You can get rotary ones... can you get horizontal ones?
I have one of these:

Came with my DSI. However... the filters are very firmly emplaced... they're not going anywhere fast
Seems like almost a waste of good filters. Can I get a fitting that will sit on the end of my focuser? Had a quick look... didnt find any
Thanks!
