ES 14mm 82 vs Nag 13 T6
Posted 11 October 2013 - 09:17 AM
I'm still puzzling about purchasing a pair in the 13-14mm range for my binoviewers (Siebert BN25) and I can't make a choice.
I already own a pair of 24mm Panoptic and don't use any ocs/oca for focusing as I have shortened my truss poles on my dob, so I get x62.5 mag.
I read a lot of reviews and comments about the ES 14mm 82° and they seem to perform very well, compared to the Nag 13mm T6 twice the price !
Ok out of stock everywhere but I can wait if it's worth the shot. I can also find a used pair of Nag13.
I own a dobson 12" f5 and I heard about FC with the ES 14mm, mixed comments about it. No same focus point in the center and the edges, about 30% which is huge !
If so it's too much trouble and I'd rather put more money on the table and get a pair of Nag13.
ES 14 has more ER than Nag13, cheaper for sure, but what about FC with my scope ?
Has someone tried to use the ES14 with a bino on a f5 or less ?

The other good choice would be the Meade HD, Celestron Xcelx and the AT from our host. All have about 60* FOV and are under $75.

But I'd rather sitck with 82° FOV as I also want to use it in mono mode.

I also compared the lower ES focal lengths with the corresponding T6's, and preferred the ES 82s in all cases. However, I thought the 13mm T6 was the best in that line.

Slack, are the ES 14mm more comfortable to use ? In which way ? What about field curvature on f5 ?
Any feedbacks about the UWAN 16mm ?
Clear skies !

ES 14mm seems to be the best value, but I can't stand field curvature, so my choice will be uwan 16 or D14.
