Using the twist up eye guard will reduce the field of view, optimal viewing for that eyepiece seems to be with it wound in.
I sometimes forget mine has the twist up guard altogether .

Enjoy
The 8.8mm Meade 4000 UWA does not have a twist up eye guard. It only has a rubber eye cup that folds down. All eyepieces with fold down rubber eye guards seem to give a more immersive view when they are folded down.

On the other hand, the 8.8mm Series 5000 Meade UWA does have a twist up eye cup, which negates the immersive sensation if you twist it upwards as the eye relief on it is already short.

Sooby, if yours is the 8.8mm Series 5000, (with the blue on the outer casing), leave it in the "down" position, it works the best this way.

Cheers!
