Last night I added 3.5 hours of Ha to the 6 hours of OIII I have on the Cat's Eye. I never imaged in heat like this and my camera did not do a great job cooling so I had a lot of background noise. In any event I combined the data in PixInsight and produced a bi-color image of this interesting target. The eye resolves nicely. Camera is an SX H16 mono and the Scope is a Celestron 8 HD and I used my off axis guider.
