Long-awaited from David Knisely. Based on my experience, I heartily agree!!

I kind of wonder about all the little "crosses" in various places in the text (some kind of artifact in the HTML conversion process?).

There's an inconsistency in the HTML. The META tag specifies charset=macintosh (ie. MacRoman) but those symbols are probably meant to be non-breaking spaces (character code 160) in ISO-8859-1.

You can fix your own view manually by selecting an appropriate encoding in your browser: in Firefox, select menu View > Character Encoding > Western (ISO-8859-1).

If the "item.php" script is just serving up a static HTML file, fixing the META tag there would be easy. I don't know enough about the software behind Cloudy Nights to speculate about deeper causes or fixes.

Well,
I have recently replaced all my older Lumicon filters with newer ones. The differences, as David suggests, are not subtle.
After reading between the lines of David's review, I think I'll skip the DGM O-III.
But the DGM NPB really interests me.
Thanks David.
