       Show HN: Astro App
        
       I really like Stellarium and SkySafari but I felt like these are
       primarily geared towards exploring the sky but not so much "here
       are the long list of things I want to see, when can I see them
       tonight and where". There's also not really a great option I've
       found that combines sky object planning + location weather details
       while still being free so I built this. The UI's heavily inspired
       by NINAs sky atlas + Robinhood.  Right now you can:  View the
       altitude chart of objects and 3D view  Create lists of objects of
       interest  View the annual max/min daily altitude of an object to
       find the best time of year to view  See live clouds from GOES
       satellite view + weekly night-centric forecast

       | shooting will be. I also like to know the brightness (magnitude)
       | of each object to help with planning. The last thing would be to
       | get a list of recommendations rather than using lists of
       | favorites. "What deep sky object do I not know about that today
       | would be perfect for shooting?" is a question I have only been
       | able to answer well with the ASIAR's list of suggestions,
       | manually curated calendars online that are not tuned to my
       | location, or social media. It seems like you might have all the
       | data to do a better job than all of those options in answering
       | that question. Super cool app! Excited to see where it goes.
