I have a pair of 17.5 Morphei that I use with my TV Bino vue. I have to use the TV 2X amplifier to reach focus, but that actually helps when viewing the moon in my refractor to get me at a nice magnification to see detail at about a 1 mm exit pupil. I think they are wonderful eyepieces. I compared a 4.5 Delos and a 4.5 Morpheus in my refractor on a double star using the same telescope and diagonal and target on the same night. After switching between the two of them several times, the Delos had slightly less glare around the brighter component. This is the only difference I could distinguish between the two 4.5 mm eyepieces. I have a question, I see many people discuss taking rather extraordinary measures to avoid using a glass path compensator and I don't know why this is being done. Is it in an attempt to get a wider fov than a pair of 40 mm plossl eyepieces?

I agree. My 9 mm Delete is something special! Larry

I have the Baader 4.5 mm Morpheus, but I do not like the chromatic aberration it displays with bright stars. Larry
