Everybody - not just members, and not just imagers - are strongly encouraged to submit reports by way of images, sketches, or even without any imagery. You can come up and give a verbal report about the conditions you observed under, the details of the equipment you used, what you'd had for dinner, and of course a description of the object as you observed it! Be sure to send them to me for inclusion in the next meeting at meetingchair[at]ottawa.rasc.ca
