Morpheus Vs ES92s
How do these EP 's stack up against each other? How are they similar to each other, and how are they dissimilar?
I knowAFOV is how they are different. AFOV aside, what are some characteristics that set the Morpheus apart from the ES92s?

Re: Morpheus Vs ES92s
Weight. The 92s are 3-5x as heavy as the Morpheus.
Size (the 92s are 2", the Morpheus 1.25"). Like a coke can compared to a salt shaker.
Sharpness--the same
Contrast--the same or maybe a slight edge to the Morpheus. Hard to tell.
Edge distortion--obvious pincushion in the 92s, the morpheus vary from focal length to focal length.
Field curvature--about the same comparing similar focal lengths.
Price. The new US prices for the Morpheus are $259, while the 92s are $800. I think they may still be less in the EU and UK.

Re: Morpheus Vs ES92s
The weight difference is pretty obvious, I agree on that.
If the contrast edge to the Morpheus is slight and hard to tell, then it's a toss up. Unbelievable how the ES92's have gone to $800.
Do you think the Morpheus EPs are easier to use than the ES92s, in the sense that the fullFOV comes into view further away from the eye lens?

Re: Morpheus Vs ES92s
The answer to that is focal length specific. Eye relief varies over the focal lengths with the Morpheus (greatest on the 17.5mm).TayM57 wrote: ↑Fri Jul 02, 2021 5:58 pm The weight difference is pretty obvious, I agree on that.

I found the 12mm 92° easier to use than the 17mm. Whether that was an interaction between long eye relief and exit pupil or the 17mm was just a tad harder to use, I can't say.
Suffice it to say, all these eyepieces are long eye relief eyepieces and usable with glasses. The exception is the 4.5mm Morpheus, which I found marginal for glasses use.

Re: Morpheus Vs ES92s
That's interesting Don. I found the opposite to be true. The ES92 17 was easier for me to use, than the ES92 12. I'm guessing this isn't related to the amount of eye relief, but, probably due to the amount of SAEP and my observing style.
I like to hover where the exit pupil is. The flatter the exit pupil, the easier it is for me to use theEP . In that regard, I find the ES92 17 easier than the ES92 12 but the difference isn't significant. To an inexperienced observer like my family, the ES92's would likely feel the same.
I'm looking forward to using the Morpheus EPs. I'm very curious as to whether I'll like the 76°AFOV . The DeLites are great EPs, perfect for Lunar and Planetary. However, for DSOs I naturally reach for the A11/ES92s. I'm hoping the Morpheus will be an addition to that group of EPs that I have.
I looked through Swayze's 31T5 and his Ethos last night. I found that I don't miss the 100°AFOV as much so as long as I have the ES92's to whet my wide field appetite. In that regard, if ES ever released a shorter focal length ES92, I don't think I'll ever be tempted to wear contacts in order to use the 100° AFOV eyepieces.
I have my doubts on whether the Morpheus EPs are wide enough to satisfy my appetite for the wide views. But we'll see, as I have the 9 and 17.5 Morpheus coming in, as i bought them used.

Re: Morpheus Vs ES92s
I find the 17 ES92 easier than 12, wearing glasses. The 12 needs to be pushed firmer against my glasses lens.
Comparing 12.5 & 17.5 Morpheus against 12 & 17 ES92s, I find views are slightly brighter in the ES12, but more similar between the 17s. This may be because at higher magnifications, observing becomes more intense and triggers more alertness.
In any eyepiece I prefer pincushion to barrel distortion, having to choose one or the other.
