What I am asking of you now, is if anyone knows how to make the 1.5x Erecting eye piece with the 4mm lens work? That one is used for daytime to look at distant objects in cities, and I just can't seem to figure it out... Everything I see is complete blur, no matter how much I play with the focus wheel...
Not bad. What eyepiece did you combine with the barlow?

The "erecting eyepiece" acts like a 1.5x barlow. With the 4mm eyepiece, you are operating at 700mm*1.5/4mm= 262x which is too much magnification for this telescope so this combination is unlikely to produce a good image, even if you manage to reach focus.

My suggestion: Try using the 4mm eyepiece (or better still, a longer one) in the star diagonal. As long as the diagonal is upright, the view will be upright too. Only mirrored.

If you really want to use the erecting eyepiece, ue it with a longer focal length eyepiece such as 8mm or more.
