Yes you can guide with an OAG and a QHY5 on a C11. Bit hard to find a guide star at times but it can be done. A lodestar is best in this case as it's more sensitive. Focus the primary camera first then move your guider up and down to focus the guide star. Problem on the C11 is the field curvature which makes stars on the edges a bit chonky and dimmer.
