JPS,
I own the glamour set of colour planetary filters.
I own 14, beautifull 2" made in Japan, optically superb Hoya colour filters. In just about every colour and shade known to man. These are about the best colour filters you can buy and owe my several hundred dollars.
I VERY RARELY USE THEM AND THEY SPEND THE MAJORITY OF THEIR TIME UNMOVED IN THE EYEPIECE CASE.
As others have said save your money !!!!! They look nice but

PS: I also own 10 1.25" Andrews color filters which I haven't used in ages, these don't even warrant transportation to the observing site as I take the 2" ones which keep the eyepieces that stay in the case company. If anyone wants the 10 1.25" Andrews colour filters for $50 send me a PM.
