The newer Coronado BF30 seems to come in two parts......
The 2" section with a full sized ITF rejection filter
and the 1.25" diagonal with a 30mm blocking filter...
Is this correct? Are there any other filters in the assembly??

Re: Coronado BF30 construction?
Ken there was a thread in the Commercial scopes and equipment section regarding the two part BF30. I'm not sure how to provide a link to it, but if you do a search for 'Coronado BF30 too bright' by FRAZ, you should find it.

Thanks Gus!
Found Frederics report on the BF30
viewtopic.php?f=10&t=21651&p=198539&hilit=bf30#p198539
(The one I'm looking at doesn't seem to have the Red/IR pass element, but does have what looks like a small (15mm) ITF at the nose of the diagonal (like the BF10 etc) - just doesn't feel right!!!
