    Will have to agree with Carlos; my 1st choice would have been the Baader Hyperion 8-24mm zoom but since zooms are out in this thread, then the Hyperion fixed unit will do for the budget. However, I placed an order for an Explore Scientific 14mm 82-degree series for only $99 because they are on sale right now - compared to the 68-deg. of the Hyperion, the wider 82-degree AFOV will allow you to get a taste of the so-called "spacewalk." Just 2 cents.

    I think it refers to viewing the moon close up, as if you were an astronaut orbiting it. Perhaps other objects, as well, where the field stop is beyond your peripheral vision.

    The "spacewalk" is said to be the feeling that one gets when viewing through wide field eyepieces and was first mentioned by Uncle Al Nagler, the owner and patriarch of Televue (makers of Nagler & Ethos eyepieces), when he was talking about the then newly introduced Nagler eyepieces which was revolutionary at that time for having an unusually wide field of view of 82-degrees compared to the narrower fields available at that time. It's like looking out from the porthole of a spaceship where the view is wider that what the eyes can see when centered at a fixed point (around 70-deg.). One has to move the eyes/head in order to see the field stop of the eyepiece (the field stop is the edge of the black circle that one sees when looking through an eyepiece). In this sense, it's like being in space, seeing all those stars from the periphery of the line of vision, as compared to looking through an ordinary plossl that came with the scope with around 50-deg. AFOV where you immediately see the borders (black circle) of the view. Some say "spacewalk" is just marketing lingo used to drum up sales of the new EP line, while others believe in it - it's very subjective and it's best to try it out if you can attend a local star party to see what it's all about.

    I have the 13mm Ethos, 20mm Nagler, and a 35mm Panoptic.........I have not had a chance to try the 13 out in my LX, but for now til I get the chance to test the Ethos out fully, the Panoptic 35 is still my favorite eyepiece......Nice FOV and razor sharp stars!

    Similar to that in the wide sense, but without the distortion.

    The "Spacewalk" sensation is the FOV which can go beyond your periphery of vision have to move the eye around a bit to take it all in....A very large FOV and it is not distorted so much across the FOV, and when looking at nice CLusters and such you get the feeling of just falling into the eyepiece sort of like the stars are surrounding you a little bit of 3d effect going on.....This is very pronounced in my 12" LX-200. The panoptic 35 was my first intro to this even had chance to view through panoptic in 20" Obsession which can leave one breathless when viewing clusters. I am still waiting to use the Ethos through my Lx, I have only used it through my 80mm scope so far, the view is vast in it, the real test is the 12" scope with it.

    Myself, I would go with a used 32mm Brandon eyepiece. You might get it for $150, just not new. I was amazed when I looked through it the other night ( having just picked it up at the last NEAF meet) - contrast and clarity were beyond reproach! Add a 2x barlow and it turns into a 16mm.
