The pictures are of the moon about 10pm EDT June 9, 2000.

On the left, with the shorter focal length of my two eyepieces. On the right, with the longer focal length eyepiece.

I think the longer focal length eyepiece gave the sharper image. In any case, it looks as if the limit of resolution is set by seeing and the telescope rather than by the digital camera.

Short focal length eyepiece on left, long f.l. on right

More extraordinary, here is a resized clip from an exposure with the longer focal length eyepiece but without the Barlow!

No barlow lens, long focal length eyepiece
