I guess it is a neutral filter. Can I use a H alpha filter in my eyepiece and get better views and pictures using the eyepiece filter.
Many thanks, in anticitation,

In the hope of seeing Prom's and surface filaments... in a word no. Your
EP H-Alpha filter works on a different set of emission lines to one that
can allow you to observe these features on the Sun. Bottom line is if
you wants to see prom's and such you need to get a PST or similar.
The front filter you have only allows you to observe sunspots and possibly
hints of surface granulation. Dont use you SCT on the sun unless you
have that front filter in place. And btw, if you ever see an EP filter
that's called a solar filter to be used on the Sun, steer well clear of
it. These are highly dangerous as they crack under the intense heat
(like putting glass under a powerful magnifying glass). This can blind
you in a second.
