A recent e-mail;
Your FilterSlide is one of the best accessories I can imagine for a big
Dob. It makes the difference between using a filter and not using one
in many instances, because it's so convenient to be able to go between different types of filters or no filter at all. It's also nice not to have to
worry about threading the filter onto the eyepiece or dropping one or
the other in the process. I have one slide with a Deep Sky, UHC, and
OIII semi-permanently threaded in and another with rotating
miscellaneous color filters. RGB would be good for imaging. I hope
you're selling a lot of them; it's a really useful product.
