Televue scopes. Can a few of you please post the O.D of the dew shields for the Televue scopes in the 60mm-80mm range.
Thanks in advance!!
