If you don't need glasses at the eyepiece the 20mm NT5 is an absolute cracker.

No, dont wear glasses, actually I found and still find my 7mm HD has comfortable eyerelief... just that me darn eyelashes are a tad long. However this is never a problem with the XW's
another thing I find with the XW's is I can swap eyeballs with no adjustment period like I do with the U/O HD's. and I love the way the eyeguard on the XW encaptures your eyeball. Kinda wish they made the 20mm in a 2" version
Dont get me wrong, eyeplacement was only a five minute prob, and I shouldn't really call it a fault, as I quickly got used to it. With the 3.5 you have to use the 20mm eyerelief any closer and it will black out. Still spectacular in reasonable to good conditions. It did surprise me how usable that power has been in condition I would of thought it would breakdown. However at that power it is effected by sky glow and zodiacal light. But then every ep at that focal length would breakdown. I've had the best views of Mars _period_ with that ep
