I'm not sure when it was added, but this morning while texting with a fellow CNer about tonight's possible observing opportunity, I noticed that Astrospheric has added a new feature called the Astronomical Clock.
This is a 24 hour clock graph that displays the planets and DSOs based upon their elevation above the horizon. It takes a second to get use to the display as it's not the most intuitive thing I've ever seen, but I quite like it. Targets can be added or subtracted based upon user preference, and there's the entire Messier, NGC, IC, and Abell catalogs to choose from. Dec & RA points can also be used as well.
I think it's a pretty neat feature, and I'm glad that Astrospheric has been adding more. I'm using the paid "Professional" version on Android, but I assume it's also on their web and iOS versions too. Not sure about the free edition tho.
