Thanks to everyone for responding. Good to know I am set to observe with what I have.
But if I wanted to see more detail and prominences would I then need the Energy Rejection Filter and an H-alpha filter?
Would it be cost effective to do this with the C8 or to get another scope?
This absolutely requires a big wallet. <smile>
An energy rejection filter for a C8 only uses 2-1/2 inches of the aperture, and is $400.
Then you'd need a special (expensive) solar filter for ultra-narrowband H alpha (a DSO H alpha filter is too wide a bandpass, and not _at all_ usable. It's not a question of quality, they just won't work.). These are $1200, and they're low end.
Then you'd need a Barlow, to slow the C8 down to a higher F number.
It would be an unusual scope to use for this. Since you're not using anything like the 8 inches of aperture, most people go with a small refractor.
There are some scopes that bundle everything together. This is a low priced version, about as low as you can go. $1750.
This is a lower priced example from a popular company for solar scopes. $1835.
Get a bigger one, and the price soars. This 100mm is $8000.
