Antares 32mm 2 inch Erfle
      #1424177 - 02/14/07 03:28 PM

I've been offered a good deal on one of these, for use with my GSO 8 inch F6 Dob and Megrez 90 F6.9 APO.

The one in question is the 65 degree one rather than the 70 degree modified erfle that Antares also make (or made).

Has anyone any opinions to offer on this eyepiece ?.

Thanks,

John

I had a 32mm 2" erfle and I used it in my 12" f/5 reflector. It shows significant field curvature or astigmatism, (can't remember which), and if you are hunting for planetary nebulae, you will think that you are seeing planetaries all at the edge of the FOV. Not worth it IMHO.

John, I tested both at Sky Instruments in my 100mm & 120mm F5 refractors. I ended up with the wide angle version but really ended up using it most in my F10 \ F8 scopes. Overall there are better options for not much more money.

I had an Antares Erfle, not sure if was the 32mm or a slightly longer focal length. Anyway, like all Erfle's it was not good in a faster scope and for an Erfle, F/6 is fast.
