I have used an 80 mm refractor and many sizes up to 16" from my home location. In a light poluted area I can see the same things visually with the 80 mm and the 16". The improvement with the 16" over the 80mm is only marginal except for planetary viewing.
I now can use an ETX 125. From a dark location like Crago only 40 Km away it can see DS objects plainly that I can't see from home with a 16". I have now sold the 12" and my observatory and set myself up for easy portable operation. I also use a 10" LX200 as portable and I can set it up for Full operation in the field in as little as 5 minutes. The 16" is too heavy for me to use regularly so it only gets used on special occasions.
