Thanks Merlin!
So much better looking at a graph rather than a description of a graph.
First noticeable thing is the secondary unwanted spike of all colours
up in the IR.
That's obviously screaming out....'must be used in conjunction with
an IR block filter'
Also, just as I have read somewhere ages ago, the Meade IR lets in
slightly more of the IR than the Baader as seen on your graph.
Thanks again, PM sent re email,
regards,
Steve B.
