Well thanks Alex for your contact to FLI..the Filter Wheel is on it's way and I am pleased that part of the equation is sorted. The people at FLI were courteous and prompt to answer my e-mails. Not the ideal solution as I wanted to stick with the same brand as my camera but then I might be a total convert to FLI in the future. Now all I have to do is contact Astrodon for a set of Filters...lets hope for clear skies over the Easter break
