One more bump! I have researched my previous posts on anything to do with the Colorstar and noted that I had mentioned the two different diffused covers. I was getting help on a bigger issue at the time from several users but only Nick Zentenna replied on the covers( maybe he was the only one to spot the question).
He used the clear spot cover for everything and didn't have the cover I was describing However I noted that Ed Sukach, Mike Wilde, L Gebhardt and hka were also helping. There may be others out there as well.
A source of info on the Colorstar would help. I might be able to see pictures of the different covers so I can identify the one for selective integral measuring.
So anyone out there with a Colorstar 3000 who can help?
