Heavenly?
A lot has been written about the wide field Ethos eyepieces. And all of that is true - it is genuinely a visual treat to see something in context. It is not the actual wide field itself - you have to move your head around to actually see that wide field, something you are unlikely to do when your interest is in the focal object. For me, the actual visual treat is that you do not get the 'looking down a microscope tube' effect of using the same magnification in narrow field designs. I find that makes you conscious of the equipment and kills immersion. In contrast, with the wide field of the Ethos, you have the experience of nothing in the way - almost like it was you suspended in space and watching this thing. Now if you did want to move your head around, you are going to be pleasantly surprised by how good performance out into the field is. It is also an optic that is very good at retaining contrast - with a narrowband filter, this eyepiece (compared to an Erfle type I compared it with) completely darkened the background sky while the other eyepiece still was a dark grey (I am in a somewhat light polluted area - I estimate around Bortle 5-6). You can read up the specs and pore over the resolution numbers etc. It is the immersion though - makes you spend more time at the eyepiece studying things.

Fantastic Eyepiece
This is an amazing eyepiece and a fantastic addition to our 21mm Ethos. The apparent field of view is stunning and the quality to the edge of the field of view is brilliant. We use this eyepiece on a 16” reflector and the views far surpass anything we’ve used before.
