THe Moon will have to wait as will Jupiter. These objects may prove to be interesting as test subjects.

It was interesting that with the CED2, light scatter from the air and/or the eyepiece was eradicated.

Other than the CA inherrent in an achromat, Venus had a very clean appearance.

Hi Sol,

Yes, long wait for Jupiter.

Did you notice any difference in brightness (transmission) from center to edge? I am guessing there is some gradient in coatings from center to edge. It's just my wild guess.
I may be totally off base

Recently, I compared very good wide AFOV eyepiece to excellent planetary eyepiece in light scatter and contrast. I saw Venus something similar to the first sketch (stock diagonal one) in very good wide AFOV eyepiece.

Then I saw something similar to your sketch with CED2 in excellent planetary eyepiece. I was a little bit stunned at the obvious difference. I realized that I've been missing something.

I observed similar result with the full Moon. I saw more details on bright Moon surface with the planetary eyepiece. I used to stay away from the full Moon but not any more

I haven't repeated the observation yet so I can't say it for sure, just seeing difference or something.

That's why I was curious about the full Moon. Let us know how you see when you get a chance to observe the full Moon with CED.
