The 28mm UWAN does not appear to be available any longer, but here is an old CN article about the line. Eye relief is an excellent 17 mm, longer than in more premium models, and the eyecup is extendable. F/7 is more forgiving than faster scopes so that does help. If you're not sensitive to curvature perhaps give it a go but honestly if you have on hand a 2x and a 3x barlow just get the 15mm because then you'll have all three. Very comfortable, bright and sharp. It's the same at low power, which Ernest just pointed out. Don't have an Astromart account? Will 1.25 inch eyepieces fit ES coma corrector? But then again, thats more or less the point the eyepiece gets out of the way so you no longer have the sense you are looking through a round porthole or window. I've owned all the WO UWAN in the past but sold off all of them except the 4mm. It is been known for a long time that the 7mm UWAN is closer to 8mm, so maybe the previously given field stop specifications have been misrepresented so that the focal length-FOV equation should add up on paper(?).
