(*) Well, I'd like to be an astronomer (having a degree in the subject, 2 telescopes (130 mm reflector and 100 mm refractor), and a plethora of binoculars from 10x42 to 20x80). However, I live in Glasgow, the land of perpetual nighttime cloud, skyglow bright enough to read by, and petawatt street lights. ☹️
