ES 24/68 vs Hyperion 24

I think the recess is for the waterproofing seal around the eye lens. 

Plausible except that the depth varies from eyepiece to eyepiece, and it seems unlikely some have massively thick seals.

What about eye relief and comfort?  The ES versions tend to recess the eye lens for no apparent reason whereas the Meade/Maxvision versions have them nearly flush mounted to the top of the housing.

I tried both with glasses on & off. Eye relief on both is just passable if using glasses. Without glasses, both are goof for eye relief. The ES version has ever-so- slightly less eye relief with glasses compared to the 24mm Meade 5000 SWA as seen below because it is recessed. I removed the bulbous cover on the 24mm Meade 5000 and gained a bit more eye relief, but again, better without glasses.

Wow, I've not seen one of those in the flesh and so had never noticed the "seal" before.

Had a peek at the Pleiades last night with my ST80 and ES24/68. I previously tried this with the Hyperion 24 and the view was so bad as to be almost upsetting - most of the field was just fuzzy blobs. With the ES the whole field was sharp and clear. Unbelievable difference.

I use the Hyperion 24 with my Equinox 120ED which is f7.5, and it works very well, some edge distortion but nowhere near enough to bother me in use - though we all have our own standards of what is acceptable.  It worked even better on the Tak 100mm which was f9.  From memory I also found it satisfactory on mikeDnights 100mm f6.4 Tak, and I'm happy using it on my Equinox 80ED which is f6.25 or there abouts.  I would think it's worth trying with any telescope over f6 if anyone considering buying one so you see what performance you'd be getting.  I'd expect the ST80 to be a step too far.

The Hyperion 24 is my most used eyepiece with the 120ED for sweeping, giving a mag of around x36 and field of 1.8 degrees.  Very comfortable for spec users also. I wouldn't mind a second one for use with my binoviewer!

I certainly had no complaints about the Hyperion range at f13; I felt they were superb under those circumstances.
