TeleVue 12 and 13 Naglers; choice?

[ollypenrice]

Hi,

So transformed by visiting optical expertise is Sir Isaac, our 20 inch Dob, that I feel he deserves a fairly high powered widefield EP to replace the 10 Radian. Can anyopne tell me what's what with the 12 and 13 Naglers seen on this page? Quite a price difference. Sir Isaac is F4.1, FL just over 2 metres.

Thanks in advance,

Olly I can only comment on the 13mm Nagler, I have one and its my best ep bar none. Have not had the pleasure of trying the 12mm.

Am sure someone will give some feedback on the 12mm.

The 12mm is a Type 4 which has better eye relief than the 13mm Type 6's and a larger eye lens - some folk might find these features make the eyepiece more "friendly" to use.

Performance-wise they will be very similar - the 13mm T6 is a remarkably compact package for what it does.

Thanks both. I can get the hang of most EPs but beginners can't always do so. I need to think about this.

With a T6 eye positioning is critical. I never really liked mine, too fussy. The T4 is completely different, really easy to use. I have the 22mm and 17mm and they are like looking through an open window - the 12mm is the same.

I would already have a 12mm T4 if I didn't own the excellent 13mm LVW.
