This will reduce your exit pupil from 8mm down to 7.24mm. By any chance did you consider the ES 68 28mm which would have given you a 6mm exit pupil?

I used to own the 28mm Meade 5000 SWA, which I found was an excellent eyepiece, and is very close in performance to the ES 28mm 68 and sold it to try out the 38mm Q70 for a wider FOV for star hopping. I am not concerned about "exit pupil" as some are, and the 38m Q70 showed me awesome views of the Veil with O-III and orion UB filters. With the 8mm exit pupil I had, nothing was super bad about it....so I ignored the 8mm exit pupil and used it anyways.
The 38mm Q70 was excellent in regards to FOV and star hopping and eye placement, but edge aberrations were pretty harsh after really looking. I have tried other eyepieces that showed close to an 8mm exit pupil and edges were much better than the 38mm Q70. The 35mm Pan was one of them, but eye placement on the one I tried, (which did NOT have the recessed lens), was a bit tricky.
The Meade 28mm SWA was a lot better edge-correction wise, I just switched over like I said for a wider area and star hopping with it made finding things a lot easier because I could see more stars to hop with, plus larger targets fit in the field better.
The 34mm ES will be the same in regards to star hopping, fitting targets in the FOV and edge correction will be somewhat better than the 38mm Q70, so I jumped on it!

Congrats Markus! I am hoping that the ES68 34mm will be significantly better at the edge of your fast reflector than the Q70.

Curious, Markus, I have a Meade 34mm SWA & am waiting on its 28mm stablemate to arrive shortly 
The 34 Meade is the same glass as the ES, but you may know that already. I've been using it in my 8" f/4 dob (big exit pupil too!) & it is super. Sure some coma, big deal really, but the best thing is other edge abberations are very well controlled in an f/4 reflector. It behaves even better in my 17.5" f/4.5 dob.
Big sucker though, coming in at 785g. I don't know how big the ES version is though. Only a little less I imagine, but I'd like to know the difference between the two. Please, I'd like to know your thoughts how it performs too.
Alex.

Hi Alex,
I just got the 34mm ES yesterday. I was able to try it only once in less than ideal skies and my scope was still cooling when I tried it. I did get a good look at M-45 though it and it is a lot better corrected than the 38mm Orion Q70 I had, but eye placement seemed more finicky in the 34mm ES compared to the Orion. I'm going to have to get better skies or travel to my spot to really see how it performs. I have looked through the 34mm Meade SWA like yours and I was impressed.
I put the 34mm ES on my scale and the weight is 680.4 grams.
Cheers,

I had a 28mm and it was EXCELLENT Markus, I would expect the 34mm to be the same.

5 good nights in a row? That's paradise! We've had at least 5 cloudy weeks in a row.....and from what I've spent dudring this period, I know why.....Think instead of calling it the scope shop anymore, I'll call it Cathy's Cloud Store....

That is too much--you'll get tired out, observing every night. And if you don't observe on one of those clear nights, you will feel guilty. I rather have 5 nights spread across 2 weeks; the week before New Moon and the week after.

No way lol. The 5th night I worked till 11:30 then packed and drove for observing from 12:30 - 4:30 (I had to, to avoid the guilt). Got a nice head start on some of those summer gems.

I'm thinking you started the afternoon shift around 3pm after getting to sleep in, you luck dog!
To keep this thread on track, Markus, what say you about the ES68 28? Are you finding it better in some respects than the 34mm?

I have to agree. We had 6 consecutive nights of outstanding clear skies last week. The first night I was out to 1am, then midnight, then 3am, then 3am the 4th night. And I still had to get up at regular time each morning. I didn't go out the 5th or 6th night because by then my body was so worn out I had picked up a cold.
