Just remember that the large scope is heavy and setup may become more complex. This is why I like to observe with a light bucket. Forget the claims of cheap telescopes. Often the atmosphere around here limits you to 200-250x regardless of how big your scope is. In my experience the best atmospheric conditions around here occur in September.
Field of view Think about it.
The average telescope with the average medium power eyepiece has a field of view of about one degree. There are 360 degrees in a circle and 180 degrees in a hemisphere. From horizon to horizon is about 180 degrees not accounting for trees, buildings and hills. The focal length of the telescope determines your field of view. The larger your focal length the smaller your field of view.
