This is what I finally did.

Based on information received here and the advice from the Televue site I figure that I won't be bothered by the astigmitism on eyepieces under 10 mm which is where my short eye relief eye pieces are. Over that I have enough eye relief in my eyepieces that I can keep the glasses on if I wish.

So I could have stayed with my current eyepieces BUT Explore Scientific has this great sale on the ES 82s. Normally $150 US, on sale for $100, so I decided to replace my 6.4 mm Meade Plossl (2 mm eye relief) with an ES82 6.7 mm eyepiece (14 mm ER). It arrived today.

I have only tried it out in daytime in my 400 mm FL ETX 80. I thought I would do a quick comparison with my 6.4mm Meade Plossl. As expected the FOV difference is huge. And I was pleasantly surprised that the ES 82 eyepiece is smaller than I had expected, which is good. It is smaller than my Meade HD-60 4.5 mm.


I can't use the 6.4 Plossl with my new glasses, at 2 mm eye relief. If I take the glasses off I can see the whole ES 82 FOV. With the glasses on I can't see the whole view but I still see a wider FOV with the glasses on with the ES 82 than I can see with the Plossl with the glasses off, so that is still an improvement if I want to wear the glasses.

It will be nothing but clouds and rain for the next 4 days. I can't wait for a clear sky.
