EF Eyepieces? What are they?

[badboybubby]

Hello, please can you help me?

Noticed an advert Astro Buy Sell to these EF eyepieces. No brand name but I wondered if they look like they represent good value?

Lyra Optic - Eyepieces

Its the ones at the bottom for £45 delivered. Would this be a good wide field eyepiece for my f11.8 127 MAK? Or would I be better with a 32mm Plossl? I haven't got a clue about flat fields?

cheers

skywatcher extra flat... IF you are buying..it seems a good price

wether they are a good match for your 'scope... sorry..can't help

I think most eyepieces will work well at a focal ratio of F/11.8 so no problem there. A 32mm plossl should show just a little more sky than the 27mm extra flat will.
