That's nice, when I get a chance I'll put my stuff from last night up.

Mike, don't ask Paul about a colour wheel!

what about if I ask Paul about a colour wheel? Would that be better?

There is a story there, The Canon lens will take 48mm filters and I thought Whoopiee! as I have a set of 48mm RGB filters. But they go in the filter draw of the lens but the apature in the lens that the draw slides into is too small to thke the filters I have. I don't fancy taking a file to the filter holder and I don't fanct de-glazing the filter so I'm going to send them to SRB and see what they can do for me. I'm hoping that they will be back in time for DSC.

NOT!

Do the filters need to let through light in certain wavelengths only? Couldn't you make some filters out of photographic gel sheeting or something?

Kodak Wratten Gel sheets were used by the film boys before commercial filters were availble. However they aren't so good for CCD work because they don't block the IR.

Does that image's presence here mean that your homepage is back online?

No Afraid not, i have been loading images to my NTL site for the past 18 months, but I haven't built the site. I plan to do a full rebuild but that may take a while.
