Hi Carlton, Thanks for the feedback. For this image we used the Bahtinov mask as you suggested. We used it and focused with the mask on a nearby star which looked spot on with the spikes exactly centred and then moved back to the moon to take the subs. We're not sure if this is the correct procedure. If it is, then we're not sure how to improve our focus more. Maybe there are other issues affecting the sharpness. The collimation was checked and its as good as we can get it.
