Ross, thanks. I will have to see if I can make out Saturn's moon, Hyperion, mag 14.3, my next time out. Since the theoritical limit of my scope if 14.7, that...
Thanks. The formula gives a 14.7 limiting magnitude for my 10" newt and 12.5 for a 90 mm. As to Encke, the article was interesting, but I wonder if it clears...
