I think perhaps this wasn’t the best target to go for at the time… too near the moon for the colour camera to get anything more (already fighting against light pollution), and not a massive amount of detail in the Ha for the other. Giving up on this one til I’ve either acquired a CLS filter for the 650D, or I get to a dark site to get some better data.
