This post is no longer needed, I have "upgraded" the now obsolete (it WAS mono) camera back to the supplier and have a new 314L+ Colour CCD which actually has Colour CCD printed on its sticker.
First impressions are good, as per the attached image taken last night (6 mins exposure only, 6 x 30 secs and 1 x 180 sec, no darks or flats)....a VERY clean camera this one....love it!
So, all good, as you were.....
Cheers
Chris
