Joe,
That sounds like a great choice to me.
If you like eyepieces with longer eye relief or wear glasses when observing the 17mm Nagler T4 is the best choice in this focal length range. Be aware that it is a 2" eyepiece and you cannot use 1.25" accesories like filters or barlows with it. If you dont need the longer eye relief the 16mm Nagler T5 is a great 1.25" eyepiece and the 20mm Nagler T5 is a great 2" eyepiece. The 20mm Nagler T5 is a superior eyepiece to the 22mm and 17mm NT4's IMO but it has less eye-relief. It is sharper on and off axis, has better light transmission and contrast. However, if you want the longer eye-relief and comfort, the 17mm NT4 is a superb eyepiece and the best choice.
