Are planets annotated?
No. Although it’s possible to compute the position of a planet at a given time, it would require knowing when the photograph was taken. While I do have this information for some photographs, I don’t have it for all of them. It’s also somewhat computationally intensive to compute planetary positions, so I’ve decided to leave them out for now (if a planet appears in a photograph, it’s often mentioned in the description anyway). 2.3. Are Messier and other deep-sky objects annotated? No. I plan to eventually annotate Messier objects (though probably not other deep-sky objects, which are normally too faint to show up on my photographs anyway), but these are not currently annotated. 2.4. How complete are the annotations for stars? The annotations for star names come from a catalog which lists the brightest ~9000 stars; these annotations should thus be fairly complete. 3. Aesthetics 3.1. Why do the labels for right ascension and declination overlap in the middle of the image? Roughly speaking
