I bought mine from Sky Instruments in Canada. I have been happy with them. As I recall, I got one or two more than I would have from Orion for the same price. I'm not sure they have a web site, though. You'll of course pay a premium to filter those nifty two inch EPs that I envy so much... dave --- Richard Tenney <retenney@yahoo.com> wrote:
It sounds like so far the consensus is, Orion filters work well; are Lumicon generally considered better? I think I heard Lumicon will be here for ALCon this summer -- do the items they bring for sale usually end up being "seconds"?
Anyway, thanks guys for your input! Rich

It is important to know that filters don't improve the image wholesale- they just bring out details that are otherwise lost, mostly due to "irradiation"; that is, the tendency for low-contrast details to bleed into one another. If you are expecting something spectacular when using a filter, you will probably be disappointed. There have been times when details invisible with no filter have become obvious with it- but much of the rest of the planet actually suffers. That's the point-removing colors that would otherwise mask a particular detail. Filters are for the details only, not a general enhancer. I use Orion's color filters, not the cheapest on the market, but hardly "top-dollar" either. Brent, one of these days let's get together, maybe I can change your mind on filters. BTW, as our eyes age, our corneas tend to yellow (that's why old ladies sometimes have blue hair- it doesn't look blue to them, but silver) so we eventually get a filter FREE! (Hey, look on the bright side!)

My experience is a bit different than most. I find filters degrade the seeing unless you have paid top dollar for them. My 8" (refractor) has a minus violet filter in it. I don't use anything elso, because they seem to confuste the image too much.
