Query: Hard to Focus Technology

The strange focus adjustment lever is just plain difficult to use. The lever is uncomfortable to reach and adjust. It wasn't easy for me to adjust the focus easily or exactly. This made finding the perfect focus arduous and time-consuming.If you don't have a tripod, get one. You must use a tripod if you want to enjoy a long, steady, still gaze at your subjects.I'm buying a telescope next.
