In your opinion, what are your top 5 things to observe through a 12 inch telescope that wouldn't be all that good through a 4 inch telescope. I don't want any suggestions of things you could see with a decent pair of binoculars! :) I can readily access Bortle 4 skies. Maybe even lower a couple times a year. I have had a 5 inch telescope, and spent significant time with a 10 inch dob, but that was right outside of an airport, so way too much light pollution haha
