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!!

Sam,

The widest OD on the dew shield on my TV76 measures 94mm, but the front 17mm of the shield tapers slightly, down to 93mm.

The dimensions on my TV Pronto dew shield are similar, but about 1mm less on both dimensions.

Note: The filter threads are on the front end of the scope, not the sliding dew shield.
