Ditto what Dave said. $795 will buy you a 10 inch dob with some left over for extra EP's and accessories or with an extra $100 added a 12 inch, there's no substitute for aperture and something that's not go-to will force you to learn your way around the skies. Compared to the 4se a 10 inch dob will have roughly 6 times the light gathering area. Ultimately after the initial wonder of the go-to wears off you will be left with a hunger for more power and your ability to view faint fuzzies with the 4se will be very limited.
