Anyone ever use a UHC on an ST80 when doing EAA?

Most broad band filters and narrow band filters require larger apertures. However, it does not mean that you won't see anything in the scope using a UHC filter. I use an Ha filter in my AT60ED APO telescope and occasionally use my UHC filter too, with my OSC (One Shot Color) camera. You can always experiment and see what it does for you. If you have a filter, by all means go out and try it. If you are asking before purchasing, I would say borrow a friends and see if you notice a difference. Light pollution filters will definitely help with light pollution and will bring out detail that you can't see with out a filter. However, with a smaller scope, you won't see a big picture in your telescope, unless you really boost up the magnification of your camera with a barlow.
