Well in this case Ivan, the images copped a double dose of IR/UV cut because I left it on. An old IR/UV cut (Baader) has been permanently 'welded' to the DMK nose cone for 4 years & the second I took it off last night, 1 million dust particles jumped onto the chip so I had to clean the thing before I could do anything. Screwed the L filter on pronto & imaged.
