Canon T3i dslr with clip-on narrowband OIII-CCD filter(FWHM of 12 nm)and coma corrector on Astrotech imaging newt and Celestron AVX mount. Autoguided with SSAG and PHD software.

Any issues? I've been reading mixed reviews. I was looking at the 6 or the 8 for imaging. Thoughts on either?

Go for the 8" if your mount can handle it!!! Remember, for imaging, a coma corrector is recommended.
