They tend to be more like port holes to the heavens than just eyepieces.. Windows to outer space crazyeyes.gif  What eyepieces do you own with relatively large eye lenses?

All of mine do...

 

35mm Panoptic

22, 17, 12mm Naglers Type 4

8mm Delos

 

Also have a 17mm ES92 on the way. That may be the winner.

Big EYE LENS EP's --- I'll take a "pic" and send it -

 

Celestron  50mm Axiom (early type circa 2003/2004) - largest 2" EP eye lens I have ever seen and the EP delivers perfect images with my F10 SE8.  Considerably larger EYE LENS lens than Meade 56PL, T/V 55PL, than all the shorter FL 100 and 82 degree EP's.

 

Thing is truly a "window into space".  Throws up incredible crystal clear high contrast views right to the edge.  The ER is like 37mm's so I initially thought that "this just might not work out".  On the contrary - it's easy on the eye, no black-out issues.  

 

Only thing I have ever looked thru that compares (view impression) is HP BINOCULARS.

 

Makes the eye lens in my 27mm 2" Panoptic look SMALL - very small.

 

Has a fold up eye cup but with this thing's ER --- you need to use your hand(s) !!!!

 

M11Mike

 

PS: I'll send a side by side with my 27 2" Panoptic - dwarfs it in eye lens diameter.  DWARFS IT!!!

I wear eyeglasses and have since I was 12 years old (I'm now 56) so tiny eyepieces were always a problem for me.  Even before wearing eyeglasses, I hated trying to see through tiny peep-holes where the view was mostly obscured by my eyelashes because I had to get so close to the ridiculously tiny peep-hole.  This never made sense to me and I hated trying to view like this.

 

Now I stick with my Baader Morpheus and Hyperion eyepieces and have absolutely no desire to peer through anything smaller although, on occasion, I do use my Orion Expanse set too when I have a third telescope set up.  The Orion Expanse set is the absolute smallest I would ever go with their 20mm top lens.  The Morpheus and Hyperions at around 35mm are much more comfortable.

 

Ideally, I'd prefer even larger than the Morpheus and Hyperions provide.  If budget and storage allowed, 3 inch eyepieces would be even more appealing to me.

"Relatively" large. An eye lens the size of a quarter on an ortho would be relatively large smile.gif

The eyelens of the Baader 17.5mm Morpheus ep is just over 36mm wide, but only +/-32 mm is actually used for the optical path, this ep has 22mm of usable eyerelief.

WOW..

I own the 27 pan. Just looking at the pic,  I thought it was much smaller EP, then I read it was a 27 pan 

Indeed. The Celestron 50 mm Axiom makes it look like a large plossl

So what is the AFoV?  I would have to think the eye relief would be on the very long side but it looks like the eye lens is deeply recessed.

The ES92 17mm is clearly a winner in this category and the view is out of this world.

Not breaking the bank is the Explore Scientific 35mm 70 degree. Discontinued and a little tough to find but I actually like it better than my 40mm Paragon.

The 12 have a strangely bulging eyelense. I may get it next year, unless they make a shorter focal length, which would be more useful for me. A 10mm would be great.
