For white light observing of sunspots your least expensive option is to purchase Baader solar film and make a front-mounted solar filter. You could, of course, purchase a front mounted filter using film that is already made. Baader solar film is better than the inexpensive glass filters.
To see prominences and disk details in the light of hydrogen alpha you might want to consider purchasing a separate solar telescope like a LUNT 40mm at around $600 to $800 or the LUNT 50mm for around $900.
With the above you could mount the solar telescope on top of or side-by-side with the C8 and observe in both white light and the light of hydrogen alpha.
Solar astronomy is fun and has some observing advantages (like it's usually warm out, no bugs, no late nights, etc.) and when the sun is active you can observe feature changes in real-time. Solar imaging is also challenging.
HERE is a link to the LUNT solar telescopes page.
