Thanks very much. I'd love to get the Pentax but that's out of my price range. I'd definitely get the NLV because they're said to be really clear with great contrast. I'm just worried that with a push to dob, the 45 degrees might become an issue. I've read the 82 degrees of the ES can almost fit the whole moon in the eye piece!
Thanks for the ranking. It looks as if I can get the 5mm NLV for slightly less than the ES 82 degrees so that might make up my mind. Thanks again.

I recently purchased an NLV and in terms of simple optical performance on Jupiter was extremely impressed with it. I have also compared the NLV with numerous other EPs (all at 5mm) at my disposal and would rank them as follows.
It should be noted that I found the Pentax to be the clear first/best but thereafter the difference between 2-4 were marginal (basically all almost as good as one another) and thereafter 5-7 werent as good but likewise almost as good as each other.
1) Pentax XW (A)
2) Vixen NLV (B)
3) Televue Zoom (B)
4) Televue Radian (B)
5) Televue Nagler (T6) (B/C)
6) Explore Scientific (C)
7) TMB planetary (C)
