>>140781985 inch dobsonian, skywatcher 130p to be exact.
I'd recommend the 150p heritage if you want something very compact. You can collapse the scope, but its stll 6 inches of aperature. That is plenty for deep sky and some details on planets. If you live in a city faint deep sky objects are difficult, but you can always see the moon and planets even from the most ligh polluted places, so for me a smallish scope is ideal.
Lots of people get 8 inch dobsonians like this guy
>>14078208, but those are already quite a jump in size and weight. Stll fit in the back of a car if you want to travel to darker skies
