A few months ago, I set up a reference page about how to determine cardinal directions through the eyepiece so you can add them to your sketches. After setting up the placeholder for that page, I completely spaced-out adding the actual content. I’m very sorry to anyone who followed the link from the Drawn to the Universe article and found nothing there. I’ve finally written the short article for that page. I hope it’s helpful to anyone who needs to know how to determine those compass points. They are a valuable notation for anyone trying to orient your drawing to their own observations or images of the object.
