Geez, here I am having to reply to myself. Seeing as how nobody has replied I presume that these charts are of no use so will remove them soon from the website.
Hi guys, I did Corvus last month for the Auckland Astronomical Society Journal. I have written for them for the past 12 years or so. Steve, I put the article up after I had linked the charts. Anyway, good to see that somebody has looked at them so perhaps others may be as well. I will keep them up a little longer.

There was discussion of the StarryNights (the free version) in this thread.
The problem with it, is it only contains the bright (only 69 of them) NGC objects, so it doesn't have a very comprehensive database of objects in that version.
